Lambda用法新特性遍历

studentList.forEach(str->
        {
            RecruitDict dict = new RecruitDict();
            dict.setDeleteFlag(0);
            dict.setStatus(6);
            dict.setName(str.getStatus());
            List<RecruitDict> list = recruitDictMapper.queryAll(dict);
            String identity = fzxyRegistStudentMapper.getIdentity(str.getIdentity());
            fzxyRegistStudentMapper.updateByStatus(str.getStatus(),list.get(0).getId(),str.getStudentName(),identity);
        }
);

@Test
  public void test66() {
      ArrayList<Girl> list = new ArrayList<>();
      list.add(new Girl("liubei","111"));
      list.add(new Girl("zhangfei","222"));
      list.add(new Girl("guanyu","333"));
      list.stream().map(n->n.getName())
              .forEach(n-> System.out.println(n));//这里打印的遍历的姓名

    List<String> collect = list.stream().map(n -> n.getName()).collect(Collectors.toList());
    System.out.println(JSONObject.toJSONString(collect));//这里是接受的姓名集合


}
