Most developers work with threads at one point or another. It can be important to know which threads are active to accomplish a given task. The following API activeCount on the Thread class returns the count of the active threads in the current run time.
public class ActiveThreadsCount{ public static void main(String args[]) { ActiveThreadsCount activeThreadsCount = new ActiveThreadsCount(); activeThreadsCount.countThreads(); } private void countThreads() { //This can be invoked at a complex code segment and you cn determine the count int threadsCount = java.lang.Thread.activeCount(); System.out.println("Count of active threads: " + threadsCount); }}
