Javax.swing.Timer not working or event not being captured by actionPerfrmd

Question

Here is the code:
public class nQueensEst extends JApplet implements ActionListener {
  public Timer t = new Timer(1, this);
//...the actionPerformed:
if(e.getSource() == jButton1){
            nRainhas=Integer.parseInt(javax.swing.JOptionPane.showInputDialog("Quantas rainhas voc? deseja?"));     
            t.start();
            int contadorTentativas=1;
            for(int i=0; i<=100; i++){
                sol=new int[nRainhas];
                while(!rainhas()){
                  jLabel1.setText(contadorTentativas +" tentativas!!!");
                  contadorTentativas++;            
                jLabel2.setText("Solu??es: "+Integer.toString(i));
t.stop();
}else if(e.getSource() == t){
     System.out.println("timer");
     rodadas++;
Any clue?
Thanks

Answer 1

Let me explai the context: i had to implement a classic nQueens problem using a Grasp Algorithm and a Backtrack algorithm, then in dorder to compare them, i want to make the garap one to run find 100000 solutions and register the time it is needes, then divide by 100000. so i need the timer running and making a variable increase every millisecond from the beggining until the end of the last solution. But the timer is not generating a event or the event is not being caought by the actionPerformed.
