hey there. I have the following code. I am trying to build an applet that displays all possible (92) ways of arranging eight queens on a chess board with no two of them on the same column, row, or diagonal. I built this as an application and it ran fine. I made the necessary modifications of my Eksi class to construct an applet, but it won't repaint(). can anyone lend their experience and show me what I am doing wrong. I think my problem is specifically on line 77 of my code. thank you!

```
import javax.swing.*;
import java.awt.*;
public class Eksi extends JApplet{
private Kutia[][] k;
private int count = 0;
public void init(){}
public void paint(Graphics g){
g.setColor(Color.blue);
g.fillRect(0, 0, 500, 500);
for(int i = 0; i < 8; i++){
for(int j = 0; j < 8; j++){
if((i+j)%2 == 0){
g.setColor(Color.black);
}
else{
g.setColor(Color.red);
}
g.fillRect(50 + i*20, 50 + j*20, 20, 20);
}
}
if(k != null){
System.out.println("Gagi");
count++;
for(int i = 0; i < 8; i++){
for(int j = 0; j < 8; j++){
g.setColor(Color.white);
g.drawString(k[i][j].figura(), i*20 + 52, j*20 + 70);
g.setColor(Color.black);
g.drawString("Mundesia " + count, 140, 30);
}
}
}
}
public void ndihmesePaint(Kutia[][] ituk){
k = ituk;
System.out.println("Ngadhnjim");
repaint();
}
public static void main(String[] args){
int variable = 0;
Model mod = new Model();
VeproMeMatrica vm = new VeproMeMatrica();
String[] ar = vm.permutim("8");
int[][] xarg = vm.ConvertPermute(ar);
Eksi ek = new Eksi();
Kutia[][] x = new Kutia[8][8];
for(int k = 0; k < vm.Factoriel(8); k++){
variable++;
for(int i = 0; i < x.length; i++){
for(int j = 0; j < x.length; j++){
if((i == 0 & j == xarg[k][0] - 1) || (i == 1 & j == xarg[k][1] - 1) || (i == 2 & j == xarg[k][2] - 1) || (i == 3 & j == xarg[k][3] - 1) || (i == 4 & j == xarg[k][4] - 1) || (i == 5 & j == xarg[k][5] - 1) || (i == 6 & j == xarg[k][6] - 1) || (i == 7 & j == xarg[k][7] - 1)){
x[i][j] = new Kutia(i, j , "M");
}
else{
x[i][j] = new Kutia(i, j, "");;
}
}
}
//-------------------------------------------------------------------
ek.ndihmesePaint(x);//this line is never being executed. I don't get it why!!
try { Thread.sleep(2000); }
catch (InterruptedException e) { }
