使用java怎么实现一个多线程的交替打印-创新互联

今天就跟大家聊聊有关使用java怎么实现一个多线程的交替打印，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

notify+wait实现

import org.junit.Test;
import java.util.concurrent.*;

public class TestThreadLocal {
 Object o = new Object();
 CountDownLatch c=new CountDownLatch(2);
 @Test
 public void vvvvvvvv() throws InterruptedException {
  Thread t1 = new Thread() {
   @Override
   public void run() {
    for (int i = 0; i < 26; i++) {
     synchronized (o) {
      System.out.print((char) (65 + i));
      o.notify();
      try {
       if(i<25)o.wait();
      } catch (InterruptedException e) {
       e.printStackTrace();
      }
     }
    }
    c.countDown();
   }
  };
  Thread t2 = new Thread() {
   @Override
   public void run() {
    for (int i = 0; i < 26; i++) {
     synchronized (o) {
      System.out.print(1 + i);
      o.notify();
      try {
       if(i<25)o.wait();
      } catch (InterruptedException e) {
       e.printStackTrace();
      }
     }
    }
    c.countDown();
   }
  };
  t1.start();
  t2.start();
  //t1.join();
  //t2.join();
  c.await();
 }
}
