Java generic classes and generic methods

The Java programming idea says:

A generic class is applied across a class, but it can include a parameterized method in the class, and the class can be generic or not generic, that is, whether there is a generic method that has no relation to whether the class in which it resides is a generic class.

A generic method is a method that can be changed independently of a class, which is a basic guideline: whenever you can do it, you should try to use a generic method, that is, if generics are used instead of the entire class, you should use only generic methods. Because it can make things clearer. Also, for a static method, you cannot access a generic type parameter, and all, if the STATICFANGFA needs to use generic capabilities, it must be made a generic method.
