How can you ensure in java that a block of code can not be interrupted by any other thread

Question

exampl:

new Thread(new Runnable() {
  public void run() {
    while(condition) {

      *code that must not be interrupted*

      *some more code*
    }
  }         


        

Answer 1

Best halfway solution would be to synchronize all threads on some common object so that no other threads are runnable while you're in the critical section.

Other than that I do not think it's possible. And I'm quite curious as to what kind of problem that requires this type of solution ?
