[FIXED] Use of super in Comparator in java

Issue

I understand in

Comparator < ? super T> comp

it returns the maximum element of the given collection, according to the order defined by the specified comparator. But I don't understand the purpose of the

super T

Could anyone possibly explain?

Solution

In here < ? super T> means generics - NOT comparisons.

It means you have a Comparator with a generic type of ? super T (something that extends is super typed by T), as explained in this thread

comp is the variable name (binding).

So basically in here Comparator < ? super T> is a type and comp is an identifier (variable name), that is of type Comparator <? super T>
