Generics in Java, Merge method

Question

I have to create a Merge method to merge together two lists (Array-Based Lists). My method works, but now I have to change my method to generics. This is my method without gener

Answer 1

Assuming you have declared <T extends Comparable<T> > at the class level, remove it on the method:

class OrderedArrayList1<T extends Comparable<T> > {
  public OrderedArrayList1<T> merge(OrderedArrayList1<T> list2) {
    ...
  }
}

Otherwise, you're defining a different type variable which just happens to have the same name, hence the slightly cryptic "T cannot be converted to T" message.
