hi, I appreciate if anyone can help me.

So far this what i got.
I want to limit the length of inputted values into a textfield up to 7 digits.

With this code, the inputted values goes on and on. it is not limiting it to only 7. Only what is displayed, thAt it will show 7 digits. When sum button is click. it adds up all the digits inputted.

What I want is that, I can input up tp 7 digits only.

THANKS

private void jButtonSubtractActionPerformed(java.awt.event.ActionEvent evt) {                                                
        // TODO add your handling code here:

         double A;
         double B;
         int MAX_LEN = 7;

          try {
            A = Double.parseDouble(
                this.jTextField1.getText());

            if(jTextField1.getText().length() > MAX_LEN);
            {
            jTextField1.setText(jTextField1.getText().substring(0, MAX_LEN ));
}
}

you can use a JFormattedTextField in conjunction with a MaskFormatter
