方法不是Java中的第一类对象，因此它们不能作为参数传递。您可以在一个烦人的类中使用wrap方法调用，例如 Runnable 界面：

Methods aren't first-class objects in Java, so they can't be passed as parameters. You could use wrap your method call in an annoymous class that extends e.g. the Runnable interface:

private void MeasureExecutionTime(Runnable r) {
    r.run();
}

...


MeasureExecutionTime(new Runnable() { public void run() { m(); } });
