Thread: Addition

A company provides 4 different services whose costs are as follows:
Service 1: $100
Service 2: $200
Service 3: $300
Service 4: $400
Write a Java application that reads the service(s) provided to a particular customer then calculates and display the total charge of all services provided. You should be able to use some technique we learned in class to determine when program should stop looping and then display the final results. Perhaps end the program when “0” is entered. Note: The GUI is not required.

Here is what I have so far:

import java.util.Scanner;
public class Service2 {
public static void main(String agrs []){
Scanner input = new Scanner(System.in);

int service1 = 100;
int service2 = 200;
int service3 = 300;
int service4 = 400;
System.out.println("Enter service number, (1-4), (the program exits if the input is 0): ");
int data = input.nextInt();

// keep reading data until the input is 0

int sum = 0;
while (data != 0){
sum +=data;

System.out.println("Enter service number, (1-4), (the program exits if the input is 0): ");
data = input.nextInt();

}
System.out.println("The sum is " + sum);

} // end main
} // end

I dont have any errors however, I dont the output that I'm looking for. I need to somehow multiply or add the services to get the output of: 1 + 3 = 300.

need to somehow multiply or add the services to get the output of: 1 + 3 = 300.

Can you explain your arithmetic?
What is the 1 and the 3 and the 300?
Normally 1 + 3 = 4?

Have you looked at using an array to hold the charges for each of the services?
The elements would be the charge amount, the index would be the service id number.

I'm sorry I'm so new at this. What should the if statement say????

In the top of the question it states the different services that are provided. Service 1 = 100....Service 4 = 400.

My current program reads 1 + 3 =4. I need it to say 1 + 3= 400

Again Im new the if statement should be in between the while statement?

Help me out Junky?? how should I write this.

Thanks your awesome!!!

Ummmm its still not working?

Again Im very new...... the if statement should be in ()?

I got Junky; a little different but you really really really help me a lot..
