Thanks for the help guys all of your suggestions have worked perfectly.
I got the file to read in correctly. I noticed though that I can only
read in a file if it's one line of text without any Enters. I'm using
the BufferedReader.readLine() command. I've tried to find another
method in the BufferedReader to do that but .read() only returns an
Int.

My text file looks like this
--------------
test.txt
--------
This is a test from line 1 in my file
This is a test from line 2 in my file
This is a test from line 3 in my file
--------------------------

When I read it in it only returns the first line. Is there anyway I
could get it to read in all three lines and return it all as a big
string?

public static String readInFile(String fileName) //Should have file
name as parameter
    {
        String returnText= "none";
        try
        {
            FileReader file = new FileReader(fileName);
            BufferedReader br = new BufferedReader(file);
            returnText= br.readLine();
        }catch(Exception x){ System.out.println("Invalid File"); }

        return returnText;
         }

Thanks again for your help.

Reading a whole file into a string is dangerous, what if the whole file
is 2GB long?

I always just loop through reading each line and appending to a
StringBuffer until readLine is null. Something like this:

while ((line = in.readLine())!= null){
//process stuff
}
