Some Groovy Threading

There is an example of using threads with Groovy in Venkat’s book.

He uses the GDK extension to Thread and calls Thread.start. I wondered if the main thread would wait until the started thread completed, and what would happen if you started another thread.

I made some changes, and ran it.

Here is my class:

Here is the result:


So the main thread gets to its last statement pretty quickly. The two threads run simultaneously. I already knew this, but it’s good to review threads every now and then.

I was always intimidated by threading and concurrent  programming. Maybe it’s not too bad in Groovy.

You’re welcome.
