kill parent and retain child process?

Expand Post »

Is there anyway to create a new thread..basically create an object of a class within an existing thread and kill this existing thread so only the newly created child remains?

Re: kill parent and retain child process?

uth,

You can create a new thread at any time. Then if you so desire, let the 'main' thread die by letting the 'public static main' function return. If the thread you created is a 'daemon' thread the JVM will exit all together. However if the thread you created was a 'user' thread the JVM will not exit straight away, instead another thread will be automatically created called 'DestroyJavaVM' which will wait until all 'user' threads return and then kill the JVM. But why would you want to do this, one thread is as good as any other.

Hi Kate,

What I need to do is have another instance of the same class running and shut down the existing instance. Will try what you suggested today!Thanks!
