A GUI JAVA code..

I have this program, ((enter a bunch of integers in any order, and the buttons find the minimum and maximum of the integers, interactively.)) as this pic shows

the code is provided and all the job is ::

1- crate project and name it:: mm_al . Then, create a package and name it:: com.ra_al.mm. Then, create a class and name it: mm_al.
2- edit the code ( if it necessary) and run it in IntelliJ ide.
3- zip the project file..

import java.awt.Container;
import javax.swing.JFrame;



public class MnMaxPanel
{
  public MnMaxPanel() {}

  public static void main(String[] args)
  {
    JFrame frame = new JFrame("MinMax Finder");
frame.setDefaultCloseOperation(3);

frame.getContentPane().add(new MinMax());

frame.pack();
frame.setVisible(true);
}
