### Question:
AccountState implements Serializable { public BigInteger getNonce() { return nonce; } AccountState(AccountAddress address);  AccountState(BigInteger nonce, BigInteger balance, AccountAddress address);  AccountState(AccountState source); BigInteger getNonce(); void setNonce(BigInteger nonce); BigInteger getBalance(); void setBalance(BigInteger balance); BigInteger addToBalance(BigInteger value); AccountAddress getAddress(); @Override String toString();  }### Answer:
@Test public void testAccountStateConstructorWithCorrectNonce() { AccountState accountState = new AccountState(BigInteger.valueOf(1), BigInteger.valueOf(2), AccountAddress.EMPTY_ADDRESS); Assert.assertTrue(accountState.getNonce().longValue() == 1); }
