Sometimes we need to determine whether a class implements an interface (Interface), such as when using the reflection mechanism (Reflection) to find a particular type.In simple terms, you can use the Type.isassignablefrom method: 12

 Generics are a feature of high-level programming languages. The introduction of generics has improved the efficiency of program development, and the reuse of code has been greatly improved. With generics, we can create classes and methods that
