### Question:
EncryptedPIN implements Serializable, Loggeable { public void setPINBlock (byte[] pinBlock) { this.pinBlock = pinBlock; } EncryptedPIN();  EncryptedPIN(byte[] pinBlock, byte pinBlockFormat, String accountNumber);  EncryptedPIN(byte[] pinBlock, byte pinBlockFormat, String accountNumber, boolean extract);  EncryptedPIN(String pinBlockHexString, byte pinBlockFormat, String accountNumber);  EncryptedPIN(String pinBlockHexString, byte pinBlockFormat, String accountNumber, boolean extract); void dump(PrintStream p, String indent); void setPINBlock(byte[] pinBlock); byte[] getPINBlock(); void setPINBlockFormat(byte pinBlockFormat); byte getPINBlockFormat(); void setAccountNumber(String extractedAccountNumber); String getAccountNumber(); static String extractAccountNumberPart(String accountNumber);  }### Answer:
@Test public void testSetPINBlock() throws Throwable { byte[] pinBlock = new byte[3]; EncryptedPIN encryptedPIN = new EncryptedPIN(pinBlock, (byte) 0, "testEncryptedPINAccountNumber"); byte[] pinBlock2 = new byte[0]; encryptedPIN.setPINBlock(pinBlock2); assertSame(pinBlock2, encryptedPIN.pinBlock, "encryptedPIN.pinBlock"); }
