Question

I have been using the “Learning Java 2nd Edtion” book to try make my java application write my input to a text file called properties. I have manipulated the text book example into my own code but still having problems trying to get it to work. I think i may need to hook it up to my submit button but this wasnt mentioned within the chapter.

Basically im trying to store the information in the text file and then use that text file within another location to read all of the property details.

Here is my code for the AddProperty Page so far any advice would be greatly appreciated.
At the moment iv hit the wall.

Answer 1

in your Action performed you are not stating anything, for example in your action performed you could add.

   public void actionPerformed(ActionEvent e)
            {

              houseNumber2 = houseNumber1.getText();
              housePrice2 = housePrice1.getText();
              town1 = town.getText();
              comboBoxType2 = comboBoxType1.getSelectedItem();


            inputData = housenumber2 + "," + housePrice2 + "," + town1 + "," + comboBoxType2;
             FileName.Filewritermethod(inputData);
             frame.setVisible(false);

            }
       });

This would strings to take the values of your JTexFields and pass them onto a textfile provided you have a FileWriter Class
