1.定时任务定义:new一个定时器,定时器里面再new一个定时任务

new Timer().schedule(new TimerTask(){ @Override public void run() { System.out.println("bombing!"); } },1000);//1S以后炸,之后每间隔2S炸一次。
2.设置定时炸弹:先炸2s、再炸4s、炸2s、炸4s。。。循环交替

package com.test.timerTask; import java.util.Date; import java.util.Timer; import java.util.TimerTask; public class TimerTaskTest { private static int count =0; public static void main(String[] args) { class MyTimerTask extends TimerTask{ @Override public void run() { count =(count+1)%2; System.out.println("bombing!"); new Timer().schedule(new MyTimerTask(), 2000+2000*count); } } new Timer().schedule(new MyTimerTask(), 2000); //秒钟计时 while(true){ System.out.println(new Date().getSeconds()); try { Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } } } }
