ItemListener

Question

I am having trouble with adding an item listener to my buttons on a GUI I have made. I have tried the code
searchButton.addItemListener(this);
clearFormButton.addItemListener(this);
and I get the following error:
jobFinderGui.java:6: jobFinderGui should be declared abstract; it does not define actionPerformed(java.awt.event.ActionEvent) in jobFinderGui
public class jobFinderGui extends CloseableFrame implements ActionListener
The following is my code listing:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
public class jobFinderGui extends CloseableFrame implements ActionListener
JLabel jobTitleLabel;
JTextArea jobTitleTextArea;
JScrollPane sp_jobTitleTextArea;
JLabel salaryLabel;
Choice salaryChoice;
JLabel phrasesLabel;
JTextArea phrasesTextArea;
JScrollPane sp_phrasesTextArea;
JButton searchButton;
JButton clearFormButton;
JLabel resultsLabel;
JTextArea resultsTextArea;
JScrollPane sp_resultsTextArea;
     private int totalJobs = 0;
public jobFinderGui()
jobFinderLayout customLayout = new jobFinderLayout();
getContentPane().setFont(new Font("Helvetica", Font.PLAIN, 12));
getContentPane().setLayout(customLayout);
jobTitleLabel = new JLabel("Enter the Title of the job(s) you are searching for:");
getContentPane().add(jobTitleLabel);
jobTitleTextArea = new JTextArea("");
sp_jobTitleTextArea = new JScrollPane(jobTitleTextArea);
getContentPane().add(sp_jobTitleTextArea);
salaryLabel = new JLabel("Choose desired salary:");
getContentPane().add(salaryLabel);
salaryChoice = new Choice();
salaryChoice.addItem("0 - 19999");
salaryChoice.addItem("20000 - 39999");
salaryChoice.addItem("40000 - 59999");
salaryChoice.addItem("60000 - 79999");
salaryChoice.addItem("80000 - 99999");
salaryChoice.addItem("100000+");
getContentPane().add(salaryChoice);
phrasesLabel = new JLabel("Enter key phrase(s):");
getContentPane().add(phrasesLabel);
phrasesTextArea = new JTextArea("");
sp_phrasesTextArea = new JScrollPane(phrasesTextArea);
getContentPane().add(sp_phrasesTextArea);
searchButton = new JButton("Search");
getContentPane().add(searchButton);
          searchButton.addActionListener(this);
clearFormButton = new JButton("Clear");
getContentPane().add(clearFormButton);
resultsLabel = new JLabel("Please find below the results from your search:");
getContentPane().add(resultsLabel);
resultsTextArea = new JTextArea("");
sp_resultsTextArea = new JScrollPane(resultsTextArea);
          resultsTextArea.setEditable(false);
getContentPane().add(sp_resultsTextArea);
setSize(getPreferredSize());
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
public static void main(String args[]) {
jobFinderGui window = new jobFinderGui();
window.setTitle("jobFinder");
window.pack();
window.show();
class jobFinderLayout implements LayoutManager {
public jobFinderLayout() {
public void addLayoutComponent(String name, Component comp) {
public void removeLayoutComponent(Component comp) {
public Dimension preferredLayoutSize(Container parent) {
Dimension dim = new Dimension(0, 0);
Insets insets = parent.getInsets();
dim.width = 725 + insets.left + insets.right;
dim.height = 406 + insets.top + insets.bottom;
return dim;
public Dimension minimumLayoutSize(Container parent) {
Dimension dim = new Dimension(0, 0);
return dim;
public void layoutContainer(Container parent) {
Insets insets = parent.getInsets();
Component c;
c = parent.getComponent(0);
if (c.isVisible()) {c.setBounds(insets.left+8,insets.top+8,312,24);}
c = parent.getComponent(1);
if (c.isVisible()) {c.setBounds(insets.left+336,insets.top+8,368,72);}
c = parent.getComponent(2);
if (c.isVisible()) {c.setBounds(insets.left+8,insets.top+96,288,24);}
c = parent.getComponent(3);
if (c.isVisible()) {c.setBounds(insets.left+336,insets.top+96,136,24);}
c = parent.getComponent(4);
if (c.isVisible()) {c.setBounds(insets.left+8,insets.top+136,288,24);}
c = parent.getComponent(5);
if (c.isVisible()) {c.setBounds(insets.left+336,insets.top+136,368,72);}
c = parent.getComponent(6);
if (c.isVisible()) {c.setBounds(insets.left+216,insets.top+224,96,24);}
c = parent.getComponent(7);
if (c.isVisible()) {c.setBounds(insets.left+336,insets.top+224,96,24);}
c = parent.getComponent(8);
if (c.isVisible()) {c.setBounds(insets.left+184,insets.top+264,336,24);}
c = parent.getComponent(9);
if (c.isVisible()) {c.setBounds(insets.left+24,insets.top+296,688,104);}
Any help in sorting out this would be greatly appreciated.

Answer 1

you are getting the error cause you are implementing the ActionListener
and you dont have the actioPerformed() {} method in your class I am not sure what you are trying to do cause I have not took the time to look over all your code but you might be wanting to implement itemListener and use the itemStateChanged(){} method
just a thought as i was passing by
