1.随便选择两个城市作为预选旅游目标。实现两个独立的线程分别显示10次城市名,每次显示后休眠一段随机时间(1000ms以内),哪个先显示完毕,就决定去哪个城市。分别用Runnable接口和Thread类实现。
package Thanqi; public class Chengshi extends Thread { private String city; public Chengshi(String city) { this.city=city; } public void run(){ for(int i =0;i<10;i++) {System.out.println(city); try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO 自动生成的 catch 块 e.printStackTrace(); } } } }
package Thanqi; public class TestCity { public static void main(String[] args) { Chengshi c1= new Chengshi("城市1"); c1.start(); //用新线程调用run方法 Chengshi c2= new Chengshi("城市2"); c2.start(); //用新线程调用run方法 } }
