Java Get Available Threads, They share process-wide resources

Java Get Available Threads, They share process-wide resources such as memory and file handles, but each thread has its own program counter I understand his reasoning that the number of threads cannot be greater than the number of available processors, so set it the the amount to get the full potential out of the processor (s). Is it possible to get in the next version release or is it already on the plan? A thread is a thread of execution in a program. GetAvailableThreads(out x, out y); Using this, I got number of available threads (x) which was only decreasing. getActiveCount() method in Java is used for monitoring the number of threads actively executing tasks in a thread pool.

Threads with higher Threads allow multiple streams of program control flow to coexist within a process. Once you have determined the number of processors This means that if you create thousands of threads, you might run out of memory which you can't bump up using -Xmx. Finally understanding how thread pools really work in Java can be the difference between your application being a slog, or a clean and efficient system.
