Homework - Trouble with inheritance + methods that take in generics

I'm having problems overriding a method from an interface that takes in a generic type.

The code from my interface looks like this:

public interface KDTree<E extends Location> {
...
void insert(E element);
...
}

And for the class:

public class BulkInsertKDTree<E extends Location>
implements KDTree, Iterable {
...
@Override
public void insert(E element) {
//Code
}
...
}

The compiler gives me 2 different errors:

error: BulkInsertKDTree is not abstract and does not override abstract method insert(Location) in KDTree

error: name clash: insert(E#1) in BulkInsertKDTree and insert(E#2) in KDTree have the same erasure, yet neither overrides the other

It seems like the compiler isn't equating the second insert with the first because each one takes in a generic type, and java doesn't recognize that the two are treated the same way. Is there any way I can fix this?

Thanks!

Just a wild guess, but in the interface the method is declared private, while in the implementing class it is declared as public. What happens if you make the access levels equal?
