Java学习：线程基础（二）

两个线程交叉运行

案例：编写一个程序，该程序可以接受一个整数n，创建两个线程，一个线程计算从1+...+n并输出结果，另一个线程每隔一秒在控制台输出一句话。这两个工作要同时进行。

代码：

public class TwoThread { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub Pig pig = new Pig(); Bird brid = new Bird(10); Thread t1 = new Thread(pig); Thread t2 = new Thread(brid); t1.start(); t2.start(); } } class Pig implements Runnable { int n = 0; int times = 0; public void run() { while (true) { try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } times++; System.out.println("hello" + times); if (times == 10) { break; } } } } class Bird implements Runnable { int n = 0; int res = 0; int times = 0; public Bird(int n) { this.n = n; } public void run() { while (true) { try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } res += (++times); System.out.println("now is:" + res); if (times == n) { System.out.println("res is:" + res); break; } } } }

执行结果：
