- [For-Each Loop in Java: Syntax, Examples](https://infitechx.com/for-each-loop-in-java/): The for-each loop in Java is a powerful looping construct that allows you to iterate through each item in an array or a collection more clearly. This construct was introduced in Java SE 5.0 and is also known as enhanced for loop in Java. The for-each loop provides a simple and concise way to traverse elements of arrays and collections without the complexity of the traditional for loop. It automatically retrieves each element without requiring index handling. You can use this loop when you want to access every element but do not need to modify or track the index. Syntax […]
- [While Loop in Java: Syntax, Example](https://infitechx.com/while-loop-in-java/): A while loop in Java is an entry control flow statement that allows a block of code to be executed repeatedly based on the specified Boolean condition. This is one of the simplest looping constructs. When we don’t know the number of iterations beforehand, we mainly use the while loop. For example, suppose you are trying to guess a password on your phone. You don’t know how many attempts it will take to get it right — maybe 1 try, maybe 5 tries. So, the logic goes like this: Once the password is correct, the loop stops. Syntax of While […]
- [For Loop in Java: Syntax, Examples](https://infitechx.com/for-loop-in-java/): A for loop in Java is an entry-controlled flow statement that allows you to execute a block of code multiple times based on a condition. You should use a for loop when you know exactly how many iterations you need to perform. For example, if you want to print numbers from 1 to 10, the for loop is the most efficient tool to do so. The for loop in Java is one of the most powerful and frequently used constructs for automating repetitive tasks. Whether you’re iterating through arrays, processing collections, or simply printing numbers, the for loop is your […]
- [Nested If-Else in Java: Syntax, Examples](https://infitechx.com/nested-if-else-in-java/): When you place an if-else statement inside another if or else block, it is called nested if-else in Java. A nested if-else statement means placing an if-else statement inside another if-else block. This allows you to evaluate multiple conditions one after another in a structured way. It enables you to precisely control over program flow. Nested if-else statements are especially useful in Java programming when decisions depend on multiple interrelated criteria. Basic Syntax of Nested If-Else in Java The general syntax for defining nested if-else statements in Java is as: In the above syntax of nested if-else statements, Basic Example […]
- [If Else in Java: Syntax, Examples](https://infitechx.com/if-else-in-java/): In this tutorial, you will learn about if-else in Java with syntax and practical examples. The if-else statement is one of the most fundamental decision-making statements in Java programming. It is a conditional control statement that allows your program to execute different code blocks based on specific conditions. An if-else statement executes a block of code if the given condition evaluates to true; otherwise, it executes another block of code. The condition is a boolean expression that determines the program’s flow depending on whether it’s true or false. In simple terms, the if-else statement helps Java programs make logical decisions, […]
- [Java instanceof Operator – Syntax, Examples](https://infitechx.com/java-instanceof/): In this tutorial, we will explore the Java instanceof operator in detail with syntax, and examples. When you are working with object-oriented programming in Java, you may need to check the type of an object before performing an operation. For this, Java provides instanceof operator, which helps in type checking at runtime and prevents ClassCastException. What is instanceof Operator in Java? The instanceof operator in Java is a binary operator used to test whether an object is an instance of a specific type. This “type” can be a class, a subclass, or an interface. It returns a boolean value true […]
- [Ternary Operator in Java: Syntax, Examples](https://infitechx.com/ternary-operator-in-java/): The ternary operator in Java is a shorthand way of writing simple if-else statements, which makes your code more concise and clean. This operator is also known as the conditional operator because it makes decisions based on a boolean condition. In Java, the ternary operator is represented by the symbols (? :). This is the only conditional operator in Java that takes three operands. Basic Syntax of Ternary Operator in Java The general syntax of ternary operator in Java is as: In the above syntax, The ternary operator evaluates a boolean expression and returns one of two values: one when […]
