in a previous java tutorial we did a login and register form design ( video link:    • JAVA - How To Design Login And Regist...   ),
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 here:    • Java - How To Connect Java To MySQL D...  
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
