Is there a good way to forcefully stop a Java thread?

Question

I want to stop a Java thread immediately but when I try the thread always takes some time before stopping. Is there a good way to force a Java thread to stop instantly?

Answer 1

Running Thread cannot be stopped using Thread.Interrupt , only waiting or blocking threads can be stopped using Thread.Interrupt.But using a shared variable to signal that it should stop what it is doing. The thread should check the variable periodically,(ex : use a while loop ) and exit in an orderly manner.

private boolean isExit= false;

public void beforeExit() {
    isExit= true;
}

public void run() {
    while (!isExit) {

    }
}
