### Question:
WalletUtils { public static String generateFullNewWalletFile(String password, File destinationDirectory) throws NoSuchAlgorithmException, NoSuchProviderException, InvalidAlgorithmParameterException, CipherException, IOException { return generateNewWalletFile(password, destinationDirectory, true); }  static String generateFullNewWalletFile(String password, File destinationDirectory); static String generateLightNewWalletFile(String password, File destinationDirectory); static String generateNewWalletFile(String password, File destinationDirectory); static String generateNewWalletFile(
            String password, File destinationDirectory, boolean useFullScrypt); static String generateWalletFile(
            String password, ECKeyPair ecKeyPair, File destinationDirectory, boolean useFullScrypt); static Bip39Wallet generateBip39Wallet(String password, File destinationDirectory); static Credentials loadCredentials(String password, String source); static Credentials loadCredentials(String password, File source); static Credentials loadBip39Credentials(String password, String mnemonic); static String getDefaultKeyDirectory(); static String getTestnetKeyDirectory(); static String getMainnetKeyDirectory(); static boolean isValidPrivateKey(String privateKey); static boolean isValidAddress(String input);  }### Answer:
@Test public void testGenerateFullNewWalletFile() throws Exception { String fileName = WalletUtils.generateFullNewWalletFile(PASSWORD, tempDir); testGeneratedNewWalletFile(fileName); }
