no problem

The variable should be declared like this

double totalcharge = 0;

Then inside the while loop, you can add it above the message format or under the if statement. This will add all the total.

totalcharge += total;

Also leave the message format in the while loop alone. Just keep it like this.

message = String.format("%s $%.02f",name,total);

Now above the JOptionPane this is the format for the Total Charge to show.

message = message + String.format("Total Charge $%.02f",totalcharge);

You just add another double variable. You can call it what ever you want. I called mine totalcharge. Then u add that variable inside the while loop to add all 3 totals. Then above the JOptionPane, you have to add another message format.

Yea, u just add the if statement above the message format.

import java.util.Scanner;
import javax.swing.JOptionPane;

public class bored
{
public static void main( String args[])
{

Scanner input = new Scanner( System.in );

double kilowatts=0;
String name;
String message needs to have this since JOptionPane wont see it initialized.
String message = "";
double charge=0;

int counter=1;

while( counter <= 3)
{


System.out.println( "Enter name: ");
name = input.nextLine();

System.out.println( "Enter kilowatts: ");
kilowatts = input.nextInt();

charge = kilowatts * .056;

The \n has to be inside the quotations.
message += String.format( "%s $%.2f \n", name, charge);

counter++;
input.nextLine();


}

JOptionPane.showMessageDialog (null, message );

}

}

Alright just got off work. Now if u still need the 2nd part of the homework about showing each name in one list.

Here is the part in the first one where u have a format.
message = String.format("%s $%.02f,name,total);

In the 2nd part all you do is add a + sign in front of the equal sign. And \n which is adding a new line for each name.
message += String.format("%s $%.02f\n,name,total);

Now the take the JOptionPane.showMessageDialog(null,message);, and move it outside the while loop. And thats the 2nd one.

If u rather have me email u on your gmail account instead of this site, I can as well.
