theComparableinterface. (The natural ordering is the ordering imposed by the objects' owncompareTomethod.) This enables a simple idiom for sorting (or maintaining) collections (or arrays) of objects that implement theComparableinterface in reverse-natural-order. For example, supposeais an array of...
