Do threads ever commit suicide or stop running

When will this thread stop running and stop existing? Will it stop running immediately after printing the number 10? Is it available for garbage collection immediately after printing 10? Or must I explicitly interrupt it or something?

Runnable counter = new Runnable() {
  @Override
  public void run() {
    for (int i =0; i<=10; i++) {
      System.out.println(i);
    }
  }
};
new Thread(counter).start();
Solution

  • A thread doesn't commit suicide. It simply terminates or gets aborted (say, killed).

    There is an important factor that justifies the usage of a so brutal term, killing, for process and threads: their state is not saved and transactional integrity is not directly guaranteed unless you have another mechanism.

    In your case, the thread will simply print from 1 to 10 and terminate, being garbaged the next time GC runs.

    Nothing more.
