Getting Started with Java

Create a Class

A Java program needs an entry and a class to host its entry. The filename must match the classname.

• Create Main.java

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello World");
    }
}

• Compile the program

javac Main.java

• Run the file

java Main

• The output should read

Hello World
