java - 在Java中退出我自己的线程

Question

好的，我下面有以下代码

public static void StartDayProcessor(){
        new Thread(new Runnable() {
            public void run() {
                long lastSec = 0;
                while(DayProcessor.isDayProcessorActive){
                    long sec = System.currentTimeMillis() / 1000;
                    if (sec != lastSec) {
                        DayProcessor.secondsActive++;
                        DayProcessor.timeLeftInSecs = DayProcessor.day.getTimeLimitInSecs() - DayProcessor.secondsActive;
                        System.out.println("Seconds left for this day: " + DayProcessor.timeLeftInSecs);
                        if(DayProcessor.timeLeftInSecs == 0){
                            DayProcessor.isDayProcessorActive = false;
                            break;
                            //exit my own thread here!!
                        }
                    }
                }

            }
        });
    }

上面的代码位于我更大的代码中，但我想知道如何通过在线程本身内部运行代码来停止线程运行。我怎样才能阻止它？

停止线程的两种方法，一种是您已经通过条件逻辑和 break/return 使用的方法:

DayProcessor.isDayProcessorActive = false;
break;//return;

另一种方法是使用中断:

while(!Thread.currentThread.isInterrupted()) {
     ... logic
     if(condition) {
         Thread.interrupt();
     }
}
