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 stubPig 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 blocke.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 blocke.printStackTrace();}res += (++times);System.out.println("now is:" + res);if (times == n) {System.out.println("res is:" + res);break;}}}}

执行结果:
