java - 在某些情况下，计数器为负值。为什么？以及如何解决这个问题？

Question

package threadapps;

public class Threads extends javax.realtime.RealtimeThread{

    /**
     * @param args the command line arguments
     */
    static volatile  boolean stop = false;
    public static void main(String[] args) throws InterruptedException {

        // TODO code application logic here
        //
        Thread a = new Threads();
        Thread b = new Threads();
        //set priority for threads
        a.setPriority(4);
        b.setPriority(6);
        //run threads
        a.start();
        b.start();
        //Sleep Thread
        Threads.sleep(5000);
        stop = true;
    }

    @Override
    public void run(){
        // for loop for counting to 10
        //for(int i = 0; i<10;i++){
        //    System.out.println( Thread.currentThread().getName()+" The Counter Is "+i);
        //}    
        int count = 0;
        for(;!stop;)
            count++;
        System.out.println(Thread.currentThread().getName()+" The Count is "+count);
    }
}

运行此代码并查看结果。在某些情况下它可以是负数吗？

Answer 1

如果计数达到 Integer.MAX_VALUE，那么在下一个增量时，它将是 Integer.MIN_VALUE。
