Thread: Just need some help with my program ... i really dont know how to get the total to print in my for loop :(((((((((((((((((

Write a program to calculate the telephone charges for four customers. The data for
each customer consists of
NAME, PREVIOUS METER READING, PRESENT METER READING
The difference between the two readings gives the number of units used by the
customer for the period under consideration. The amount due for each customer is
calculated by:
UNITS USED * RATE PER UNIT + RENTAL CHARGE
The rate per unit and rental charge is assumed to be the same for all customers and
must be input once only.
Your program must:
a. Input the rate and rental charge
b. Read the data for each customer and calculate the amount due
c. Print the information under suitable headings
d. Calculate and print the total amount due to the telephone company

I just need the totalX in my for loop to print the total but the total i want to print it is in the while loop



can someone help me plzzz would greatly be thankful for any help

Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

The graphic you posted is difficult to see. Read the above link and copy/paste your code between code or highlight tags as described there.

If the total is being calculated, but it's local in scope to a while loop, then declare the variable that holds the total outside the while loop where it will be available to other parts of the program.

Giving you more specific guidance will be easier after seeing the code.

this is my java code.. plz feel free to make any changes ...

Im new to this kind of programming so i will be thankful for any help i can get


package Project;

import java.io.*;
public class Question3 {
private static String amount;
public static String total;
String names=null;


/**
* @param args the command line arguments
* @throws java.lang.Exception
*/
public static void main(String[] args) throws Exception {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String names [];//This is the declaration
names = new String[5];//Create an array

//While loop
int x=0;
while(true){

System.out.println("Please enter client name");
names [x] = br.readLine();
//enter rate
System.out.println("Please enter rate");
float rate= Float.parseFloat(br.readLine());
System.out.println("Please enter rental");
//rental
float rental = Float.parseFloat(br.readLine());
//Prev meter reading
System.out.println("Please enter previous meter reading: ");
float prevMeter = Float.parseFloat(br.readLine());
//Present meter reading
System.out.println("Please enter present meter reading: ");
float presMeter= Float.parseFloat(br.readLine());
//Unit used
float unitUsed =prevMeter-presMeter;
//calculation of total amount
float totalX = rental+(unitUsed*rate);
System.out.println("$"+totalX+" is the amount due for "+names[x]);


//ask to enter another
String data;
System.out.println("Would like to enter another client ");
data = br.readLine();
if(data.equals("no")){
break;
}//close if statement
x++;


}//end while loop
//for loop
for(int k=0; k<2; k++){
System.out.println(totalX +" is the total amount for "+ names[x]);
}



}


}

--- Update ---

I just want it to print like this for example :

This is the amount for jack (amount of cash).
This is the amount for jane (amount of cash)
