你将不得不等到一天中的小时大于 15，因为你所有的 output 都发生在else if (hour<=24)的情况下。

或者您可以将 output 移出此代码块：

    } else if(hour<=24) {
        greeting = "Evening";
    } else {
        greeting = "Night";
    }

    System.out.println(" ");
    System.out.println("Good " + greeting + ", " + name);
    System.out.println("are you sure that you're " + age + " years ?" );
    System.out.println("and live on " + address);
