传统定时器技术回顾(jdk1.5以前)
public class TraditionalTimerTest { static int count = 0; public static void main(String[] args) { //10秒后开始执行,每隔3秒执行一次 new Timer().schedule(new TimerTask() { @Override public void run() { System.out.println("bombing..."); } }, 10000,3000); /** * 需求:2秒,4秒间隔执行定时任务 */ 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); while(true){ try { System.out.println(new Date().getSeconds()); Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } //quartz 周一~周五执行任务,周六日不执行 } }
