On the previous page, we looked at how to construct a thread in Java, via the Runnable and Thread objects. We mentioned that the Thread class provides control over threads. So on this page, we take a high-level
Both methods are synchronized, so that in theory a call to addJob() can't be run while the stop request method is running and waiting for the thread to finish: public class Processor extends Thread { private volatile boolean stopRequested; public synchronized void requestStopAndWaitToFinish() ...
If the method is executing concurrently in different threads, each thread has its own version of the method’s local variables. A method’s arguments also serve as local variables within the scope of the method; the only difference is that they are initialized by being passed in from the ...

In future releases, extproc might be a multithreaded process. Therefore, be sure to write thread-safe external procedures. That way, they will continue to run properly if extproc becomes multithreaded. In particular, avoid using static variables, which can be shared by routines running in separate...

For basic Java object capabilities, you can use COBOL object-oriented language. For additional Java capabilities, you can call JNI services. Because Java programs might be multi-threaded and use asynchronous signals, compile your COBOL programs with the THREAD option. Parent topic: COBOL on z/OS...
