Lotto - google caliper Benchmark

[Xyz1]

Werte Leute, Hallo,

inspiriert durch dieses Thema:
http://www.java-forum.org/thema/zufallszahlen-ohne-wiederholung.173956/
das es hier schon mal gab (Lotto),
hab ich einfach mal vier Methoden aufgeschrieben, um das Problem zu lösen:

Mein Problem ist jetzt, ich verwende google caliper 0.5 rc1 und egal, was ich mache, ich bekomme immer:

run:

b6aus49() = [5, 16, 21, 24, 35, 37]
c6aus49() = [10, 11, 12, 17, 26, 29]
d6aus49() = [2, 18, 20, 25, 39, 45]

Ich hab auch kein How-To, Tutorial o. Ä. gefunden (außer ein YT-Video, das aber veraltet ist?). Ich hab auch caliper 1.0 usw. ausprobiert, aber es sollte schon unter WINDOW lauffähig sein.

Könnt ihr mir bitte behilflich sein?

Besten Dank

Ich habe es jetzt ausgetestet mit 0.5-rc1 und dabei ein paar Kleinigkeiten geändert (da Benchmarktests immer Rückgabewerte haben sollten!):

    public List<Integer> timeA6aus49(int reps) {
      List<Integer> dummy = null;
      for (int i = 0; i < reps; i++) {
        dummy = a6aus49();
      }
      return dummy;
    }
   
    public List<Integer> timeB6aus49(int reps) {
      List<Integer> dummy = null;
      for (int i = 0; i < reps; i++) {
        dummy = b6aus49();
      }
      return dummy;
    }
   
    public List<Integer> timeC6aus49(int reps) {
      List<Integer> dummy = null;
      for (int i = 0; i < reps; i++) {
        dummy = c6aus49();
      }
      return dummy;
    }

      }
      return dummy;
    }
  }
 
  public static void main(String[] args) {
    System.out.println("a6aus49() = " + a6aus49());
    System.out.println("b6aus49() = " + b6aus49());
    System.out.println("c6aus49() = " + c6aus49());
    System.out.println("d6aus49() = " + d6aus49());
   
    Runner.main(LottoTest.class, new String[0]);
  }
 
  public static ArrayList<Integer> a6aus49() {
    Random r = new Random();
    ArrayList<Integer> ali = new ArrayList<>();
    while (ali.size() < 6) {
      int i = r.nextInt(49) + 1;
      if (!ali.contains(i)) {
        ali.add(i);
      }
    }
    Collections.sort(ali);
    return ali;
  }
 
  public static ArrayList<Integer> b6aus49() {
    Random r = new Random();
    HashSet<Integer> hsi = new HashSet<>();
    while (hsi.size() < 6) {
      hsi.add(r.nextInt(49) + 1);
    }
    ArrayList<Integer> ali = new ArrayList<>(hsi);
    Collections.sort(ali);
    return ali;
  }
 
  public static ArrayList<Integer> c6aus49() {
    Random r = new Random();
    TreeSet<Integer> tsi = new TreeSet<>();
    while (tsi.size() < 6) {
      tsi.add(r.nextInt(49) + 1);
    }
    ArrayList<Integer> ali = new ArrayList<>(tsi);
    return ali;
  }
 
  public static ArrayList<Integer> d6aus49() {
    Random r = new Random();
    ArrayList<Integer> ali1 = new ArrayList<>();
    ArrayList<Integer> ali2 = new ArrayList<>();
    for (int i = 1; i <= 49; i++) {
      ali1.add(i);
    }
    for (int i = 0; i < 6; i++) {
      ali2.add(ali1.remove(r.nextInt(ali1.size())));
    }
    Collections.sort(ali2);
    return ali2;
  }
}

Resultat ist:

Zu dem Fehler: Anscheinend passt deine com.google.guava Version nicht zu der Lib.

Moin, bei mir funktioniert es auch mit Rückgabewert nicht (ebenfalls 0.5-rc1):

Wie hast du dir Caliper gezogen? Git/Maven?
