Linking two classes

Posted: Nov 28, 2002 12:40 PM

I have two classes....Interface and Coffee. The InterFace is basically an options screen where the user chooses a coffee they want from a ComboBox....once the choice is made they click a JButton and the value is stored in the object String coffeeType.
The second class is where the coffee styles and amount are set.

I want to know how I can take the value in coffeeType into the other class Coffee and put it into its' appropriate instance so I can then deduct the amounts from a container class?


//Import the relevent classes
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

//define the class and set the properties for the Interface
public class InterFace extends JFrame implements ActionListener{
	
	private JComboBox coffeeStyle;
	private String names[] = {"Extra Strong", "Black Coffee", "White Coffee"};
	private JLabel label;
	private JButton selectButton;
	private JTextArea textArea;
	
public InterFace () //set up GUI
{
	super( "Coffee Machine" );
	
	Container container = getContentPane();  
	container.setLayout(new FlowLayout());   

	coffeeStyle = new JComboBox (names);     
	coffeeStyle.setMaximumRowCount( 3 );
	
	textArea = new JTextArea ( 5, 15 );
	container.add ( textArea );
		
	label = new JLabel( "Choose a Drink" );
	container.add( label );
	
	container.add( coffeeStyle);
	
	selectButton = new JButton( "Get Drink?" );
	container.add(selectButton);
	selectButton.addActionListener(this);	

	setSize( 400, 200);
	setVisible( true );
}

public void actionPerformed(ActionEvent e) {	
	Object anObject = e.getSource();	
	if (anObject == selectButton) {		
	String coffeeType = 		    	
	(String)coffeeStyle.getSelectedItem();		
	textArea.setText ("Getting your " + coffeeType);

}
}

public static void main( String args[])
{
	InterFace application = new InterFace();

	application.setDefaultCloseOperation(
	JFrame.EXIT_ON_CLOSE );
	
}
}

public class Coffee{          

	int coffee;
	int milk;
	int water;
	Coffee(int coffeeRequired, int milkRequired, int waterRequired)
{
	coffee=coffeeRequired;
	milk=milkRequired;
	water=waterRequired;
}
}

public defineCoffeeAmount 
{
	//amount of coffee, milk and water required for this instance of Coffee
	Coffee darkCoffee = new Coffee(30,0,100);  
	Coffee whiteCoffee = new Coffee(20,40,100);  
	Coffee extraStrongCoffee = new Coffee(40,20,100);
