How do you kill a Thread in Java?

Question

How do you kill a java.lang.Thread in Java?

Answer 1

Attempts of abrupt thread termination are well-known bad programming practice and evidence of poor application design. All threads in the multithreaded application explicitly and implicitly share the same process state and forced to cooperate with each other to keep it consistent, otherwise your application will be prone to the bugs which will be really hard to diagnose. So, it is a responsibility of developer to provide an assurance of such consistency via careful and clear application design.

There are two main right solutions for the controlled threads terminations:

• Use of the shared volatile flag
• Use of the pair of Thread.interrupt() and Thread.interrupted() methods.
