I am trying to get the input that I submit in a JFrame form and store it in an arraylist. I am not sure how to get what input i place in the text field when my ActionEvent occurs. Can anyone tell me how to do it?
my form currently looks like
Here is my code:
public class SpringDemo {
private static void createAndShowGUI() {
final String[] labels = {"Bill: ", "Last Top Up Date: ", "Same Network? "};
int labelsLength = labels.length;
//Create and populate the panel.
JPanel p = new JPanel(new SpringLayout());
for (int i = 0; i < labelsLength; i++) {
JLabel l = new JLabel(labels[i], JLabel.TRAILING);
p.add(l);
JTextField textField = new JTextField(10);
l.setLabelFor(textField);
p.add(textField);
}
JButton button = new JButton("Submit");
p.add(new JLabel());
p.add(button);
//Lay out the panel.
SpringUtilities.makeCompactGrid(p,
labelsLength + 1, 2, //rows, cols
7, 7, //initX, initY
7, 7); //xPad, yPad
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//Execute when button is pressed
System.out.println("Test");
}
});
//Create and set up the window.
JFrame frame = new JFrame("SpringForm");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Set up the content pane.
p.setOpaque(true); //content panes must be opaque
frame.setContentPane(p);
//Display the window.
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}
To do this your createAndShowGUI
method should be like this:
private static void createAndShowGUI() {
final String[] labels = {"Bill: ", "Last Top Up Date: ", "Same Network? "};
int labelsLength = labels.length;
final JTextField[] textField = new JTextField[labels.length];
//Create and populate the panel.
JPanel p = new JPanel(new SpringLayout());
for (int i = 0; i < labelsLength; i++) {
JLabel l = new JLabel(labels[i], JLabel.TRAILING);
p.add(l);
textField[i] = new JTextField(10);
l.setLabelFor(textField[i]);
p.add(textField[i]);
}
JButton button = new JButton("Submit");
p.add(new JLabel());
p.add(button);
//Lay out the panel.
SpringUtilities.makeCompactGrid(p,
labelsLength + 1, 2, //rows, cols
7, 7, //initX, initY
7, 7); //xPad, yPad
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e)
{
for (int i = 0 ; i < labels.length ; i++)
{
System.out.println(labels[i]+"->"+textField[i].getText());
}
}
});
//Create and set up the window.
JFrame frame = new JFrame("SpringForm");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Set up the content pane.
p.setOpaque(true); //content panes must be opaque
frame.setContentPane(p);
//Display the window.
frame.pack();
frame.setVisible(true);
}
