Java End-of-file

  • synhack + 4 comments

    In fact, you can shorten it even further (at a potential loss of readability) by including the print statement within the for loop:

    for(int i = 1; scan.hasNext(); System.out.println(i + " " + scan.nextLine()), i++);

      Even shorter: 

      for(int i=1; scan.hasNext() ; System.out.println(i++ +" "+scan.nextLine()));

        That's pretty sweet! Thanks.

        That's not very readable code! A while loop is more appropriate.

      what does Scan.hasNext() exactly means??
      And while in the for loop we are not comparing Scan.hasNext() ??

      • JeanDuarte + 0 comments

        U shall read Scan.hasNext like this.... does "Scan" have next element ? If it has, it returns TRUE, so while something is TRUE, keep it going. That's why you don't need any comparing.

        sorry for being late,scan.hasNext() means after getting one input sacanner will wait for the next input .
