Java Tutorial | Limiting Chars on JTextField using PlainDocument (Validation)

Показать описание

In this tutorial I look at limiting user input on a JTextField, to achieve this, I had to use PlainDocument to actually get the TEXT on the JTextfield.

I will give the code upon request, also note on 6:48 the output doesn't convert to uppercase I had Caps long on.

Feel free to drop any question on the comment section. :D.

Is it possible to get the code for this?

Monasso

Could I get the code please?
Also if you limit the characters does that mean that JTextField must have that many characters or can it have less. Because i tried doing a JFormattedTextField and the text inside would disappear if it wasn't at the maximum number of characters?
-Thanks in advance

I looked at the code, you done half of the job you just need to link it to GUI interface. First create the JFrame, create two buttons, each openning another JFrame or JPanel for different forms, you set the JFrame layout to flowlayout();, then you will need to create and Label you textfield, a JLabel followed by a JTextfield. then you get the string then apply to the methods you created it by instantiating it, I am really curious where your storing these stuff ???? Like into a file.
