Example usage for java.util.concurrent CyclicBarrier CyclicBarrier

Introduction

In this page you can find the example usage for java.util.concurrent CyclicBarrier CyclicBarrier.

Prototype

public CyclicBarrier(int parties, Runnable barrierAction) 

Source Link

Document

Creates a new CyclicBarrier that will trip when the given number of parties (threads) are waiting upon it, and which will execute the given barrier action when the barrier is tripped, performed by the last thread entering the barrier.

Usage

From source file:BarDemo.java

public static void main(String args[]) {
    CyclicBarrier cb = new CyclicBarrier(3, new BarAction());

    System.out.println("Starting");

    new MyThread(cb, "A");
    new MyThread(cb, "B");
    new MyThread(cb, "C");
