There are no standard methods to search for a particular element in an unsorted array, but there are methods to search a sorted array. Alternatively you could convert the array to a List<String> using java.util.Arrays.asList() and use the List.contains() method. Or you could write your own linear search method.
Some problems are so complex that you have to be highly intelligent and well informed just to be undecided about them. - Laurence J. Peter
