Java get String CompareTo as a comparator object

I would like to sort and binary search a static array of strings via the String.CompareTo comparator.

The problem is that both sorting, and binary searching requires that a Comparator object be passed in -- So how do I pass in the built in string comparator?

Answer

The Arrays class has versions of sort() and binarySearch() which don't require a Comparator. For example, you can use the version of Arrays.sort() which just takes an array of objects.
