Programming asissitance

[jose]

I am a beginner and I am having trouble understanding java. I need to write a program that recieved inputs of numbers worked and out puts
pay:$.01 on day 1. Total Salary $.01
pay:$.02 on day 2. Total Salary $.03
pay:$.04 on day 3. Total Salary $.07
ECT. Can any one assist me in writting this program.

Sure, you can get help here. But I don't think there are a lot of people willing to write the programm for you.
So let's see what you got sofar and tell us what it is you don't understand.

/* In this project I will have 30 days of pay and total sallary doubleing

public class PenniesForPay
{
/**We will start by identifying the methods**/
public static void main (String[] args)
{
Scanner scannerObject = new Scanner(System.in);

/*Variables*/

int payPerDay;
int totalSalary;
int days;

payPerDay = .01 * .02;
days = 40;
totalSalary = payPerDay + totalSalary;

Systemprintln(pay: "$" + on day "days". + totalSalary);

[prometheuzz]

/*Variables*/
int payPerDay;
int totalSalary;
int days;

payPerDay = .01 * .02;
days = 40;                 
totalSalary = payPerDay + totalSalary; 

Systemprintln(pay: "$" + on day "days". + totalSalary);

Ok, payPerDay is an int and you can't use decimals there, only whole numbers. And why do you multiply values? Isn't it a fixed amount someone would get for a days work?

Wouldn't totalSalary be the number of days times payPerDay.

Also don't forget semicolons after every line!
And ininitiase your variables like this:

int payPerDay = 0;
int totalSalary = 0;
int days = 0;

After you did all that try printing it out like this:

System.out.println("Pay per day: "+payPerDay+", and worked: "+days+" number of days, so the total is: "+totalSalary);

It's alse a wise thing to read some Java tutorials:
http://java.sun.com/docs/books/tutorial/

Good luck.

Thanks I will try that and I will read the tutorials. I will do my best to learn it but it is some times hard to understand.

Everything is hard at the beginning. One step at a time.
Do post if you get stuck.

Good luck.

[jose]

I will, thanks

I can't come up with the pay per day and total salary. can any one help?
below is my program. Can any one assist me.

Hey Jose,

I see you've put a lot of effort in it up till now. But I think you're getting a bit of-track now. If I read through your first post, you said you needed the following output:
pay:$.01 on day 1. Total Salary $.01
pay:$.02 on day 2. Total Salary $.03
pay:$.04 on day 3. Total Salary $.07

But I see you do a lot more then necessary. The following code will do just that what you described:

import java.text.DecimalFormat;

public class penniesforpay078 {

    // main method
    public static void main (String[] args) {

        // variables
        int numOfDays = 30;
        double payPerDay = 0.01;
        double totalSalary = 0.0;

        for(int i = 1; i <= numOfDays; i++) {

            totalSalary = totalSalary + payPerDay;
            DecimalFormat df = new DecimalFormat("0.00");
            System.out.println("pay:$ "+payPerDay+" on day "+i+". Total Salary $"+df.format(totalSalary));
            payPerDay = payPerDay * 2;

        } // end for loop

    } // end main

} // end class penniesforpay078

Read it through carefully and try to understand what's happening. Good luck finishing your assignment.

thank you

[prometheuzz]

thank you

You're welcome.

I modified it a little and it still worked thank you for the help. I will be on here a lot and I will be reading the tutorials

Ok, well done Jose.
Happy programming!
