Returns an estimate of the number of active threads in the current thread's java.lang.ThreadGroup thread group and its subgroups.

Usage

From source file:Main.java

public static void main(String[] args) {

    Thread t = Thread.currentThread();
    t.setName("java2s.com thread");

    System.out.println("Thread = " + t);

    int count = Thread.activeCount();
    System.out.println("currently active threads = " + count);

    Thread.dumpStack();//from  ww w  .ja  v a  2 s  .com
}
