I am trying to make a JComboBox for state that is a drop down with all 50 states. How to create an array with all 50 states without having to right all 50 states out(needs to be uneditable?? And a zip JComboBox that is editable.? I have the GUI done but the comboboxes are whats confusing and the array??? any help would be great. Here is what I got so far.
public class personalInfo extends JFrame implements ActionListener { //construct components JComboBox stateCombo = new JComboBox(); JComboBox zipCombo = new JComboBox();
//construct a panel for each row JPanel firstRow = new JPanel(); JPanel secondRow = new JPanel(); JPanel thirdRow = new JPanel(); JPanel fourthRow = new JPanel(); JPanel fifthRow = new JPanel();
//construct a panel for the fields and buttons JPanel fieldPanel = new JPanel(); //JPanel buttonPanel = new JPanel();
//construct labels and text boxes JLabel firstNameLabel = new JLabel("First Name: "); JTextField firstName = new JTextField(10); JLabel lastNameLabel = new JLabel("Last Name: "); JTextField lastName= new JTextField(15); JLabel cityLabel = new JLabel("City: "); JTextField city = new JTextField(10); JLabel stateLabel = new JLabel("State: "); JTextField state = new JTextField(2); JLabel zipLabel = new JLabel("Zip:"); JTextField zip = new JTextField(9);
public static void main(String[] args) { personalInfo f= new personalInfo(); f.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE); f.setSize(350,200); f.setTitle("Personal Information"); f.setResizable(false); f.setLocation(200,200); f.setVisible(true); }
public personalInfo() { Container c = getContentPane(); c.setLayout((new BorderLayout())); fieldPanel.setLayout(new GridLayout(8,1)); FlowLayout rowSetup = new FlowLayout(FlowLayout.LEFT,5,3); firstRow.setLayout(rowSetup); secondRow.setLayout(rowSetup); thirdRow.setLayout(rowSetup); fourthRow.setLayout(rowSetup);
If you don't want to write out all 50 states, you'll need the information from another source. How about storing them in a file, and loading them from there?
Do you know any any other arraylists that are already done? Or is writing them out the only way?
