How to compare multiple strings? [duplicate]

Answer 1

String[] options = {"a", "b"}; // Must be sorted.
if (java.util.Arrays.binarySearch(options, question) < 0) {
  System.out.println("Sorry that isn't an A or a B");
}

Alternatively (assuming your strings don't contain |:

if ("a|b".indexOf(question) == -1) {
  System.out.println("Sorry that isn't an A or a B");
}
