What are the differences between calling System.exit(0) and Thread.currentThread().interrupt() in the main thread of a Java program?

Question

Both cause a program to stop executing. It\'s clear that there must be some differences in how this happens, though. What are they?

Answer 1

If there are other (non-daemon) threads running, the JVM won't exit if you stop the main thread. System.exit() kills all the other threads.
