### Question:
SecureKey implements Serializable, Loggeable { public void setKeyLength (short keyLength) { this.keyLength = keyLength; }  void setKeyBytes(byte[] keyBytes); byte[] getKeyBytes(); void setKeyCheckValue(byte[] keyCheckValue); byte[] getKeyCheckValue(); void setKeyLength(short keyLength); short getKeyLength(); void setKeyType(String keyType); String getKeyType(); void setScheme(KeyScheme scheme); abstract KeyScheme getScheme(); String getKeyName(); void setKeyName(String keyName);  }### Answer:
@Test public void testSetKeyLength() throws Throwable { byte[] keyBytes = new byte[3]; new SecureDESKey((short) 100, "testSecureKeyKeyType", keyBytes, keyBytes).getKeyBytes(); SecureKey secureDESKey = new SecureDESKey((short) 1000, "testSecureKeyKeyType1", "3check-value>".getBytes(), keyBytes); secureDESKey.setKeyLength((short) 100); assertEquals((short) 100, ((SecureDESKey) secureDESKey).keyLength, "(SecureDESKey) secureDESKey.keyLength"); }
