谢谢        我先前是这样的
/*if(oneList != null) {
                    for (int q = 0; q < oneList.size(); q++) {  //1级
                        StringBuffer sb = new StringBuffer();
                        sb.append(oneList.get(q));
                        if(twoList != null) {
                            for(int j = 0; j < twoList.size(); j++) {   //2级
                                sb.append(twoList.get(j));
                                if(threeList != null) {
                                    for(int k  = 0; k < threeList.size(); k++) {     //3级
                                        sb.append(threeList.get(k));
                                        System.out.println(sb.toString());
                                    }
                                }
                            }
                        }
                    }
