### Question:
EncryptedPIN implements Serializable, Loggeable { public void setPINBlockFormat (byte pinBlockFormat) { this.pinBlockFormat = pinBlockFormat; } 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 testSetPINBlockFormat() throws Throwable { EncryptedPIN encryptedPIN = new EncryptedPIN("testEncryptedPINPinBlockHexString1", (byte) 0, "testEncryptedPINAccountNumber"); encryptedPIN.setPINBlockFormat((byte) 100); assertEquals((byte) 100, encryptedPIN.pinBlockFormat, "encryptedPIN.pinBlockFormat"); }
