### Question:
SecureKey implements Serializable, Loggeable { public void setKeyBytes (byte[] keyBytes) { this.keyBytes = keyBytes; }  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 testSetKeyBytes() throws Throwable { byte[] keyBytes = new byte[3]; SecureKey secureDESKey = new SecureDESKey((short) 100, "testSecureKeyKeyType", keyBytes, keyBytes); secureDESKey.setKeyBytes(keyBytes); assertSame(keyBytes, ((SecureDESKey) secureDESKey).keyBytes, "(SecureDESKey) secureDESKey.keyBytes"); }
