java 线程的优先级的设置的测试

线程的优先级，默认的是5，

最大的优先级是10

最小的优先级是1

我们测试将后执行的thread1优先级设置为10，先执行的thread2优先级设置为1，最后得出结果，优先级高thread1的获取cpu的机会更大，例如优先级为10的thread1的线程执行到了第3306665次了，thread2才执行到1014520次，几乎是thread2的执行的3倍的速度

        Thread thread1 = new Thread(new Runnable() {
            @Override
            public void run() {
                for (int i = 0; i < 10000000; i++) {
                    Log.d("kodulf", "thread1"+"  "+i);
                }
            }
        });
        Thread thread2 = new Thread(new Runnable() {
            @Override
            public void run() {
                for (int i = 0; i < 10000000; i++) {
                    Log.d("kodulf", "thread2"+"  "+i);
                }
            }
        });

        thread2.setPriority(1);
        thread2.start();
        thread1.setPriority(10);
        thread1.start();

D/kodulf: thread2  1014519
D/kodulf: thread1  3306664
D/kodulf: thread2  1014520
