Java finds one file but not another

import java.io.*; //Importing to read from file.import java.util.Scanner; //Importing Scanner class.import java.text.DecimalFormat; //Importing DecimalFormat class.public class StockAssessment    {public static void main(String[] args) throws IOException    {        System.out.println("");        // Setting up DecimalFormat.        DecimalFormat money = new DecimalFormat("$###.##");        // Setting up the scanner.        Scanner keyboard = new Scanner(System.in);         /*          Prompting for the file name and initalizing         it to fileName.          */           System.out.print("Name of the file?

Basically, I've got two text files in the same folder that my source code is in, and when i run the program, it will only find one, and throw the following exceptions at me, that i have no idea what they mean, or how to fix them, any help would be awesome

 

-------------------------------------------

Name of the file? StockData.txt

Exception in thread "main" java.util.InputMismatchException

        at java.util.Scanner.throwFor(Scanner.java:909)

        at java.util.Scanner.next(Scanner.java:1530)

        at java.util.Scanner.nextInt(Scanner.java:2160)

        at java.util.Scanner.nextInt(Scanner.java:2119)

        at StockAssessment.main(StockAssessment.java:46)

Press any key to continue . . .

It's finding the file fine. The problem is that you're calling nextInt on the scanner and the next thing in the file isn't an int.

 

Also please use code tags.

@fizzlesticks I need to read through a file sequentially though, and this is what the lines im trying to read look like,

DELL: Dell Inc

125 25.567 0.025 28.735 0.025

so shouldn't the next thing after the nextLine be nextInt?

Pasting what you have in that post into a file works fine for me, try remaking the file and pasting that in. It's possible your file got corrupt or has some nonprintable character in it that's screwing things up.

@fizzlesticks I've found out that you can't do what i'm trying to do, but now I have to take all of the data in as a string, but do you know if parseInt and parseDouble can get their data from specific lines of a string?

You can use the string.split method to get an array of all the strings then call parseInt on an element of the array.

@fizzlesticks It's an assignment for school, and we haven't covered arrays yet, do you know of any other way of doing this?

The first way you were doing it should work fine as long as the file is formatted correctly.

[LurzKesh1138]

@fizzlesticks The file is formatted that way because that's how it was given, so I can't change that aspect of it

Can you post the full file? The way it's formatted is good there's just a problem with it somewhere.

All of the numbers are doubles, so that inputFile.nextInt needs to be changed to nextDouble.

Also after reading all the numbers in a line you need to eat the newline character at the end, so at the end of the loop check if there is more input and if there is, do another inputFile.next() to move to the next line.

@fizzlesticks But that's my problem, I can't read all the numbers in the line due to the exceptions getting thrown, so im kindve stuck in a rut

You won't get errors if you make those changes.
