    Default Writing an Action Event in a Jpanel to convert user text entered in a textField to uppercase

    I'm trying to figure how to write an ActionEvent for a Radio Button to convert text entered in a text field to uppercase. I'm lost on where to begin. Do I need to get or set something?

    private void convertUpperActionPerformed(java.awt.event.ActionEvent evt) {
            convertUpper.s
        }

    you have to make a JFrame first with a text field

    If you want the text automaticly changed to uppercase.
    you should put this code in a loop(could be in the main).
    String text;
     
    while(){
          text = textfield.getText();
          text.toUpperCase();
          textfield.setText(text);
    }

    @The_pizzaguy what does that code do when compiled and executed?
    It doesn't compile and could be a useless, endless loop if it did.
    If you don't understand my answer, don't ignore it, ask a question.

    It is just an example, and the while loop used in my last comment could be the main update loop.
    If that loop is running it will auto update the code to uppercase.

    Endless loops like that are usually a big waste of resources.

    Why post junky code?

    There are listeners and documents that can be used to control data in a text field.

    Don't post junky code.
