Class Generics method definition [duplicate]

How do I make the method return type generic? (19 answers)

Closed 8 years ago.

Assuming that you have a lot of classes that extends the class Base.

class Base{}
class A extends Base[}
class B extends Base{}
class C extends Base{}

What must I write so that when I write a get method, I will get the class that I want?

public Base get(Class <? extends Base> clazz, final String key){
 //not important.
}

I want the method to return Objects of class A, B, or C, depending on the input clazz.

Answer 1

public <T extends Base> T get(Class<T> clazz, final String key) {
}

is closer to what you need. Keep in mind that during method declared generic variables, to have more success you typically put the modifiers outside of the parameter list.
