整数不会设置为JTextField

Question

I'm having problems in my program. Well, here's my code:

    JButton btnAdd = new JButton("Add");
    btnAdd.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent arg0) { 
            try{
                String query = "INSERT INTO GuestList (id, Title, FirstName, MiddleName, LastName, Address, ContactNo, Occupation) values (?, ?, ?, ?, ?, ?, ?, ?)";
                PreparedStatement pst = conn.prepareStatement(query);
                count++;

                pst.setString(1, String.valueOf(textField.setText(count + "")); //<<--This is my problem
                pst.setString(2, comboBox.getToolTipText());
                pst.setString(3, fNameTextField.getText());
                pst.setString(4, mNameTextField.getText());
                pst.setString(5, lNameTextField.getText());
                pst.setString(6, addressTextPane.getText());
                pst.setString(7, contactNoTextField.getText());
                pst.setString(8, occupationTextField.getText());
                pst.execute();

                JOptionPane.showMessageDialog(null, "Data Saved!");

                pst.close();

            }catch(Exception e){

            }

        }
    });

I'm having an auto increment in the line that has a comment in it. It says that " - Syntax error, insert ")" to complete Expression" and "The method valueOf(Object) in the type String is not applicable for the arguments (void)"

What should I do to get rid of these? Can someone help me? Thank you. :)

Answer 1

for every opening group like this ( you will need a closing one like that )

you have here 3 open and 2 closed....

 pst.setString(1, String.valueOf(textField.setText(count + ""));

so you are missing one )

try:

pst.setString(1, String.valueOf(textField.setText(count + "")));
