【Java】线程循环打印

作者:whaon / 发布于2015/8/19/ 340

有三个线程ID分别是A、B、C,请有多线编程实现，在屏幕上循环打印10次ABCABC…


	import java.util.concurrent.Semaphore;
	
	public class TestOderThread {
	
	 private static Semaphore semaphore1 = new Semaphore(0);
	 private static Semaphore semaphore2 = new Semaphore(0);
	 private static Semaphore semaphore3 = new Semaphore(0);
	 public Thread t1;
	 public Thread t2;
	 public Thread t3;
	
	 int count = 10;
	
	 public TestOderThread() {
	 t1 = new Thread() {
	 public void run() {
	 try {
	 semaphore3.release();
	 int i = 0;
	 while(i++ < count) {
	 semaphore3.acquire();
	 System.out.print("A");
	 semaphore1.release();
	 }
	 } catch (Exception e) {
	 e.printStackTrace();
	 }
	 }
	 };
	 t2 = new Thread() {
	 public void run() {
	 try {
	 int i = 0;
	 while(i++ < count) {
	 semaphore1.acquire();
	 System.out.print("B");
	 semaphore2.release();
	 }
	 } catch (InterruptedException e) {
	 e.printStackTrace();
	 }
	 }
	 };
	 t3 = new Thread() {
	 public void run() {
	 try {
	 int i = 0;
	 while(i++ < count) {
	 semaphore2.acquire();
	 System.out.print("C");
	 semaphore3.release();
	 }
	 } catch (InterruptedException e) {
	 e.printStackTrace();
	 }
	 }
	 };
	
	 }
	
	 public void run() {
	 t1.start();
	 t2.start();
	 t3.start();
	 }
	
	 public static void main(String args[]) throws Exception {
	 TestOderThread t = new TestOderThread();
	 t.run();
	 }
	}

试试其它关键字

　线程　　循环打印　

同语言下

可能有用的
