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

Before a thread is interrupted, security manager's checkAccess() method is called. Implement your own security manager, call System.setSecurityManager to install it and make sure it doesn't let any other thread interrupt you while it is in critical section.
