运行结果： 
Fido: Mmmmm, beef 
Fido: Woof Woof 
Fido: Zzzzzzz... 
不停循环。 

如果将sleep替换掉下面那句，程序会报错：sleep() is not applicable for this argument.

Fido: Mmmmm, beef
Fido: Woof Woof
Fido: Zzzzzzz…
以上都说得很清楚了

这是狗的生活 - 编译通过运行结果证明这是一只懒狗 
下面的这个类模拟了一个家庭宠物的生活。main 方法创建了一个 T 实例，用它来表示一只名叫 Fido 的狗，然后让它运行。虽然绝大部分的狗都在后院里奔跑（run），这只狗却是在后台运行（run）。那么，这个程序会打印出什么呢？ 

Java codepublic class T {

    public final String name;
    public final String food;
    public final String sound;
