Answer 1

import javax.swing.JOptionPane;

public class BasicGUI {

      public static void main(String[] args) {

            // TODO Auto-generated method stub

            //Showing the Welcome message in Dialog Box

            JOptionPane.showMessageDialog(null, "Welcome");

            //Asking the User to input a number

            String input = JOptionPane.showInputDialog("Enter a Number");

            //Converting the string version of number to Integer version

            int num = Integer.parseInt(input);

            //Showing the appropriate message for even or odd

            if(num%2==0){

                  JOptionPane.showMessageDialog(null, num+" is even number");

            }

            else{

                  JOptionPane.showMessageDialog(null, num+" is odd number");

            }

      }

}