- [Bitwise Operators in Java with Examples](https://infitechx.com/bitwise-operators-in-java/): Bitwise operators in Java are special symbols that perform operations directly on the binary representation (0s and 1s) of integer values. For example: When a bitwise operator is applied, Java processes these binary digits individually. Bitwise operators are widely used in programming for: Types of Bitwise Operators in Java Java provides six main bitwise operators: Let’s explore each operator in detail with syntax, examples, and explanations. Bitwise AND Operator (&) The bitwise AND operator is a binary operator that compares each bit of two numbers. It is represented by the single ampersand symbol &. If both corresponding bits are 1, […]
- [Unary Operators in Java with Examples](https://infitechx.com/unary-operators-in-java/): In this tutorial, we will learn unary operators in Java with the help of examples. A unary operator is an operator that requires only one operand to perform an operation. You can use this operator to increment/decrement a value, negate an expression, or invert a boolean value. For example: In this example, the value of variable a is 5, but the value of variable b becomes -5 because the unary minus operator negates the value. Types of Unary Operators in Java Java supports six types of unary operators which are as follows: Let’s discuss them one by one with examples. […]
- [Basic Computer Knowledge: A Complete Guide for Beginners](https://infitechx.com/basic-computer-knowledge/): In the digital age today, basic computer knowledge is no longer optional.

A computer is an electronic device or machine that processes […]
- [Logical Operators in Java with Examples](https://infitechx.com/logical-operators-in-java/): Logical operators in Java are boolean operators used to combine multiple conditions in decision-making and looping constructs. They allow you to evaluate multiple boolean expressions and determine the flow of execution based on the overall result. Here’s simple example of using logical operators in Java in which we have used the OR (||) operator to combine two boolean expressions: In this example, we have used || operator that checks if at least one condition is true. Since isWeekend is true, so the whole expression becomes true. Therefore, “You can relax today!” is printed on the console. Types of Logical Operators […]
- [Relational Operators in Java: Syntax, Examples](https://infitechx.com/relational-operators-in-java/): Relational operators in Java are symbols used to compare between two values (i.e. operands) or expressions. These comparisons determine the relationship between the operands and always return a boolean value either true or false. Relational operators are commonly used in: List of Relational Operators in Java There are six relational operators in Java programming which is shown in the below table. Operator Description Example == Equal to x == y != Not equal to x != y > Greater than x > y < Less than x < y >= Greater than or equal to x >= y <= Less […]
- [Assignment Operator in Java: Syntax, Examples](https://infitechx.com/assignment-operator-in-java/): The assignment operator is one of the most fundamental operators in Java programming language. This operator is used to assign a value to a variable. The assignment operator is represented by equal (=) symbol. It is a binary operator that takes two operands. The value of the right-hand operand is assigned to the left-hand operand. The left-hand operand must be a variable. The general syntax is as follows: This operator assigns the value on the right-hand side to the variable on the left-hand side. For example, Here, num = 20 uses the assignment operator (=). In this example, 20 is […]
- [Operators in Java: Arithmetic Operators, Examples](https://infitechx.com/operators-in-java/): In this tutorial, we will learn about what operators are and different types of operators available in Java programming. Java provides a rich set of operators that are used to combine constants, variables, and sub-expressions to form expressions. An operator in Java or any other programming languages is a symbol that performs a specific kind of operation on one, two, or three operands and produces a result. The type of the operator and its operands determines: We can categorize Java operators based on two criteria: Types of Operators Based on Operands In Java, there are three types of operators based […]
- [Access Modifiers in Java with Examples](https://infitechx.com/access-modifiers-in-java/): Access modifiers in Java are keywords that determine the visibility and accessibility of classes, methods, constructors, and variables within different parts of a program. They help to restrict unauthorized access to sensitive data. In Java programming, there are four types of access modifiers: Types of Access Modifiers in Java 1. Private Access Modifier The private access modifier is the most restrictive modifier that is accessible only within the same class. This modifier encapsulates the data member and restrict the access. Example 1: Let’s write a Java program in which we will declare private members inside the class and try to […]
