I cannot seem to retrieve the values from each of the fields created. I currently in my actionPerformed()
method have f
set to 1, but I would like to retrieve the values from all the created fields. It may be the case that not all fields are used.
Please see code below
package classes;
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
public class Classes extends JFrame implements ActionListener {
private JTextField ivol, fvol;
private JLabel ilabel, flabel;
private JButton button;
private final JTextField vol1HH[] = new JTextField[10];
private final JLabel vollabel[] = new JLabel[10];
private int f;
public static void main(String[] args) {
Classes RV = new Classes();
RV.setSize(1000, 1200);
RV.createGUI();
RV.setVisible(true);
double sum = add((double) 10, (double) 20.1, (double) 30.1, (double) 40.1);
System.out.println(sum);
}
public static int add(Double... numbers) {
int result = 0;
for (Double number : numbers) {
result += number;
}
return result;
}
public void createGUI() {
setDefaultCloseOperation(EXIT_ON_CLOSE);
Container window = getContentPane();
window.setLayout(null);
ivol = new JTextField(20);
ivol.setBounds(150, 50, 100, 20);
fvol = new JTextField(20);
fvol.setBounds(150, 1000, 100, 20);
ilabel = new JLabel("Initial Order Volume");
ilabel.setBounds(10, 50, 150, 20);
flabel = new JLabel("Final Order Volume");
flabel.setBounds(10, 1000, 150, 20);
button = new JButton("Remaning Volume");
button.setBounds(10, 1050, 150, 20);
button.addActionListener(this);
window.add(ivol);
window.add(fvol);
window.add(ilabel);
window.add(flabel);
window.add(button);
for (int y = 100; y < 1000; y += 50) {
for (int f = 0; f < 10; f++) {
vol1HH[f] = new JTextField(10);
vol1HH[f].setName("volHH" + f);
vollabel[f] = new JLabel("HH34");
vol1HH[f].setBounds(150, y, 100, 20);
vollabel[f].setBounds(80, y, 100, 20);
window.add(vol1HH[f]);
window.add(vollabel[f]);
}
}
}
@Override
public void actionPerformed(ActionEvent e) {
//double vol;
f = 1;
double vol = Double.parseDouble(vol1HH[f].getText());
//if(e.getSource() == button) {
fvol.setText(Double.toString(vol));
}
}
If you want to retrieve all records from textfields and store it some where. You need to have a variable for storing.
Now, simply create a method to transfer all input be it empty of filled into the
fieldRecords[]
.When ever you need to retrieve your records, simply call
retrieve()
. For example when you press the button - hence you can place it in theactionPerformed()
.With the data saved into the array. You can print it or set it back onto the textfields any time you need.
Example:
