Waiting on threads
- by Paul Reiners
I have a method that contains the following (Java) code:
doSomeThings();
doSomeOtherThings();
doSomeThings() creates some threads, each of which will run for only a finite amount of time. The problem is that I don't want doSomeOtherThings() to be called until all the threads launched by doSomeThings() are finished. (Also doSomeThings() will call methods that may launch new threads and so on. I don't want to execute doSomeOtherThings() until all these threads have finished.)
This is because doSomeThings(), among other things will set myObject to null, while doSomeOtherThings() calls myObject.myMethod() and I do not want myObject to be null at that time.
Is there some standard way of doing this kind of thing (in Java)?
