    Default 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

    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.

    //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]);
    }



    }


    }

    I just want it to print like this for example :

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