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

At runtime, the parameter types are replaced by Object. So saveAll(Collection) and saveAll(Collection) are transformed to saveAll(Collection). This is a name clash. Look here for details.

You could do this :

public class Foo {
    protected void saveAll(Collection many) {
        // do stuff
    }
}

public class Bar extends Foo {
}
