自我界定的泛型 [英] Self bounded generics

问题描述

这些泛型之间是否有实际的区别

  public class SelfBounded< T extends SelfBounded< T>> {} 
  

和这一个

  public class SelfBounded< T extends SelfBounded> {} 
  

？

如果是，那我该如何观察它们？

解决方案

这里已经有很多类似的问题。
您可以阅读以下文章

或者下列问题：

• Java枚举定义




• 会有什么不同在Java中，如果枚举声明没有递归部分

Is there is any actual difference between these this generic

public class SelfBounded <T extends SelfBounded<T>>{}

and this one

public class SelfBounded <T extends SelfBounded>{}  

?

If yes, then how can I observe them?

解决方案

There are a lot of similar questions here already. You can read the following article

Or the following questions:

• Java Enum definition
• Why in java enum is declared as Enum<E extends Enum<E>>
• What would be different in Java if Enum declaration didn't have the recursive part
