Industry news: What is the meaning of life?

  1. What is the meaning of life? (1 messages)

    Posted now on several websites, I am looking still for one Java expert to figure out the answer without running the code:

    public class MeaningOfLife {
      public static
    String findOutWhatLifeIsAllAbout() {
        int meaning = 0;
        for (int i = 0; i < 10; i++) {
          for (int j = 0; j < 20; j++) {
            for (int k = 0; k < 300; k++) {
              for
    (int m = 0; m < 7000; m++) {
                meaning += Math.random() + 1;
              }
            }
          }
        }

        return String.valueOf(meaning).replaceAll("0*$", "");
      }
      public static void main(String[] args) {
        System.out.println(findOutWhatLifeIsAllAbout());
      }
    }

     

    Think about what the output should be before you run it. Then try it out, preferably with the -server switch. On my machine it takes 15 seconds to find the meaning of life with -server and 25 seconds with -client. Patience is apparently a virtue.

    The question is: Why is it giving this result? And why does it even compile?
