Set running time limit on a method in java

Question

I have a method that returns a String, is it possible that after a certain time treshold is excedeed fot that method to return some specific string?

Answer 1

You can use AOP and a @Timeable annotation from jcabi-aspects (I'm a developer):

@Timeable(limit = 1, unit = TimeUnit.SECONDS)
String load(String resource) {
  while (true) {
    if (Thread.currentThread.isInterrupted()) {
      throw new IllegalStateException("time out");
    }
    // execution as usual
  }
}

When time limit is reached your thread will get interrupted() flag set to true and it's your job to handle this situation correctly and to stop execution.
