Examples of java.util.Scanner.nextLong()

java.util.Scanner.nextLong()
Scans the next token of the input as a long.
An invocation of this method of the form nextLong() behaves in exactly the same way as the invocation nextLong(radix), where radix is the default radix of this scanner. @return the long scanned from the input @throws InputMismatchException if the next token does not match the Integer regular expression, or is out of range @throws NoSuchElementException if input is exhausted @throws IllegalStateException if this scanner is closed

      myFile = new Scanner(new FileInputStream(f));
      int i = 0; //this will be our local array index
      System.out.println("\nCreating a temporary array from file " + f.getName() + " with " + n + " records.");
      while (myFile.hasNextLine()) { //to check for EOF
        //fill up our array 
        a[i] = new Warship(myFile.nextLong(), myFile.next(), myFile.nextInt(), 
                myFile.next(), myFile.nextDouble(), myFile.nextInt());
        i++; //increment the index
      }
    } catch (FileNotFoundException e) {
      System.out.println("There was an error creating the Scanner object from file " + f.getName());
