Multiple Action Listeners

I need to make multiple action listeners for 4 radio buttons and a regular button. They all need to call different methods from another class

I currently have

Java Syntax (Toggle Plain Text) 
  1. Import javax.swing.*;
  2. import java.awt.*;
  3. import java.awt.event.*;
  4.  
  5. public class CardGameCH15 extends JFrame
  6. {
  7.  
  8.  
  9. 	public CardGameCH15()
  10. 	{
  11. 		super("Card Game");
  12. 		add(new CardTable());
  13.  
  14. 	}
  15.  
  16. 	public static void main(String[] args)
  17. 	{
  18. 		CardGameCH15 frame = new CardGameCH15();	
  19. 		frame.setSize(500,200);
  20. 		frame.setTitle("Card Game");
  21. 		frame.setLocationRelativeTo(null);
  22. 		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  23. 		frame.setVisible(true);
  24.  
  25. 	}
  26.  
  27. 	class CardTable extends JPanel implements ActionListener
  28. 	{
  29. 	  	String card;
  30. 		ImageIcon cardIcon;
  31. 		JButton dealButton = new JButton("Deal 5");
  32. 		CardDeck deck;
  33. 		JLabel card1 = new JLabel("");
  34. 		JLabel card2 = new JLabel("");
  35. 		JLabel card3 = new JLabel("");
  36. 		JLabel card4 = new JLabel("");
  37. 		JLabel card5 = new JLabel("");
  38. 	   JRadioButton jrb1 = new JRadioButton("1 Deck");	
  39. 	   JRadioButton jrb2 = new JRadioButton("2 Decks");
  40. 		JRadioButton jrb3 = new JRadioButton("3 Decks");
  41. 		JRadioButton jrb4 = new JRadioButton("4 Decks");	
  42.  
  43.  
  44.  
  45.  
  46.  
  47. 		public CardTable()
  48. 		{
  49. 				setLayout(new FlowLayout());
  50.  
  51. 			deck = new CardDeck(1);
  52. 			dealHand();
  53. 			add(card1);
  54. 			add(card2);
  55. 			add(card3);
  56. 			add(card4);
  57. 			add(card5);
  58. 			add(dealButton);
  59. 			add(jrb1);
  60. 			add(jrb2);
  61. 			add(jrb3);
  62. 			add(jrb4);	
  63.  
  64. }
  65. 				dealButton.addActionListener(new ActionListener(){
  66. 				public void actionPerformed(ActionEvent e) {
  67. 				dealHand();
  68. 				}
  69. 				});
THE ABOVE ACTION LISTENER IS NOT WORKING, IS THERE ANOTHER WAY OF WRITING MULTIPLE ACTION LISTENERS OR DID I MAKE A SYNTAX ERROR

Java Syntax (Toggle Plain Text) 
  1. 	private void dealHand()
  2. 		{
  3. 			String str;
  4.  
  5. 			if((str = deck.getCard()) != null)
  6. 				card1.setIcon(new ImageIcon("image/card/" + str));
  7. 			else
  8. 				return;
  9. 			if((str = deck.getCard()) != null)
  10. 				card2.setIcon(new ImageIcon("image/card/" + str));
  11. 			else
  12. 				return;
  13. 			if((str = deck.getCard()) != null)
  14. 				card3.setIcon(new ImageIcon("image/card/" + str));
  15. 			else
  16. 				return;
  17. 			if((str = deck.getCard()) != null)
  18. 				card4.setIcon(new ImageIcon("image/card/" + str));
  19. 			else
  20. 				return;
  21. 			if((str = deck.getCard()) != null)
  22. 				card5.setIcon(new ImageIcon("image/card/" + str));
  23. 			else
  24. 				return;
  25. 		}
  26. 	}
  27. }

I would appreciate any help...Thanks in advance

Put a quick print statement at the start of your dealHand method so you can see if it's the listener call that's failing or the dealHand method itself. I haven't checked all the brackets and semicolons, but the way you are defining the listener is the normal way to do it.

its not the deal hand method because when I just had a single action listener done something like

Java Syntax (Toggle Plain Text) 
  1. dealbutton.addActionListener(this);.....
  2. .....
  3. public void actionPerformed(ActionEvent e)
  4. 		{
  5. 			dealHand();
  6. 		}

everything worked fine but now that I need multiple action listeners for my radio buttons im havin issues

Well, looking at that brace on line 64, your code to add the listener is not in a method at all. So you've left out some other code in your post or that piece above won't even compile.

Getting closer!! now im getting this error

CardGameCH15.java:27: CardGameCH15.CardTable is not abstract and does not override abstract method actionPerformed(java.awt.event.ActionEvent) in java.awt.event.ActionListener
class CardTable extends JPanel implements ActionListener

That's because you moved the code into the anonymous listener. If you aren't going to define that method on your class then remove the "implements ActionListener" from your class declaration.
