public class ThreadA extends  Thread{
    private int count =0;
    public int getCount() {
        return count;
    }
    @Override
    public void run() {
        super.run();
        while(true) {
            count++;
        }
    }
}

package com.cky.prioritydemo;

public class ThreadB extends Thread{
    private int count =0;
    public int getCount() {
        return count;
    }
    @Override
    public void run() {
        super.run();
        while(true) {
            count++;
        }
    }
}
