C, C++, and Java are three prominent programming languages, each with its own unique features and use cases. Here’s a detailed comparison of these languages across various aspects: ### 1. **Origin and Paradigm** – **C:** – **Origin**: Developed in the early 1970s by Dennis Ritchie at Bell Labs. – **Paradigm**: Procedural programming language. It focuses…

In Java, labeled loops are a way to give a name (label) to a loop, allowing you to control the flow of execution in nested loops. This is especially useful when you want to break out of or continue a specific outer loop from within an inner loop. Labels are essentially identifiers that you place…

In Java, literals are specific values that are directly used in the code, and they represent constant values. Java literals can be categorized into several types based on the kind of data they represent. Here’s a breakdown of the different types of literals in Java: 1. Integer Literals These are whole numbers without any fractional…

In Java, type casting refers to the process of converting a variable from one type to another. This is necessary when you need to assign a value of one data type to a variable of another data type. Java supports two main types of casting: implicit (automatic) and explicit (manual). 1. Implicit Casting (Automatic Casting)…

In Java, tokens are the smallest units of code that have meaning in the language. They are the building blocks of Java programs and can be categorized into several types: 1. Keywords Keywords are reserved words in Java that have special meanings in the language. They cannot be used as identifiers (names for variables, methods,…

public class A { static int print(int a) { System.out.println(“I am print function”); return 10; } static void print2() { System.out.println(“I am print function2”); } static void print3(int a) { System.out.println(“I am print function3”); //return 10; } static int print4() { System.out.println(“I am print function4”); return 10; } public static void main(String[] args) { int…

public class OperatorDemo { public static void main(String[] args) { // Variable Declaration int a = 10; int b = 5; boolean result; // Arithmetic Operators int sum = a + b; int difference = a – b; int product = a * b; int quotient = a / b; int remainder = a %…

Inheritance is a fundamental concept in object-oriented programming (OOP) that allows one class to inherit the properties and behaviors (fields and methods) of another class. In Java, there are several types of inheritance, each serving a different purpose: 1. **Single Inheritance**: In single inheritance, a class (the subclass or derived class) inherits from only one…

In Java, tokens are the smallest units of a program that have a meaning. They are the building blocks of the Java programming language. When you write Java code, the compiler breaks it down into these tokens for further analysis and processing. The main types of tokens in Java are: Keywords: These are reserved words…

Encapsulation is one of the fundamental concepts of object-oriented programming (OOP) in Java. It is the technique of bundling the data (variables) and the methods (functions) that operate on the data into a single unit, called a class. Encapsulation is used to hide the internal state of an object from the outside world and only…
