		double Income, Tax, TaxTotal, Bills, OfficeSpace, LeftOver, Bill;
		int NBill, i, a, b;
		
		Bills = 0.;
		i = 1;
		
		System.out.println("Imput this month's income:");
		
		Income = Scan.nextDouble();
		
		System.out.println("Your current balence is $" + Income );
		System.out.println("How much of your income will you save for tax? (percentage, no percentage sign, whole num.)");
		
		Tax = Scan.nextDouble();
		
		System.out.println("$" + Income * (Tax / 100) + " goes to the Unchel Sam.");
		
		TaxTotal = Income * (Tax / 100);
		Income = Income - TaxTotal;
		
		System.out.println("Your new current balence is $" + Income );
		System.out.println("How many bills do you have?");
		
		NBill = Scan.nextInt();
		
		double[] Bnum = new double[NBill];
		Bnum[0] = 0;
		
		do{
			System.out.println("how much is value of bill " + i);
			Bnum[i] = Scan.nextDouble();
			i++;
			
		}while(i <= NBill);



		\\ this is deleted part


		System.out.println("Your new current value of used money is $" + Bnum);
		

		
	}
}

OK. What you want to achieve? And what error's you are getting?

I suspect you are getting array index out of bound exception.

System.out.println("Your new current value of used money is $" + Bnum);

What you want to print here?

Please post error messages too. And please wrap the code in code block.

the error is Exception in thread "main" java.lang.Array IndexOutOfBound sException: 2
at Income.main(Mon ey.java:37) the 2 is for how many bills you say you have so if i say i have 5 bill then the 2 will change to a 5

i am trying to make it so i can put in my monthly income and see how much money i have left over so say i made $200 this month (i am not poor) i would save 20% for tax then i say how many bills i have and the i add it up.

i am new at this i am only half way through the java book i am reading so if you have any recommendations i would happily take them.


also i see your picture is the eclipse symbol if you know any tricks for the program it would be much appreciated

sorry there is a bunch of stuff not used i am a very unorganized person and i half been trying to fix this error for 3 days strait last night was the only night i got some sleep

thank you for taking your time to help me

Indexes start at index 0.
Change it to
while(i < NBill);
removing the equal sign.
Couldn't you tell you were trying to input one too many bills?

i have not slept in 3 days how should i know and plus i changed it and ran it and it said (this is what the entire program said )
"Imput this month's income:
200
Your current balence is $200.0
How much of your income will you save for tax? (percentage, no percentage sign, whole num.)
20
$40.0 goes to the Unchel Sam.
Your new current balence is $160.0
How many bills do you have?
2
how much is value of bill 1
2
Your new current value of used money is $[D@1fb8ee3
"


compile it and run you will see what i mean

[Dheeraj Joshi]

System.out.println("Your new current value of used money is $" + Bnum);

It Should print the value in ith index.

So change it to

System.out.println("Your new current value of used money is $" + Bnum[index]);

i tried that and it gave me an error the error is
Exception in thread "main" java.lang.Error : Unresolved compilation problem:
index cannot be resolved

at Money.main(Mone y.java:42)




thanks for the help i am so frustrated i have been dreaming about ways to fix the program

[Dheeraj Joshi]

System.out.println("Your new current value of used money is $" + Bnum[index]);

Should not be this inside the while loop?

it is not my entire script is

import java.util.Scanner;

public class Money {
	public static void main(String[] args){
		
		Scanner Scan = new Scanner(System.in);
		double Income, Tax, TaxTotal, Bills, OfficeSpace, LeftOver, Bill;
		int NBill, i, a, b;
		
		Bills = 0.;
		i = 1;
		
		System.out.println("Imput this month's income:");
		
		Income = Scan.nextDouble();
		
		System.out.println("Your current balence is $" + Income );
		System.out.println("How much of your income will you save for tax? (percentage, no percentage sign, whole num.)");
		
		Tax = Scan.nextDouble();
		
		System.out.println("$" + Income * (Tax / 100) + " goes to the Unchel Sam.");
		
		TaxTotal = Income * (Tax / 100);
		Income = Income - TaxTotal;
		
		System.out.println("Your new current balence is $" + Income );
		System.out.println("How many bills do you have?");
		
		NBill = Scan.nextInt();
		
		double[] Bnum = new double[NBill];
		Bnum[0] = 0;
		
		do{
			System.out.println("how much is value of bill " + i);
			Bnum[i] = Scan.nextDouble();
			i++;
			
		}while(i < NBill);
		
		System.out.println("Your new current value of used money is $" + Bnum[index]);
		

		
	}
}

and it still gives me an error

thanks for the help

[Dheeraj Joshi]

index is undefined in your program. Move your print statement inside the while loop. In my last post i gave you the example. Not exact code.

System.out.println("Your new current value of used money is $" + Bnum[i]);

Note: You need to print it before incrementing i.
