QA Cheatsheet

Java Thread suspend() method: The suspend() method of thread class puts the thread from running to waiting state. This method is used if you want to stop the thread execution and start it again when a certain event occurs. This method allows a thread to temporarily cease execution. The suspended thread can be resumed using the resume() method.

Java Thread interrupt() method: The interrupt() method of thread class is used to interrupt the thread. If any thread is in sleeping or waiting state (i.e. sleep() or wait() is invoked) then using the interrupt() method, we can interrupt the thread execution by throwing InterruptedException.

If the thread is not in the sleeping or waiting state then calling the interrupt() method performs a normal behavior and doesn’t interrupt the thread but sets the interrupt flag to true.
