What is Java?
Java is a powerful, object-oriented programming language. It is platform-independent: write once, run anywhere. Java code is compiled into bytecode that runs on the Java Virtual Machine (JVM).
Every Java program starts with a class. The main method is the entry point.
JAVA
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
