Dear sir or madam, How can I decrypt data from database that use MD5 in Netbeans 8.0.2, Please to help me !

You can't.
MD5 is not an encryption algorithm - it is a hashing algorithm.
The major difference is that an encryption algorithm like DES can be reversed to regenerate the original input if you have the correct key, while a hashing algorithm like MD5 or SHA cannot: it throws away information to generate the hashed value. That is why it is used for password storage: because you don't need to reverse it in order to verify a password input.

And although MD5 is officially "broken" and should not be used for new projects, that just means that you can in some cases generate an enterable sequence from the hashed value - not the original input but ones that will generate the same hash.
