Returns the maximum element of the given collection, according to the order induced by the specified comparator. All elements in the collection must be mutually comparable by the specified comparator (that is, comp.compare(e1, e2) must not throw a ClassCastException for any elements e1 and e2 in the collection).

This method iterates over the entire collection, hence it requires time proportional to the size of the collection.

Parameters:

<T>     the class of the objects in the collection

coll     the collection whose maximum element is to be determined.

comp     the comparator with which to determine the maximum element. A null value indicates that the elements' natural ordering should be used.

Returns: the maximum element of the given collection, according to the specified comparator.

Exceptions:

ClassCastException if the collection contains elements that are not mutually comparable using the specified comparator.

NoSuchElementException if the collection is empty.

`<T>`		the class of the objects in the collection
`coll`		the collection whose maximum element is to be determined.
`comp`		the comparator with which to determine the maximum element. A `null` value indicates that the elements' natural ordering should be used.

`ClassCastException`		if the collection contains elements that are not mutually comparable using the specified comparator.
`NoSuchElementException`		if the collection is empty.
