Can anyone help me with this JList........?

Question

Well have a look at this simple code
I just want to get the item selected in the JList selected to be written in the JTextArea....It compiles ok but when it runs this is the error in the actually JText area......"[Ljava.lang.object,@2611a7]"
What ever that means...I think you'll see from this code........
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
     public class CoffeeMachine extends JFrame {
          private JLabel promptLabel;
          private JList drinkList;
          private JTextArea outputArea;
          private Container container;
          private JButton button1;
          private String drinkNames[] = {"Black Coffee", "White Coffee", "Extra Strong Coffee"};
     public CoffeeMachine()
          super( ":: Please Select a drink ::");
          Container container = getContentPane();
          container.setLayout( new FlowLayout());
          drinkList = new JList( drinkNames );
          promptLabel = new JLabel( "Select a drink from the drop menu (below) ");
          container.add(promptLabel);
          drinkList.setSelectionMode(
          ListSelectionModel. SINGLE_INTERVAL_SELECTION);
               container.add( new JScrollPane( drinkList));
          button1 = new JButton( "OK");
          button1.addActionListener(
     new ActionListener(){
     public void actionPerformed ( ActionEvent event)
     outputArea.setText("Water is boiling your " + drinkList.getSelectedValues() + "please wait");
     container.add( button1 );
     outputArea = new JTextArea (10,20);
     outputArea.setEditable (false);
     container.add(new JScrollPane(outputArea));
     setSize(275, 260 );
     show();
     public static void main( String args[])
     CoffeeMachine application = new CoffeeMachine();
     application.setDefaultCloseOperation(
          JFrame.EXIT_ON_CLOSE);

Sounds like a use for java.util.HashMap.
A HashMap stores key-value -pairs and gives you methods to get and set the value knowing the key. In this case you would have the name of coffee as a key and the object representing the type of the coffee in detail as a value.
Bit like this: import java.util.HashMap;
HashMap coffeeTypes = new HashMap();
CoffeeType blackCoffee = new CoffeeType(NO_MILK);
coffeeTypes.put("Black Coffee", blackCoffee);
CoffeeeType selectedCoffee = (CoffeeeType) coffeeTypes.get("Black Coffee"); Of course instead of literal strings in the example you would use the values you from the list for keys - and you need to define a class that represents a coffee type with the amounts of milk, coffee (different coffee blends..) and water.
