java – 为什么添加throws InterruptedException会为Runnable的

参见英文答案 > Is there a way to make Runnable’s run() throw an exception?????????????????????????????????????9个
为什么在下面的代码“public void run()throws InterruptedException”创建一个编译错误,但“public void run()抛出RuntimeException”不？

InterruptedException引发的编译错误是“Exception InterruptedException与Runnable.run()中的throws子句不兼容”

是因为RuntimeException是未经检查的异常,因此不会更改run()签名吗？

public class MyThread implements Runnable{
String name;
public MyThread(String name){
    this.name = name;
}
@Override
public void run() throws RuntimeException{
    for (int i = 0; i < 10; i++) {
        try {
            Thread.sleep(Math.round(100*Math.random()));
            System.out.println(i+" "+name);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}


public static void main(String[] args) {
    Thread thread1 = new Thread (new MyThread("Jay"));
    Thread thread2 = new Thread (new MyThread("John"));
    thread1.start();
    thread2.start();

}

}
