Help needed to extract a value from Textfield

Question

Hi,
I am new to AWT prgramming .
I have created a menu called " Menu System Test window " and it contains toplevel menu item "File" and File Menu contains subitems "Product Evaluation" and "Exit".
When i click File->Product Evaluation it displays a new Frame named "ProductEvaluationMeasurementTool" with some check boxes ,radiobuttons, buttons , text fields.
After compiling the program if i check some check boxes and radiobuttons and press Button1 it displays the result as no of checkboxes checked divided by total no of checkboxes(which i have declared as 18 in my code) in textField1.
I also have textField2 for entering user input.
now my question is after compiling program i check some checkboxes , enter some value in textField2 and press Button2. The result should be diplayed as no of checkboxes checked plus the value added in textField2 divided by total no of checkboxes(which is 18 in my code) . This result should be displayed in textField3.
Can anyone help me?
Thanks in advance
i am sending my code.

Answer 1

            // The result should be diplayed as
            // no of checkboxes checked                 ->           numChecked
            // plus the value added in textField2       ->           input
            double input = Double.parseDouble(textField3.getText());
            // divided by total no of checkboxes       ->            numOfCheckBoxes
            double ratio = (numChecked + input) / (double) numOfCheckBoxes;
            // This result should be displayed in textField3
            this.textField2.setText(Double.toString(ratio));
