    static void DoPrint()
    Scanner boom = new Scanner(;

    • can you please edit it, that will print the sentence reversed without ruining the letters…

      example: I am cool
      reversed: cool am i

    • I managed to do this with a String array. I was wondering how to do it without using an array and then stumbled across this algorithm. Much simpler than I’d presumed. Thanks a lot.

      I have the site bookmarked.

      • It requires -1 because all strings end with a ‘\0’ character… while doing the reverse the null is not needed.. so -1 is used else the string will end up reversed one short.
