### Question:
WalletUtil { public static ECKey generateWallet(String walletPath){ return generateWallet(walletPath,null); }  static ECKey generateECKey(); static ECKey generateWallet(String walletPath); static ECKey generateWallet(String walletPath,String walletName); static ECKey loadWallet(String walletUrl); static byte[] sign(byte[] messageHash,ECKey ecKey); static byte[] sign(byte[] messageHash,byte chainId, ECKey ecKey); static ECKey.ECDSASignature signature(byte[] messageHash, ECKey ecKey); static boolean verify(byte[] messageHash, byte[] signature, byte[] address); static byte[] signatureToAddress(byte[] messageHash, String signatureBase64); static byte[] signatureToAddress(byte[] messageHash, byte[] signature); static byte[] signatureToAddress(byte[] messageHash, ECKey.ECDSASignature signature); static byte[] signatureToPubKeyBytes(byte[] messageHash, byte[] signatureEncoded); static byte[] computeAddress(byte[] pubBytes); static byte[] signToByteArray(ECKey.ECDSASignature signature); static ECKey.ECDSASignature signToECDSASignature(byte[] signatureByteArray); static byte[] encrypt(byte[] message,byte[] publicKey); static byte[] encrypt(byte[] message,ECKey ecKey); static byte[] decrypt(byte[] encryptMessage,ECKey ecKey);  }### Answer:
@Test @Ignore public void generateWallet() { logger.info("walletFilePath:{}", walletFilePath); ECKey ecKey = WalletUtil.generateWallet(walletFilePath); logECKey(ecKey); Assert.assertNotNull(ecKey); }
