Short Answer: You can't.

Long Answer: You can, but it's a little different.

First sort your array.
Java:
Arrays.sort(array);

Second use binarySearch.
Java:
int index = Arrays.binarySearch(array, "somevalue");

Or you could use Arrays.asList to get a List and then call that list's indexOf method.
