the other problem i'm having is this:
I've created a Gui and an actionListener class; when I press the add button, the values are stored in temp variables. That's it.
What i'm TRYING to implement is to link that ActionListener class with the subclass of the abstract class (as detailed above), send the information aquired in the actionlistener class to that subclass, and create an object with those values and store them in an ArrayList.
It's a bit complicated, so that's why i need a little help

here's the ActionListener class:
import java.awt.*; import javax.swing.*; import java.util.ArrayList; import java.awt.event.ActionEvent; import java.awt.event.*; public class ActionListen implements ActionListener { private GuiInfo gui; String getName, getDisplay, getWork, getHome, getMobile; String getName2, getDisplay2, getEmail2; String getName3, getDisplay3, getAddress3; ArrayList obj; public ActionListen(GuiInfo gui) { this.gui = gui; } public void actionPerformed(ActionEvent event) { if (event.getSource() == "addButton") { getName = gui.getNameInfo(); getDisplay = gui.getDisplayInfo(); getWork = gui.getWorkInfo(); getHome = gui.getHomeInfo(); getMobile = gui.getMobileInfo(); phone.phone(getName, getDisplay, getWork, getHome, getMobile); } gui.nameField.setText(""); gui.displayField.setText(""); gui.workField.setText(""); gui.homeField.setText(""); gui.mobileField.setText(""); if (event.getSource() == "addButton2") { getName2 = gui.getNameInfo2(); getDisplay2 = gui.getDisplayInfo2(); getEmail2 = gui.getEmailInfo2(); } gui.nameField2.setText(""); gui.displayField2.setText(""); gui.emailField2.setText(""); if (event.getSource() == "addButton3") { getName3 = gui.getNameInfo3(); getDisplay3 = gui.getDisplayInfo3(); getAddress3 = gui.getAddressInfo3(); } gui.nameField3.setText(""); gui.displayField3.setText(""); gui.addressField3.setText(""); }

I'm getting an "invalid method delaration: return type required" error message in the constructor when trying to compile a sub-class of an abstract class.
Here is the code for the abstract class:

abstract class Item { public int name; public int displayName; }

and here is the code for its subclass:

public class Phone extends Item { private String work; private String home; private String mobile; public phone (String name, String display, String work, String home, String mobile) { super(name, display); this.work = work; this.home = home; this.mobile = mobile; } }

yea i changed that already, got any suggestions on how i can make this work?

how would I access the text from a textfield in a gui class at the click on a button and send that info into my actionlistener class?
The current error i get is "salary has private access in java.awt.Component"
This is the actionlistener class (not complete yet)
import java.awt.*; import javax.swing.*; import javax.swing.border.*; import java.awt.event.ActionEvent; import java.awt.event.*; public class ActionListen implements ActionListener { private GuiInfo gui; String getName, getDisplay, getWork, getHome; String getName2, getDisplay2, getEmail2; String getName3, getDisplay3, getAddress3; public ActionListen(GuiInfo gui) { this.gui = gui; } public void actionPerformed(ActionEvent event) { if (event.getSource() == "addButton") { JOptionPane.showMessageDialog(null, "Item Added to Database"); String getName = (JTextField) GuiInfo.name.getText(); String getDisplay = GuiInfo.display.getText(); String getWork = GuiInfo.display.getText(); String getHome = GuiInfo.display.getText(); String getMobile = GuiInfo.display.getText(); } else if (event.getSource() == "addButton2") { String getName2 = GuiInfo.name2.getText(); String getDisplay2 = GuiInfo.display2.getText(); String getEmail2 = GuiInfo.email2.getText(); } else if (event.getSource() == "addButton3") { String getName3 = GuiInfo.name3.getText(); String getDisplay3 = GuiInfo.display3.getText(); String getAddress3 = GuiInfo.address3.getText(); } }

This is PART of the Gui class, and the tabbed pane where the JTextField reside. (only the parts that count)

import java.awt.*; import javax.swing.*; import javax.swing.border.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; class GuiInfo extends JFrame { ActionListen action; public GuiInfo() { action = new ActionListen(this); } public Component makeAddPanel() { ... ... JButton addButton = new JButton("Add Item"); JButton addButton2 = new JButton("Add Item"); JButton addButton3 = new JButton("Add Item"); addButton.addActionListener(action); addButton2.addActionListener(action); addButton3.addActionListener(action);

