  • java
  • macbook pro
  • mac

本人17款13.3 ,16G 256G跑以下代码风扇声音超级大,有一样配置的吗?而且为何
别人12款mac跑都不卡,是不是哪里配置有问题?求大佬解决。代码如下。

 public class ThreadTest {
    private static final long count = 10000001;
    public static void main(String[] args) throws InterruptedException {

        //concurrency();
        serial();
    }

    private static void serial() {
        long start = System.currentTimeMillis();
        int a = 0;
        for (int i = 0; i < count; i++) {
            a += 5;
            System.out.println("a:" + a);
        }

        int b = 0;
        for (long i = 0; i < count; i++) {
            b -= 1;
            System.out.println("b:" + b);
        }
        long time = System.currentTimeMillis();
        System.out.println("concurrency:" + (time - start) + "\t" + "b:" + b);
    }

    private static void concurrency() throws InterruptedException {
        long start = System.currentTimeMillis();

        Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {
                int a = 0;
                for (int i = 0; i < count; i++) {
                    a += 5;
                    System.out.println("a:" + a);
                }
            }
        });
        thread.start();
        int b = 0;
        for (long i = 0; i < count; i++) {
            b -= 1;
            System.out.println("b:" + b);
        }
        thread.join();
        long time = System.currentTimeMillis();
        System.out.println("concurrency:" + (time - start) + "\t" + "b:" + b);
    }

}
