 Full video link: https://www.youtube.com/watch?v=ZsbgiTR6osA

and in this one will see how to connect the login and signup form with a mysql database

to do that you need to download mysql connector, watch tutorial from 
and add it to your project

we will ceate a class (MyConnection) to connect our login and register forms with mysql database

in the register form wi will create a function (checkUsername) to check if the username you want to register is already exists in the database table

what we will check when the user click on the register button:
- if the username jtextfield is empty
- if the password jtextfield is empty
- if the retype_password text is equal to the password text
- if the username already exists in the database using the "checkUsername" function
- if the jdatechooser is empty

in the login fom it's simple;
the user enter his login and password and click on the login button,

and all we have to do is to check if a user with this username and password already exists on the database, and if the user don't exists show a warning message , else show a new form with the user username displayed on a jlabel.
