3. Write a program to print the area of a rectangle of sides 2 and 3 units respectively.

 public class Main {

      public static void main(String[] args) {

          int area = 2 * 3;

          System.out.println("The area is : " + area);

     }

NOTE:

• Used multiplication(*) operator to multiply.
• Didn't need Scanner class as input was already given.
• Used int because there was no decimal in the input.
