import java.awt.event.*;
import java.util.*;
public class Puzzel extends JFrame {
          JButton[] arr = new JButton[15];
          String[] add = {"1.jpg","2.jpg","3.jpg","4.jpg","5.jpg","6.jpg","7.jpg","8.jpg","9.jpg","10.jpg","11.jpg","12.jpg","13.jpg","14.jpg","15.jpg"};
          int X;
          int Y;
          public Puzzel(){
                    Image image;
                    Toolkit toolkit= Toolkit.getDefaultToolkit();
                    image=toolkit.getImage("icon.jpg");
                    ImageIcon icon=new ImageIcon("icon.jpg");
                    setIconImage(image);
                    setTitle("Puzzal");
                    JMenuItem pic = new JMenuItem("Solved");
                    pic.setMnemonic('a');
                    JPanel jp = new JPanel(new GridLayout(4,4));
                    ArrayList list = new ArrayList();
MouseListenerClass M1 = new MouseListenerClass();
                       for(int x = 0; x < arr.length; x++)
                           arr[x] = new JButton(add[x], new ImageIcon(add[x]));
                           getContentPane().add(arr[x]);
                          list.add(arr[x]);
                    Collections.shuffle(list);
                    for(int x = 0; x < list.size(); x++)
                          jp.add((JButton)list.get(x));
                        getContentPane().add(jp);
                             pack();
                             setSize(427,427);
                                    setResizable(false);
                    /*for(int x=0;x<arr.length;x++){
                         arr[x].addSelectionListener(new SelectionAdapter());
               public void widgetSelected(SelectionEvent event){System.out.println("IN");
                    if (event.getSource().getClass().equals(Button.class)){
                         Button button = (Button) event.getSource();
                         if (button.getText().equals("") )
                              Toolkit.getDefaultToolkit().beep();
                              else
                                   this.swapPlaces(((Integer) button.getData()).intValue());
               public void widgetDefaultSelected(SelectionEvent event){
                              System.out.println("Widget was defaultselected: " + event.getSource());
           for(int x = 0; x < arr.length; x++)
          arr[x].addMouseMotionListener(M1);
          private class MouseListenerClass extends MouseMotionAdapter
               public void mouseDragged(MouseEvent E)
               X=E.getX();
               Y=E.getY();
               for(int x = 0; x < arr.length; x++)
                    arr[x].setBounds(X,Y,100,100);
public static void main(String[] args){
                new Puzzel().setVisible(true);}
     }
