How to use JOptionPane in java?

 Little too busy in school:)
From the past few lessons here, we are running JAVA programs in cmd/text only interfaces. Now we will learn how JOptionPane class in java works to have an object oriented program.

    //import  JOptionPane class
     import javax.swing.JOptionPane;

   
     public class Joptionpanejava {
     public static void main(String[] args) {

         //e main line for JOptionPane
        JOptionPane.showMessageDialog(null,"WELCOME to magJAVAtayo!");
    }
}

     // showMesssageDialog  method is under  JOptionPane class and this method  requires two arguments. If a method requiures multiple arguments, these must be separated by comma(,). And the first argument will always be the keyword null
JOptionPane.showMessageDialog(first argument , second argument);


Output should be like this:

 If you want to print from user's input, edit the code to this.


// declare string variable
        String string1;
         //use showInputDialog method
        string1=JOptionPane.showInputDialog("Ano ang pangalan mo?");
   
        JOptionPane.showMessageDialog(null,"Hi "+string1+"! Kumusta?");

try this code to see the output.

More examples by request, basta kaya gawin ni author:)
