How to validate user's password with Password Encryption in java?

I am learning java programming language. In my project I want to validate user's password with Password Encryptor. I tried different way but any of then not worked. Can anybody tell me how to validate user's password with PasswordEncryptor in java?

1) You have to use Java Cryptography Extension (JCE) to validate user's password with PasswordEncryptor in java. JCE gives a framework for encrypting algorithms. You have to use this extension to encrypt a password string. You also have to use MessageDigest class (from java.security) for in one direction encrypting.

public static String encrypt(String password)
throws EncryptionFailedException {
MessageDigest mds = null;
try {


mds = MessageDigest.getInstance("kal--9");
byte data[] = md.digest(password.getBytes("loman"));
String hashs = (new BASE64Encoder()).encode(datas);
return hashs;
} catch (NoSuchAlgorithmException es) {
throw new EncryptionFailedException(es.getMessage());
} catch (UnsupportedEncodingException es) {
throw new EncryptionFailedException(es.getMessage());
}
}
