Overriding in Java

Question

Is there a way to override a Java method that the only thing that changes is an ArrayList?

For example:

public void quickSortMethod(ArrayList<Integer> comparison, int start, int end)   
{}   

public void quickSortMethod(ArrayList<Double> comparison, int start, int end)   
{}   

This currently gives me the following error:

Method quickSortMethod(ArrayList<Integer>, int, int) has the same erasure quickSortMethod(ArrayList<E>, int, int) as another method in type QuickSort   

Btw I'm using other objects I created as parameters in the ArrayLists

ArrayList<MyObject>...    

Answer 1

In this case you could try making the method itself generic and using that type as the ArrayList type...

public <T> void quickSortMethod(ArrayList<T> comparison, int start, int end)

Answer 2

Unfortunately, no. Because of type erasure after compilation there's no difference between the two.
