★ ★ ☆ ☆ ☆

Binary search runs in logarithmic time in the worst case, making O (log n) comparisons, where n is the number of elements in the array, the O is Big O notation, and log is the logarithm. Binary search takes constant (O (1)) space, meaning that the space taken by the algorithm is the same for any number of elements in the array.

Since the list is small enough to load into memory, sort it and then do a binary search, using the static method java.util.Collections.binarySearch(). This returns an index, and works regardless of whether the exact string is in the list or not (although if it's not it returns a negative number, so be sure to check that).
