import java.awt.*; import java.awt.event.*;  import javax.swing.*;  public class cballmaze extends jframe implements actionlistener  { //below have declared different objects have used throughout program  private jbutton buttonright, buttonleft, buttonup, buttondown, buttontl, buttontr, buttonbl, buttonbr, buttoncenter, optionone, optiontwo, optionthree, optionexit, scenarioact, scenariorun, scenarioreset, compassph; private jbutton [] game = new jbutton [208]; private jpanel panelcentre, panelright, panelbottom, buttonpanel, compasspanel, optionspanel, selectionpanel, panelact, panelrun, panelreset, panelslider; private jtextfield optiontf, squaretf, directiontf; private jlabel option, square, direction, compassdirection; private jslider speedslider; private string firstoption = "1", secondoption = "2", thirdoption = "3", updirection = "north", rightdirection = "east", downdirection = "south", leftdirection = "west"; private int i; private int[] map = new int[]         {         1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,2,         3,1,3,3,3,1,3,3,3,1,3,3,3,3,3,3,         3,1,3,3,3,1,3,3,3,1,3,3,3,3,3,3,         1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,         3,3,1,3,3,3,1,3,3,3,3,1,3,3,3,3,         3,3,1,3,3,3,1,3,3,3,3,1,3,3,3,3,         1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,         3,1,3,3,3,1,3,3,3,1,3,3,3,3,3,3,         3,1,3,3,3,1,3,3,3,1,3,3,3,3,3,3,         1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,         3,3,1,3,3,3,1,3,3,3,3,1,3,3,3,3,         3,3,1,3,3,3,1,3,3,3,3,1,3,3,3,3,         4,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,         }; 

and

    try     {         iconsand = new imageicon("sand.jpg");     }     catch (exception e)     {         system.err.println("sand icon "+e);     }      try     {         iconball = new imageicon("sand60x60.png");     }     catch (exception e)     {         system.err.println("ball icon "+e);     }      try     {         iconwhite = new imageicon("white32x32.jpg");     }     catch (exception e)     {         system.err.println("white icon "+e);     }      try     {         iconend = new imageicon("sandstone.jpg");     }     catch (exception e)     {         system.err.println("end icon"+e);     }      (i=0;i<208;i++)     {         game[i] = new jbutton ();          if(map[i]==1)         {             game[i].seticon(iconsand);         }         if(map[i]==2)         {             game[i].seticon(iconball);         }         if(map[i]==3)         {             game[i].seticon(iconwhite);         }         if(map[i]==4)         {             game[i].seticon(iconend);         }          game[i].setborder(null);         game[i].setpreferredsize(new dimension(32, 32));         game[i].addactionlistener(this);         panelcentre.add(game[i]); 

thanks help! here code panel center:

        setdefaultcloseoperation(exit_on_close);     container window = getcontentpane();     window.setlayout(new borderlayout() );      //panels      panelcentre = new jpanel();     panelcentre.setpreferredsize(new dimension(625, 450));     panelcentre.setbackground(color.black);     window.add(panelcentre);     panelcentre.setlayout(new gridlayout(21, 30));
