Java: set timeout on a certain block of code?

Is it possible to force Java to throw an Exception after some block of code runs longer than acceptable?

Answer

Yes, but its generally a very bad idea to force another thread to interrupt on a random line of code. You would only do this if you intend to shutdown the process.

What you can do is to use Thread.interrupt() for a task after a certain amount of time. However, unless the code checks for this it won’t work. An ExecutorService can make this easier with Future.cancel(true)

Its much better for the code to time itself and stop when it needs to.
