java8 两个List对象合并和List的转换成Map List转成成Map 1 2 3 4 5 6 publicstaticvoidmain(String[] args) {<br> List<String> idList =newArrayList<>(Arrays.asList("姓名","性别")); List<String> nameList =newArrayList<>(Arrays.asList("杰克","男"));<br> Map<String,String> listMap = ...
Map<String,String> collect1 = gradeClassList.stream().collect(Collectors.toMap(GradeClassRelation::getGradeName+GradeClassRelation::getClassName, VerifyStudentCodeVo::getClassName)); 但是发现不行,提示了如下错误。 后来改成了如下: List<GradeClassRelation> gradeClassList = iSchGradeService.getGradeClass...
Java8中将两个l..百万以下迭代遍历快,7楼的两万以下跟8楼一样,两万以后贼慢,8楼的整体可以,百万以上速度跟百万以下速度差别不大。但是迭代遍历百万以下快于流
后台的两个list ..dataType:'json',success:function(data){ var list1 = data.mapkey; $(datas).each(funct
