How do you kill a Thread in Java?

Question

How do you kill a java.lang.Thread in Java?

Answer 1

You can kill a thread by setting a class variable and using it as a sentinel.

Class Outer {

    public static volatile flag = true;

    Outer() {

        new Test().start();

    }

    class Test extends Thread {

        public void run() {

            while (Outer.flag) {

                //do stuff here

            }

        }

    }

}

Set an external class variable, i.e. flag = true in the above example. Set it to false to 'kill' the thread.
