2025年3月21日 | 阅读 1 分钟

awaitAdvance() 方法属于 Phaser 类。在此方法中，当前 phaser 会提前于给定的阶段值到达，

语法

参数

phase - 它到达的阶段编号。

它返回将到达的下一个阶段编号。

示例 1

import java.util.concurrent.Phaser;
public class PhaserAwaitAdvanceExample1
{
    public static void main(String[] args) throws InterruptedException
    {
          Phaser p = new Phaser();
          p.register();
          System.out.println("Phaser Object is register...");
          int pc = p.getPhase();
          System.out.println("Initial Phase count is "+pc);
          new PhaserAwaitAdvanceExample1().test(p); 
         System.out.println("Thread awaitAdvance : "+ p.awaitAdvance(1));
          	
    } 
     private void test(final Phaser p)
    {
        new Thread(){
                @Override
                public void run()
                    {
                        System.out.println(Thread.currentThread().getName()+" arrived"); 
                    }

               }.start();
    }
}

输出

Phaser Object is register...
Initial Phase count is 0
Thread awaitAdvance : 0
Thread-0 arrived

示例 2

import java.util.concurrent.Phaser;
public class PhaserAwaitAdvanceExample2
{
    public static void main(String[] args) throws InterruptedException
    {
          Phaser p = new Phaser();
          p.register();
          System.out.println("Phaser Object is register...");
          for(int i=1; i<=5; i++)
          {
          new PhaserAwaitAdvanceExample2().test(p);
          if(i==3)
          {
           System.out.println("Thread awaitAdvance : "+ p.awaitAdvance(3));
          }
          }
    } 
     private void test(final Phaser p)
    {
        new Thread(){
                @Override
                public void run()
                    {
                        System.out.println(Thread.currentThread().getName()+" arrived");
                         
                    }

               }.start();
    }
}

输出

Phaser Object is register...
Thread-1 arrived
Thread awaitAdvance : 0
Thread-2 arrived
Thread-3 arrived
Thread-0 arrived
Thread-4 arrived
