I have been working on this code and i am struggling...

this is what i have soo far. any input or tips would be greatly appreciated.

import java.util.*;
import java.io.*;


public class Lab14 {

public static void main(String[] args) throws FileNotFoundException {
// TODO Auto-generated method stub


File file = new File("inventory.txt");


Scanner reader = new Scanner(file);
double value = 0.0;
try{
while(reader.hasNext()){
value = reader.nextDouble();

}
}catch(InputMismatchException tim){
System.out.println("InputMismatch!!!!");
}

}
}

So far, your code is reading in the data from the file.
Try adding some output lines to check what it's doing.

Follow the next step, getting the total value.

(BTW What's in the data file?)
