Reading a file of integers (The hard way)

• public static int[] readNumbersFromFile

• • • • • • • • • ( String fileName, int n) throws IOException{
  • int[] arr = new int[n];
  • FileInputStream fileIn= new FileInputStream(fileName);
  • int currByte;
  • int currInt; int base = 8;
  • for(int i = 1; i < n; i++){
  • • for (int j = 3; j >= 0; j--)
    • currInt = s |
    • • ( unsignedByteToInt(fileIn.read()) << base*j );
    • }
  • fileIn.close();
  • }
