I have an applet that I am suppose to write for a java class. However, I am
stuck on one function of the applet. I need to keep a running total of
charges and display them in the status bar. I would appreciate any help
anyone can give. The applet works great as it is currently written, but the
totals do not reflect correctly. Please help.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class A6_8R extends JApplet implements ActionListener {
JLabel promptLabel;
JTextField inputField;
public void init()
{
Container container = getContentPane();
container.setLayout( new FlowLayout() );
promptLabel = new JLabel( "Enter number of hours: ");
inputField = new JTextField( 5 );
inputField.addActionListener( this );
container.add(promptLabel);
container.add(inputField);
}
public void actionPerformed( ActionEvent actionEvent)
{
double currentCharge = 0.00;
double hours = Double.parseDouble(actionEvent.getActionCommand() );
currentCharge = calculateCharges( hours );
showStatus( "Current charge: " + currentCharge + "; " + "Total Receipts: " +
calculateTotal( currentCharge ));
}
public double calculateCharges( double hours )
{
final double minimumCharge = 2.00;
final double maximumCharge = 10.00;
double finalCharge = 0.00;
if ( hours <= 3.0 )
{
finalCharge = minimumCharge;
}
else if ( hours > 3.0 && hours < 24.0)
{
finalCharge = minimumCharge + (0.50 * (hours - 3.0));
}
else if ( hours == 24.0)
{
finalCharge = maximumCharge;
}
return finalCharge;
}
public double calculateTotal ( double currentCharge )
{
double totalReceipts = 0.00;
totalReceipts += currentCharge;
return totalReceipts;
}
}
