this is most of the code that i am useing to get the numbers from the file.
As you can see, i am already useing strings, but it is still reading the
full line. I would like it to read one number at a time.

FileReader theFile;
BufferedReader fileIn;
String oneLine;
int [] unsort = new int [10];
int n = 3;
int r = 1;
try{
theFile = new FileReader( fileName);
fileIn = new BufferedReader ( theFile );
while ( (oneLine = fileIn.readLine()) !=null){
unsort[r] = Integer.parseInt(oneLine);

}
System.out.println( unsort[1]);
}
catch(Exception e){
{ System.out.println (e); }
}
