How to store 5 numbers from a file into 5 seperate variables?

[kewlgeye]

Ok, I have 5 numbers in a file. Example: 5 8 7 2 1

they are stored in the file just like that with no commas and I need to read that file and store each number into a variable so I can compare each number seperately to another number.

I tried reading the post earlier from someone else but I don't think that this is the same kind of problem.

I could store a seperate file for each number and compare that way, but I am trying to be more efficient and save space. Could someone please tell me how to do this.

Thank you.

Do it with Scanner class....

have some experiments on nextInt() method.....

Ok, I did a little research on this and I found this code. I modified it a little to work for me, but I know it is not correct, I think that I am closer though, could you please help me understand what I am doing wrong, or need to do next?? thank you

Code:

import java.util.Scanner;   
import java.io.*;   
  
\\this section will be in an event created by a calculate button
 
        Scanner scanner = new Scanner(new File("test.txt"));   
           
        while (scanner.hasNext())   
            int a = (scanner.next());
            int b = (scanner.next());
            int c = (scanner.next());
            int d = (scanner.next());
            int e = (scanner.next());

Is this correct?

I need 5 variables that will store the 5 numbers on the same line in text file so each variable will be available for use later in the code.

Put it on a method instead... and invoke it when some event fired....

Don't forget to use close() method after that process....

Code:

while (scanner.hasNext())   
            int a = (scanner.next());
            int b = (scanner.next());
            int c = (scanner.next());
            int d = (scanner.next());
            int e = (scanner.next());

be careful when to use braces and when not to use it....

that code would only store the data from the file to variable a.

And about that implementation, i think you should initialize those variables on member's field....(global variable)

So that, you can just implement directly setters/getters method...

Thank you for your help sukatoa

I used the scanner class and nextInt() method like you said, and it almost looked similar to the code I posted earlier but I didn't use the has next, and put nextInt() instead of just next when adding to the variables of the type int.

If I had my code in front, I would have posted it for all to benefit if they are as novice as myself.

Thanks again.
