Type parameters can also be declared within method and constructor signatures to creategeneric methodsandgeneric constructors. This is similar to declaring a generic type, but the type parameter's scope is limited to the method or constructor in which it's declared. 泛型方法声明: public (static)...
The syntax for a generic method includes a list of type parameters, inside angle brackets, which appears before the method's return type. For static generic methods, the type parameter section must appear before the method's return type 1.Write a Java program to create a generic method that ...
5. Java Generic Method Sometimes we don’t want the whole class to be parameterized, in that case, we can create java generics method. Since theconstructoris a special kind of method, we can use generics type in constructors too. Here is a class showing an example of a java generic met...

(原文:Generic methods allow type parameters to be used to express dependencies among the types of one or more arguments to a method and/or its return type. If there isn’t such a dependency, a generic method should not be used.)

JavaGenericsadd type parameters to classes, interfaces, methods and variables that decide to use them. To be able to use a type parameter with a class, interface, method or variable the type you are trying to add the type parameter to, must be designed to allow generic type parameters. ...
