Java generics name clash , has the same erasure

Question

I have superclass Foo. And a class Bar extending it.

public class Bar extends Foo

Function in Foo:

protected void saveAll(C         


        

Answer 1

You just overriding methods with different Signatures.

What will be good idea is to use PECS (Producer - Extends, Consumer - Super) rule described in Effective Java Second Edition by Joshua Bloch.

according to this rule it should looks like this.

In Foo class:

public class Foo{

protected void saveAll(Collection many){....}

protected void getAll(Collection many){....}

}
