Buttons doesnt show on the applet

Question

I wrote a code which takes coordinates of buttons from another class and set it to buttons bounds and then add it to contentpane but the problem is buttons doesnt show on the applet.
Here is my code
any help would be usefull
package applet;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.ImageIcon;
import java.io.*;
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import images.*;
import hareket.*;
public class backgammon extends JApplet
public Icon puls_icon,bgicon,pulk_icon;
private Image pul_s,background,pul_k;
private JLabel bg;
private JButton[] butonlar;
private sari sariplayer;
private kahverengi kahveplayer;
private kareler board;
    public void init()
        getContentPane().setLayout(null);
        this.setSize(744, 536);
        butonlar = new JButton[31];
        board = new kareler();
        sariplayer = new sari(board);
        kahveplayer = new kahverengi(board);
        sariplayer.setkahverengi(kahveplayer);
        kahveplayer.setsari(sariplayer);
        kahveplayer.baslangic("kahverengi");
        sariplayer.baslangic("sari");
        pul_s = getImage(getCodeBase(),"images/pul_sari.gif");
        pul_k = getImage(getCodeBase(),"images/pul_kahverengi.gif");
        background = getImage(getCodeBase(),"images/background.jpg");
        puls_icon = new ImageIcon(pul_s);
        pulk_icon = new ImageIcon(pul_k);
        bgicon = new ImageIcon(background);
        bg=new JLabel(bgicon);
        bg.setBounds(0,0,getWidth(),getHeight());
        getContentPane().add(bg);
        butoninitialize();
    public void butoninitialize()
            for (int i=1;i<31;i++)
                if (i<16)
                    butonlar[i] = new JButton(pulk_icon);
                    butonlar.setBounds(kahveplayer.pullar_x[i],kahveplayer.pullar_y[i],42,42);
else
butonlar[i] = new JButton(puls_icon);
butonlar[i].setBounds(sariplayer.pullar_x[i],sariplayer.pullar_y[i],42,42);
butonlar[i].setContentAreaFilled(false);
butonlar[i].setBorderPainted(false);
this.getContentPane().add(butonlar[i]);
Thanks

Answer 1

The second method will not work unless you have JDK 1.5.
I simplified your code a bit to make it compilable.
This solution should work:
package applet;
import javax.swing.*;
import java.awt.*;
public class backgammon_1 extends JApplet {
    public Icon puls_icon,bgicon,pulk_icon;
    private Image pul_s,background,pul_k;
    private JLabel bg;
    private JButton[] butonlar;
    public void init() {
        getContentPane().setLayout(null);
        this.setSize(744, 536);
        butonlar = new JButton[31];
        pul_s = getImage(getCodeBase(),"images/pul_sari.gif");
        pul_k = getImage(getCodeBase(),"images/pul_kahverengi.gif");
        background = getImage(getCodeBase(),"images/background.jpg");
        puls_icon = new ImageIcon(pul_s);
        pulk_icon = new ImageIcon(pul_k);
        butoninitialize();
        bgicon = new ImageIcon(background);
        bg=new JLabel(bgicon);
        bg.setBounds(0,0,getWidth(),getHeight());
        getContentPane().add(bg);
    public void butoninitialize() {
        for (int i=0;i<butonlar.length;i++) {
            if (i<16) {
                butonlar[i] = new JButton(pulk_icon);
                butonlar.setBounds(50*i,50,50,50);
} else {
butonlar[i] = new JButton(puls_icon);
butonlar[i].setBounds(50*(i-16),100,50,50);
butonlar[i].setContentAreaFilled(false);
butonlar[i].setBorderPainted(false);
this.getContentPane().add(butonlar[i]);
