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

Simply return; from your while and the thread will die, no need to call stop() or interrupt(). If you want to do it externally then use this pattern and call requestStop().

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

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

            } catch (IOException ex) {
                stop = true;
            }
        }
    }

    public void requestStop() {
        stop = true;
    }

}
