两个list集合循环，小的在外，大的在里，

[java]代码库

 
        Set<TemplateDetail> setTemplateChapterDetail = new HashSet<TemplateDetail>();
         for(int i=0;i<listChapterId.size();i++){
        	 TemplateDetail enTemplateDetail = new TemplateDetail();
			 enTemplateDetail.setChapterId(listChapterId.get(i));
			 //比例系数和章节id的顺序是相一致的
			 enTemplateDetail.setScoreRatio(listPerScore.get(i));
        	 for(int j=0;j<listDifficulty.size();j++){
        		int difficuly= Integer.parseInt(listDifficulty.get(j));
        		 enTemplateDetail.setDifficultyRatio(difficuly);
        		 for(int z=0;z<listQuestionId.size();z++){
        			 QuestionTypes questionType = new  QuestionTypes();
                	 questionType.setId(listQuestionId.get(z));
                	 enTemplateDetail.setQuestionType(questionType);
                	 enTemplateDetail.setQuestionTypeScore(Double.parseDouble(chapterDifficultyQuestionList.get(z)));
                	 setTemplateChapterDetail.add(enTemplateDetail);
        		 }
        	 }