- [Top 4 Practical Use of Constructor in Java](https://infitechx.com/use-of-constructor-in-java/): In this tutorial, we will learn about the real-time use of constructor in Java programming with the help of basic to advanced examples. We know that constructors are a fundamental concept in Java programming, which plays a crucial a role in object initialization. A constructor in Java is a block of code that is used to initialize a newly created object. It is a special type of method that is automatically invoked when you create an object of a class. A constructor has the same name as the class and does not have a return type, not even void. You […]
- [Types of Constructor in Java](https://infitechx.com/types-of-constructor-in-java/): A constructor in Java is a special type of a method which is used to initialize objects. In other words, a constructor is a block of code that initializes an object. When you create an object of a class, at least one constructor is invoked. Unlike regular methods, constructors have the same name as the class and do not have a return type. They are invoked automatically when you create an object of class. Understanding constructors is fundamental to gain the basic knowledge of Java because they play an important role in object creation and class behavior. In this tutorial, […]
- [Instance Method in Java](https://infitechx.com/instance-method-in-java/): An instance method in Java is a non-static method that belongs to an object (or an instance) of a class. It does not tie up with class itself. You can use this type of method to define behavior that operates on the instance variables (data) of the class. Inside the instance method, you can access instance variables and invoke other instance methods of the same class. The statements inside an instance method are executed when you call it using an object of the class. Although all objects share the same method code, each method operates on the instance-specific data of […]
- [Methods in Java](https://infitechx.com/methods-in-java/): In this tutorial, we will learn about methods in Java programming. A method in Java is a block of code that performs a specific task. In other words, it is a group of statements that perform an operation. You can reuse methods throughout a program to avoid repetition. When you call the method, statements inside the method will execute. If you don’t call it, then its code will not execute. In Java, methods help in organizing code, improving readability, and reducing redundancy. They are fundamental aspect of object-oriented programming (OOP), allowing you to define define the behavior of classes and […]
- [What is Constructor in Java](https://infitechx.com/constructor-in-java/): A constructor in Java is a special type of method that is used to initialize the state of an object, assign default values, and perform any essential setup operations. It is automatically called when you create an instance (or an object) of a class. Unlike regular methods, constructors have the same name as the class and do not have a return type, not even void. In object-oriented programming language, Java constructors play a significant role by setting up initial values and ensuring proper object initialization before use. Syntax of a Constructor in Java The basic syntax to create a constructor […]
- [Reference Variable in Java](https://infitechx.com/reference-variable-in-java/): A reference variable in Java is a variable that holds the memory address (or reference) of an object rather than the object itself. When you create an object in Java, the object is stored in the heap memory, and the reference variable holds the reference to that object. In other words, the reference variable points to that memory location. For example, consider the following below code: In the above example, str is a reference variable of type String that points to a String object containing the text “Hello, World!”. The actual object is stored in the heap memory, while str […]
- [Instance Variables in Java (with Examples)](https://infitechx.com/instance-variables-in-java/): When you declare non-static data fields or variables within a class but outside any method, constructor, or block, they are called instance variables in Java. These variables are also called non-static variables in Java because they are not defined with static keywords. Instance variables are tied to individual objects (or instances) of the class, meaning each object of the class gets its own copy of these variables. Therefore, they can hold different values or data for each instance. Instance variables in Java are used to define attributes (i.e. properties) or the state of a particular object. Since they are members […]
- [Local Variables in Java](https://infitechx.com/local-variables-in-java/): Variables that are declared inside a method, constructor, or block are called local variables in Java. They are accessible only within that scope in which they are defined. Therefore, the scope of these variables is limited to the block, method, or constructor where they are declared. Local variables are not accessible outside their scope due to scoping rules. In other words, local variables are visible within the methods only and, therefore, their scope is local. Following are the key points of local variables in Java. They are as follows: Syntax to Declare Local Variables in Java The general syntax to […]
