java - 在Java中以不同的间隔运行多个Timer任务

Question

说我有以下代码

 Timer t1 = new Timer();
 t1.scheduleAtFixedRate(new TimerTask() {
        @Override
         public void run(){
             //TASK 1
         }
 },0,2000);

 Timer t2 = new Timer();
 t2.scheduleAtFixedRate(new TimerTask() {
        @Override
         public void run(){
             //TASK 2
         }
 },0,180000);

Task1和Task2是否会彼此独立运行，还是将Task2推迟30分钟？

如果发生后者，将其拆分为两个线程是否是唯一的选择？

Answer 1

从Javadoc of Timer:

Corresponding to each Timer object is a single background thread that is used to execute all of the timer's tasks, sequentially.

您的每个Timer实例将独立执行。
