// These arrays will have the same hash-code.
String[] example1 = {"a", "b", "c"}; // Hash: 126145
String[] example2 = {"a", "b", "c"}; // Hash: 126145

// These arrays will NOT have the same hash-code.
String[] example1 = {"a", "b", "c"}; // Hash: 126145
String[] example2 = {"aa", "b", "c"}; // Hash: 3015872