- [Variables in Java](https://infitechx.com/variables-in-java/): In this tutorial, we will learn about variables in Java programming. A variable is a container in Java that holds data or value during the execution of a program. In other words, a variable is a named location in the memory of the computer where the values are stored. It has a name, a type and a value. Each variable is associated with a data type that determines the kind of data or value it can store. For example, if you define a variable to store an integer value, you can’t use it to store a decimal fraction value, such […]
- [Non-Primitive Data Types in Java](https://infitechx.com/non-primitive-data-types-in-java/): In the Java programming language, data types are broadly categorized into two groups: primitive data types and non-primitive data types. Non-primitive data types are those data types in Java that are used to store multiple values. These data types are also called user-defined data types because they are created by users or programmers. Non-primitive data types do not store the actual value or data directly. Actually, they store a reference or memory address where the actual data is stored. In other words, when you define non-primitive data types, it refers to the memory location in the heap memory where the […]
- [Primitive Data Types in Java](https://infitechx.com/primitive-data-types-in-java/): In this tutorial, we will learn about primitive data types in Java. A data type represents the type of data that a variable can hold. For example, you declare a variable like this: In the above declaration, there are three parts. The first is the data type, which determines the type of data the variable will store. Here, int is a keyword that specifies the data type of the variable. It indicates that the variable age can only store an integer value. The second part of a declaration is the variable name (i.e. age), called identifier. It allows the program […]
- [Hello World Program in Java](https://infitechx.com/java-hello-world-program/): The “Hello World!” program in Java or any other programming languages is the first and basic program that beginners write it. The main purpose of writing this program is to understand the basic syntax and structure of the program.

Hello World Program Line-by-Line Explanation Now, let’s break down the above Java hello world program line by line. 1. public class HelloWorld […]
- [Structure of Java Program](https://infitechx.com/structure-of-java-program/): In this tutorial, you will learn about structure of Java program and its various components with the help of example. Basically, a Java program involves the following components: Documentation Section in Structure of Java Program Documentation is the first section in the structure of Java program which consists of comment lines and descriptive text that provide information about the program, such as its name, the programmer’s name, date, and a brief description of its purpose or functionality. Java documentation involves inline comments, block comments, and JavaDoc comments, which can be used to generate professional HTML documentation. JavaDoc comments start with […]
- [New Keyword in Java](https://infitechx.com/new-keyword-in-java/): The new keyword is a reserved keyword in Java programming which is used to create a new object or instance of a class. It allocates memory on the heap for the object and returns a reference to that memory. The reference returned by the new operator represents the memory address of the created object in the heap. This reference is stored in a stack memory which is represented by a variable which is called an object reference variable. This variable is used to access the fields (i.e. variables) and methods of the object. The basic syntax to use new keyword […]
- [What is Object in Java (with Examples)](https://infitechx.com/object-in-java/): In this tutorial, we will learn about what is object in Java with the help of realtime examples. An object in Java is a named entity that encapsulates state (attributes) and behavior (methods). In other words, a real-world entiry that has state and behavior is called object. It is a basic element of an object-oriented programing system. An object consists of related data and instructions for performing actions on that data. Here, the state represents properties and behavior represents actions. The best way to define an object is, what you see around you in real-life are all objects. Book, pen, […]
- [What is Class in Java (with Examples)](https://infitechx.com/class-in-java/): We know that Java is a pure object-oriented programming language that allows us to develop a program by using the concept of class and object. A class encapsulates the basic structure of a Java program in a single unit. A class in Java is a template or a blueprint that can be used to create objects of the same type. It is a fundamental building block of a pure object-oriented programming language like Java. A class represents a group of objects that share common properties (attributes) and behavior (methods). For example, if “computer” is a class, supercomputer, mainframe computer, minicomputer, […]
