Generic programming means that the code you write can be reused by many different types of objects.Upper bound of generic variable: the upper bound declared by the extends keyword can be either a class or an interface.Generic variable lower bound: the type of a generic parameter that is fixed by the keyword super is a type or other superclass. When a generic variable is declared so, when a generic type is instantiated, it needs to be explicitly typed as the specified upper-bound type or its subc

For example,java explicitly describes the size of each base data type and its operation behavior (these data types are described by Java syntax) 8. High

By reading this book, we will closely combine the design pattern/framework + J2EE practices to realize programming flexibility and predictability. Of course, there are still fewer practical examples in this book, and there are not many books discussing practical applications from the perspective of design patterns and frameworks. Here I will "selfish, my "Java practical system o