This is what I want:
when i click on one of the radio buttons (in the west panel), i want the center panel to display one of 3 cards. problem is, i can't seem to pull it off!
here's the code for that particular tab and the action listener method for it:
protected Component makeAddPanel() { JPanel addPanel = new JPanel(true); addPanel.setLayout (new BorderLayout ()); JPanel buttonPanel = new JPanel(); buttonPanel.setLayout (new BoxLayout(buttonPanel, BoxLayout.Y_AXIS)); JPanel textPanel = new JPanel(); textPanel.setLayout (new BoxLayout(textPanel, BoxLayout.Y_AXIS)); JPanel cards = new JPanel(); cards.setLayout(new CardLayout()); JPanel p1 = new JPanel(); p1.add(new JButton("Button 1")); p1.add(new JButton("Button 2")); p1.add(new JButton("Button 3")); JPanel p2 = new JPanel(); p2.add(new JTextField("TextField", 20)); JPanel p3 = new JPanel(); p3.add(new JTextField("TextField", 20)); cards.add(p1, PHONEPANEL); cards.add(p2, EMAILPANEL); cards.add(p3, POSTALPANEL); addPanel.add(cards, BorderLayout.CENTER); TextField textName = new TextField(); JLabel addLabel = new JLabel("Add an Item to the Database"); ButtonGroup radioButtons = new ButtonGroup(); JRadioButton phoneButton = new JRadioButton("Phone"); JRadioButton emailButton = new JRadioButton("E-Mail"); JRadioButton postalButton = new JRadioButton("Postal"); radioButtons.add(phoneButton); radioButtons.add(emailButton); radioButtons.add(postalButton); textPanel.add(textName); buttonPanel.add(phoneButton); buttonPanel.add(emailButton); buttonPanel.add(postalButton); addPanel.add(buttonPanel, BorderLayout.WEST); addPanel.add(addLabel, BorderLayout.NORTH); addLabel.setHorizontalAlignment(JLabel.CENTER); return addPanel; } public void itemStateChanged(ItemEvent evt) { CardLayout cl = (CardLayout)(cards.getLayout()); cl.show(cards, (String)evt.getItem()); }
thanks in advance!

ahhhh it's cool, i found the problem. Thanks for your help, mate!

i think i get you, this is what i changed it to:
class TestInheritence { public static void main(String[] args) { DevEmployee aDev; DevEmployee mike = new DevEmployee("Michael Dojo", 454443, "10/08/84", "Java, HTML, JavaScript", 45000); DevEmployee alex = new DevEmployee("Alex Trewen", 545999, "30/01/80", "Java, JavaScript, C+, C++, C#", 62000); DevEmployee john = new DevEmployee("John Andrews", 545955, "11/5/84", "Java, HTML", 12000); ArrayList a1 = new ArrayList(); a1.add(mike); a1.add(alex); a1.add(john); printAll(a1); } public double reduceWage(DevEmployee d, double amount) { return d.salary = d.salary - 5000; } public void printAll(ArrayList a) { DevEmployee aDev; for(int i=0; i < a.size(); i++) { System.out.println(i + 1 + "-----"); aDev = (DevEmployee) a.get(i); aDev.printInfo(); } } }
i get an error message saying:
C:\Text1.java:80: non-static method printAll(java.util.ArrayList) cannot be referenced from a static context printAll(a1); ^ 1 error

i didnt print the whole code, but here it is anyways:
import java.util.*; class DevEmployee extends Employee { String language; public DevEmployee(String n, double i, String d, String l, double s) { super(n, i, d, s); language = l; } public void printInfo() { System.out.println("Development Employee"); super.printInfo(); System.out.println("Language: " + language); System.out.println(); System.out.println(); } public boolean isEligible() { if(salary >= 50000) return true; else return false; } public void printAll(ArrayList a) { DevEmployee aDev; for(int i=0; i < a.size(); i++) { System.out.println(i + 1 + "-"); aDev = (DevEmployee) a.get(i); aDev.printInfo(); } } } class TestInheritence { public static void main(String[] args) { DevEmployee aDev; DevEmployee mike = new DevEmployee("Michael Dojo", 454443, "10/08/84", "Java, HTML, JavaScript", 45000); DevEmployee alex = new DevEmployee("Alex Trewen", 545999, "30/01/80", "Java, JavaScript, C+, C++, C#", 62000); DevEmployee john = new DevEmployee("John Andrews", 545955, "11/5/84", "Java, HTML", 12000); ArrayList a1 = new ArrayList(); a1.add(mike); a1.add(alex); a1.add(john); printAll(a1); } public double reduceWage(DevEmployee d, double amount) { return d.salary = d.salary - 5000; } }
and i still get the same error as above. Thanks in advance.

I want to pass an ArrayList into a method and print all the info in the arraylist. here's my code so far:
public void printAll(ArrayList a1) { DevEmployee aDev; for(int i=0; i < a1.size(); i++) { System.out.println(i + 1 + "-----"); aDev = (DevEmployee) a1.get(i); aDev.printInfo(); } } } class TestInheritence { public static void main(String[] args) { DevEmployee aDev; DevEmployee mike = new DevEmployee("Michael Dojo", 454443, "10/08/84", "Java, HTML, JavaScript", 45000); DevEmployee alex = new DevEmployee("Alex Trewen", 545999, "30/01/80", "Java, JavaScript, C+, C++, C#", 62000); ArrayList a1 = new ArrayList(); a1.add(mike); a1.add(alex); printAll(a1); }

i receive the following error:
C:\Text1.java:88: cannot resolve symbol symbol : method printAll (java.util.ArrayList) location: class TestInheritence printAll(a1); ^ 1 error
thanks in advance, peoples
