How interrupt/stop a thread in Java?

Question

I\'m trying to stop a thread but I can\'t do that :

public class Middleware {

public void read() {
    try {
        socket = new Socket(\"192.168.1.8\", 20         


        

Answer 1

The usual way to stop a thread is to have a volatile flag and then check that in the run method. i.e.

class Scan extends Thread {
    volatile stop = false;
    public void run() {

        while (!stop) {
            try {
            // my code goes here

            } catch (IOException ex) {
                thread.currentThread().interrupt();
            }
        }
    }

    public void stop(){
        stop = true;
    }
}

You can then call scan.stop().
