Hi,

I have written a class that keeps track of the number of threads
running. My problem is that I don't know how to update the label:
"Number of current threads is: "
Any hints?

cheers,

Part of gui code:
=================
//Add panel with number of threads
        GridBagConstraints threadsTextConstraints = new GridBagConstraints();
        threadsTextConstraints.gridx = 0;
        threadsTextConstraints.gridy = 6;
        threadsTextConstraints.gridwidth = 2;
        threadsTextConstraints.gridheight = 1;
        threadsTextConstraints.fill = GridBagConstraints.HORIZONTAL;
        threadsLabel = new JLabel("Number of Threads is
"+tc.getNumberOfThreads());
        threadsLabel.setAlignmentX(JLabel.RIGHT_ALIGNMENT);
        gridbag.setConstraints(threadsLabel, threadsTextConstraints);
        this.add(threadsLabel);

Thread class:
=============
public class ThreadCounter implements Runnable {
    private Exercise2Model model;
    private int numberOfThreads = 0;
    public ThreadCounter(Exercise2Model model){
        this.model = model;   
    }
   
    public void run() {
        while (true) {
            try {
                Thread.sleep(10);
                int nrOfThreads = model.getNumberOfThreads();
                this.setNumberOfThreads(nrOfThreads);
            } catch (InterruptedException ie) {
                System.err.println("Thread has been interrupted");
            }
           
        }
    }
   
    public String getNumberOfThreads(){
    return    Integer.toString(numberOfThreads);   
    }
   
    public void setNumberOfThreads(int nrOfThreads){
        if (numberOfThreads == nrOfThreads){
            //There is no change. Don't do anything.
        }else{
        //There has been a change
        numberOfThreads=nrOfThreads;
        System.out.println(numberOfThreads);
        }
    }
}
