[brisk coyote]

Hello, my "login" button's function doesn't work. I did everything I know and nothing worked.
Here's the code below...

You should only have 1 main method, only one of them runs when starting the program. If the program starts by running the main method in Main.java, logininfo will get set, but the GUI won't show. If the program starts from the main method in LoginFormDemo.java, then the GUI shows, but logininfo stays empty.

I tried putting these:

IDandPasswords idandPasswords = new IDandPasswords();
LoginFormDemo loginPage = new LoginFormDemo(idandPasswords.getLoginInfo());

into LoginFormDemo and deleted the main class, still the button didn't worked.

Or rather I'm doing not right?

[keen gulch]

If you only pasted those lines in, loginPage is never used, and frame is instead.
Are you familiar with OOP? Each object of the same class can have different data, in other words, the value of logininfo will be set inside of loginPage, but it will be empty inside of frame

[brisk coyote]

Yes I am familiar, but it's too much for me to remember all the things I studied that's why I'm having this trouble.

[keen gulch]

I feel you, it takes a while to get down.

[brisk coyote]

Like ,I know the things that I studied. But when I'm going to apply them to the actual thing my mind goes blank.

[keen gulch]

I think for me, applying information is probably the quickest way to learn it

[brisk coyote]

I agree, I also learned something in java swing the first time I used it few days ago while making this log in form.

And still can't figure out how can I make the button work.

[keen gulch]

can you share your main method?

[brisk coyote]

Which one? from the main class or the LoginFormDemo?

The first one is for the LoginFormDemo

[keen gulch]

did you understand what I wrote in this message? The whole project should only have 1 main method.

[brisk coyote]

Yeah, but they are on a separate class and tried to remove the main class on the 'Main.class'

that's what I've been trying to do earlier

Already tried removing the main in the main.java

[brisk coyote]

There's nothing wrong with my button's function right?

[keen gulch]

I see.
The button will work, though it won't display anything if an incorrect username is inputted.

Provided that logininfo is set

[brisk coyote]

This is my main method now, pfff

[keen gulch]

why are you making 2 LoginFormDemo objects?

These vids might help to understand oop better:

The constructor video gives a good OOP example

[brisk coyote]

This one is pre-coded, the 2 at the bottom I just pasted it from the java.main

[keen gulch]

well, inside the frame object, logininfo is empty, then the frame object displays from frame.setVisible(true);

I guess I'm good for now, I'll take a rest. Thank you for your assistance. 🙂 I'm closing this thread.
