### Question:
CipherCryptography { @NonNull public static String createTransformation(@NonNull String algorithmName, @NonNull String mode, @NonNull String padding) { return algorithmName + "/" + mode + "/" + padding; } private  CipherCryptography(); @NonNull static String createTransformation(@NonNull String algorithmName, @NonNull String mode, @NonNull String padding);  }### Answer:
@Test public void testCreateTransformation() { final String transformation = CipherCryptography.createTransformation( CipherCryptography.Algorithm.AES, CipherCryptography.Mode.CBC, CipherCryptography.Padding.PKCS5 ); assertThat(transformation, is("AES/CBC/PKCS5Padding")); }
