Java Basics

Start with a class and main method.

Java

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

Output

Hello Programonic

Explanation

Java code lives in classes. The main method is the entry point, and System.out.println prints a line.
