问题描述
我的问题很简单:
编译器是否将最终类中的所有方法都视为最终方法?给final类的方法加上final关键字有什么作用吗?
My question is pretty simple:
Does the compiler treat all the methods in a final class as being final themselves? Does adding the final keyword to methods in a final class has any effect?
我知道 final 方法有更好的内联机会，这就是我问的原因.
I understood that final methods have a better chance of getting inlined and this is why I am asking.
提前致谢.
推荐答案
你说得对，final类中的所有方法都是隐式final的.
You're correct, all methods in a final class are implicitly final.
见这里:
"请注意，您还可以声明整个类 final.声明的 final 不能被子类化.这特别有用，因为例如，在创建像 String 类这样的不可变类时."
"Note that you can also declare an entire class final. A class that is declared final cannot be subclassed. This is particularly useful, for example, when creating an immutable class like the String class."
这里:
final 类中的所有方法都是隐式 final.
All methods in a final class are implicitly final.
