Dont know what I am doing wrong with my program help please!

When I did this program it compile fine, but when I run it I get this error:

java.util.NoSuc hElementExcepti on
at java.util.Scann er.throwFor(Sca nner.java:838)
at java.util.Scann er.next(Scanner .java:1461)
at java.util.Scann er.nextInt(Scan ner.java:2091)
at java.util.Scann er.nextInt(Scan ner.java:2050)
at Program4.main(P rogram4.java:30 )

I don't understand why because I put the input file in the directory of the program.
Here is the program:
import java.util.Scann er;
import java.io.*;

import java.text.Numbe rFormat;
public class Program4
{
public static void main(String [] args) throws IOException

{
File input = new File("spraying. txt");
Scanner scan = new Scanner(input);

int clientNumber,ty pe,acres;
double amountDue;
int number,total,co unter;

System.out.prin t("Client Number ");
clientNumber = scan.nextInt();

System.out.prin t("Type");
type = scan.nextInt();


total = acres = 0;

while(acres < 9999)
{
System.out.prin t("Acres");
acres = scan.nextInt();
total += type;
acres++;
}
if (acres > 0)
{
amountDue = calculateBill(t ype,acres);
NumberFormat fmt = NumberFormat.ge tCurrencyInstan ce();
fmt.format(amou ntDue);
//amountDue = (double) total/acres;
System.out.prin tln("The total billing is: "+acres+" numbers is "+amountDue );
}
else
System.out.prin tln("There was no input");
scan.close();
}
public static double calculateBill(i nt type,int acres)
{
int multiplier;
double grossBill;
if (type==1)
multiplier=1;
else if (type==2)
multiplier=3;
else if (type==3)
multiplier=4;
else if (type==4)
multiplier=6;
else
return -1;
grossBill = multiplier * acres;
if (acres > 1000)
grossBill -= 0.05*grossBill;
if (grossBill > 1500)
grossBill -= .1 * (grossBill-1500);
return grossBill;
}
}

Nevermind the first question, I figured out what was wrong, now Im getting a compiler error saying "cannot find symbol - class clientNumber" I was not getting this before.

Here is the new program:

import java.util.Scann er;
import java.io.*;
import java.text.Numbe rFormat;
public class Program4
{
public static void main(String [] args) throws IOException

{
File input = new File("spraying. txt");
Scanner infile = new Scanner(input);



int clientNumber,ty pe,acres;
double amountDue;
int number,total,co unter;


{

clientNumber = infile.nextInt( );
while(clientNum ber < 9999)
type = infile.nextInt( );
acres = infile.nextInt( );
infile.close();
total = acres = 0;
System.out.prin tln("Client Number/////////"+"Type/////////"+ "Acres////////"+ "Amount Due");




System.out.prin tln((clientNumb er)"///////"+ (type)"///////"+ (acres)"///////"+(amountDu e));



total += type;
acres++;
}
if (clientNumber== 0)
{

NumberFormat fmt = NumberFormat.ge tCurrencyInstan ce();
amountDue = calculateBill(t ype,acres);
fmt.format(amou ntDue);
//amountDue = (double) total/acres;
System.out.prin tln("The total billing is: "+acres+" numbers is "+amountDue );
}

//else
System.out.prin tln("There was no input");

}
public static double calculateBill(i nt type,int acres)
{
int multiplier;
double grossBill;
if (type==1)
multiplier=1;
else if (type==2)
multiplier=3;
else if (type==3)
multiplier=4;
else if (type==4)
multiplier=6;
else
return -1;
grossBill = multiplier * acres;
if (acres > 1000)
grossBill -= 0.05*grossBill;
if (grossBill > 1500)
grossBill -= .1 * (grossBill-1500);
return grossBill;
}
}

add a + after (clientNumber), otherwise it looks like a class cast.

Thank you , I fixed this now I am getting a different error for that line, could possible my while loop be in the wrong spot, I am trying to loop (clientNumber) (acres), and (type) untill it reads a 0

import java.util.Scann er;
import java.io.*;
import java.text.Numbe rFormat;
public class Program4
{
public static void main(String [] args) throws IOException

{
File input = new File("spraying. txt");
Scanner infile = new Scanner(input);



int clientNumber,ty pe,acres;
double amountDue;
int number,total,co unter;


{

clientNumber = infile.nextInt( );

while(clientNum ber < 9999)

type = infile.nextInt( );
acres = infile.nextInt( );
infile.close();
total = acres = 0;
System.out.prin tln("Client Number/////////"+"Type/////////"+ "Acres////////"+ "Amount Due");




System.out.prin tln((clientNumb er)+"///////"(type)+"///////"(acres)+"///////"+(amountDu e));



total += type;
acres++;
}
if (clientNumber== 0)
{

NumberFormat fmt = NumberFormat.ge tCurrencyInstan ce();
amountDue = calculateBill(t ype,acres);
fmt.format(amou ntDue);
//amountDue = (double) total/acres;
System.out.prin tln("The total billing is: "+acres+" numbers is "+amountDue );
}

//else
System.out.prin tln("There was no input");

}
public static double calculateBill(i nt type,int acres)
{
int multiplier;
double grossBill;
if (type==1)
multiplier=1;
else if (type==2)
multiplier=3;
else if (type==3)
multiplier=4;
else if (type==4)
multiplier=6;
else
return -1;
grossBill = multiplier * acres;
if (acres > 1000)
grossBill -= 0.05*grossBill;
if (grossBill > 1500)
grossBill -= .1 * (grossBill-1500);
return grossBill;
}
}

Not sure how your algorithm is working but probably:
if (clientNumber == 0) break;

Adding code tags will get you a slightly faster response to your questions.
