no problem

Ok great! thanks a lot man you were big help. Thanks for helping me out, im starting to get it a lot better now. I will see you in class tomorrow.

Again thanks

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);

ok i have my variable declared. Adding it to the message format, would it look like this?

message += String.format( "%s $%.2f\n", name, charge, totalcharge);

I am also not understanding where to add it inside the loop to add all 3 totals

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.

alright cool and how would part four work out?

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

Thanks a lot, it is working now. I know for part 3 you have to add an if statement inside the while loop. I am not sure exactly how to do that though.
I really appreciate your help

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 );

}

}

Ok i tried that but it is now giving me an error. Here is what my code looks like for part 2.

public class Electric2
{
public static void main( String args[])
{

Scanner input = new Scanner( System.in );

double kilowatts=0;
String name;
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;


message += String.format( "%s $%.2f", \n, name, charge);


counter++;


input.nextLine();


}

JOptionPane.showMessageDialog (null, message );

}

}
