java - Thread 类的静态 sleep 方法如何在不访问 'this' 引用的情况下工作？

Question

我对静态方法有些困惑。静态方法无权访问 this 引用。 (在 Java 中，this 是引用当前对象的引用。)

当调用Thread.sleep(millis)时，Thread类的静态sleep方法是如何选择让哪个线程 hibernate 的？ Thread.sleep(long millis) 是静态方法，无法访问 this 引用。

public class CurrentThreadDemo {
    public static void main(String... args) {

        Thread t = Thread.currentThread();

        System.out.println("Current thread: " + t);

        //change the name of the thread
        t.setName("My thread");
        System.out.println("After name change: " + t);

        try {
            for (int n = 5; n > 0; n--) {
                System.out.println(n);
                Thread.sleep(1000);
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

Answer 1

When there is a call to Thread.sleep(millis), how does the static sleep method of Thread class choose to which thread to sleep.

Thread.sleep 的规范是它挂起当前 线程，即调用sleep 方法的线程。
