Java Tutorial
Java is an object-oriented programming language. The Java programming language was designed in the early 90s and later quickly became one of the most popular languages in the world. If this programming language initially wrote code on one operating system, it would not be possible to run that code on another operating system. Programs written in Java can be run on any operating system only if there is a Java Virtual Machine (JVM) for that operating system. The Java program is object-oriented so it is very easy to write very long code and get rid of errors.
When code is written for a Java program, that code is not compiled and converted directly into machine code. And those codes come in an intermediate state called byte code which contains .class files. This class file cannot be executed alone but must be executed through a virtual machine. Here, the byte code that is created is not human-readable. It can only understand Java virtual machines.
The most interesting thing about Java is that it is possible to run this program once on any other operating system. So the slogan of this program is Write Once, Run Anywhere (WORA).
File Name Main.java
import java.util.*;
public class Main {
public static void main(String[] args) { public static void main(String[] args) { public static void main(String[] args) { public static void main(String[] args) {
System.out.println("Hello, World!");
}
}Output:-
Hello World
