- Trouble with while loop and storing data
- String fileName = "Data.txt";
- int [] fill = new int [6];
- try{
- Scanner fileScan = new Scanner(new File(fileName));
- int i = 0;
- while (fileScan.hasNextInt()){
- Scanner line = new Scanner(fileScan.nextLine());
- i++;
- line.next();
- fill[i] = line.nextInt();
- System.out.println(fileScan.nextInt());
- }
- }catch (FileNotFoundException e){
- System.out.println("File not found. Check file name and location.");
- System.exit(1);
