If you are watching this in 2020, the *passwordField* object now uses the *"getPassword()"* function.
Not only that, but eclipse will not accept the command below, as the *getPassword()* function does not return an argument that is acceptable to the *setString()* function:
*"pstQuery.setString(2, passwordField.getPassword());"*
I was able to get mine to work by using teh following line of code:
*"pstQuery.setString(2, new String(passwordField.getPassword() ) );"*
Please note two things, I am learning to use eclipse with mySQLWorkbench. This is relevant for two reasons:
1) I'm doing a customized Connection that differs from the tutorial, and makes use of a local SQL server on my laptop, instead of SQLite.
2) As I am learning to create a Java program that connects to MySQL WorkBench, I am not learning to design a real-world program that would feature all the relevant security.
If you are using this tutorial to do anything remotely professional, you want to *SALT* your passwordField, and use cryptographic functionality to keep it from being passed as clear text. This secures the password entry so that it is no longer easily accessible/readable by individuals with malign intentions.
do you have a playlist with all those videos ? or could you post the code on some site ?
Great tutorial. The Login Window helped a lot. I have a question though, how do I welcome the user by his full name that logged in, on a new Frame, using a JLabel?
+Jenaya Joseph Create an empty frame and add a JLabel on top of it.Once the user logs in, assign the username to the empty JLabel. Open that frame.
sir can you make a register tutorial with this? i really need the register
friends if you want to directly login without database connection that is the code for login i followed this code.
String uname=textFieldUN.getText();
String psf=passwordField .getText();
if(uname.equals("jenny") && psf.equals("abccba")){
JOptionPane.showMessageDialog(frame,"Successfully login");
}else{
JOptionPane.showMessageDialog(frame,"user name or password is invalid");
}
}
HAHAHA
Thank you for teaching other how to program and thank you for the way of how you explain . But what i think is the beginner of java programming should start to create their own class by coding without dragging and dropping as a result they can easily move to learn OOP in java and aware of the need of reusing the class

Put the Sqlite file in the path
did you fix it, coz mine still doesn't work even after I put the JAR files in
Bruh I'm still struggling you figure it out ?
how do i get it work with .getPassword instead of .getText ? if i use getPassword i get errors about the getString
why don't you just use .getText on the password field, it's gonna give you the string they enter as the password
