From source file:Main.java

        dataList.add(i);//w  w  w.j a v a 2  s .c  o  m
    }
    Collections.shuffle(dataList);
    int[] num = new int[dataList.size()];
    for (int i = 0; i < dataList.size(); i++) {
        num[i] = dataList.get(i);
    }
    System.out.println(Arrays.toString(num));
