Java实现双色球抽奖随机算法示例

class myLuck {      private int mTarget;    List<Integer> mNums = new ArrayList<Integer>(); //摇奖池    ///从多少个数中产生多少个数  ///例如 33选6 则Source=33，Target=6；  myLuck(int vSource,int vTarget) {        for (int i = 1; i <=vSource ; i++) {            mNums.add(i);    }    mTarget=vTarget;  }    public String GetNums()  {        String xString="";    for (int i =0;i<mTarget; i++)     {      int _index=(int)(Math.random()* mNums.size());      xString+=mNums.get(_index)+" ";      //System.out.print("("+(_index+1)+")"+mNums.get(_index)+"-");        //如何删除一个元素      mNums.remove(_index);    }      return xString;  }  }

myLuck _red=new myLuck(33, 6);  myLuck _blue=new myLuck(16,1);String Str =_red.GetNums() +"，"+_blue.GetNums();
