I am trying to read a txt file with java and put it in an array. I am getting an error on the new Scanner(file) that says unhandled exception type FileNotFoundException.

any help would be greatly appreciated.

package userInterface;
import java.util.*;
import java.io.*;

public class ChargeTest {
	
	public static void main(String[] args)
	{		
		
		final int SIZE = 5;
		int[] numbers = new int[SIZE];
		int index = 0;
		
		File file = new File("Values.txt");
		Scanner inputFile = new Scanner(file);
		
		while (inputFile.hasNext() && index< numbers.length)
		{
			numbers[index] = inputFile.nextInt();
			index++;
		}
		
		inputFile.close();

	}

}

Your compiler is saying that you do not take into account the possibility that your File may not exist. Try something like this (make sure to import java.io.*:

Scanner scan = null;
File f = null;
try{
	f = new File("path");
	scan = new Scanner(f);
}
catch(FileNotFoundException e){
	System.out.println("File not found");
	System.out.pritnln("Exiting");
	System.exit(0);
}

What will happen is if your File isn't found, then the program will exit.

I have the import.java.io.*; at the top of my code. Is there any reason why it won't find my file? I have it in the same folder my code is saved in. I am using IBM rational software architect.

Whoops- I forgot that the ; followed by the ) symbols would create an emoticon.

By the "path" I placed in your File constructor, I meant replace that with the actual file path (or if it is in the same folder, the name of the File).

I tried that now, and when I try to read it, the output is just the filename...
