How to stop a thread and invoke another

Question

My program running on a one thread. And I have another thread and I want to stop current thread and invoke the second thread. And after second thread stops I want to invoke the first thread again. How can I do this. Please help me.

Answer 1

You're looking for Thread.join method

like this (thread2 is the other thread you wanna wait for)

thread2.start();
thread2.join();
System.out.println("Done");

Answer 2

Use public final void join(long ms); method. Invoke it in your current thread.
