Passing JTextField as String parameter

Hello,

I made a GUI for a simple class that stores accountnumbers and customernames in an arraylist.
In the class I made a public String getAccountNumber(customername), this returns the accountnumber that is linked to a customer with "customername".

In the GUI I made a JTextField where one can provide a customername and a button that triggers the getAccountNumber with parameter: JTextField.getText().
However, it doesn't work with parameter: JTextField.getText(). When I type the name of the customer myself (hardcoded) it does work (???).

Is there something else I have to convert/... to pass the JTextField.getText() to my getter so it returns the result correctly?

Best regards,
Christophe

What is the error you get?

I'm not sure but try: JTextField.getText().toString()

Hi,

The ...toString() doesn't work either.

I am not getting a specific error, it just doesn't find any results and returns the String 'no result found' (which I programmed to do if no matches are found).
I put my code in attachment, feel free to try, maybe one of you guys knows what the problem is. I am quite new at Java (and programming in general).

Best regards,
Christophe

Hello,

I found the solution for this problem.
In my procedure I used this code:

if('string1' == 'string2') {...} => this is wrong since I want to compare the content of the strings, I had to use:

if('string1.equals(string2)) {...} => this is correct, this compares the content of both strings.

That's it.

Best regards,
Christophe
