Thread: 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);
}

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.

I wouldnt know how to do it else, could you give me an example then? XD
