I have list List<Long> list , that contains: [160774, 7212775] and Long id = 7212775 . I need to check if the list contains an element with value of id . How to do that? Unfortunately list.contains(id) returns false in my case. I'm using it that way: @RequestMapping("/case/{id}") public String openCase(@PathVariable("id") Long id) { log.debug(caseDAO.findAllCasesId()); // [160774, 7212775] log.debug(id); // 7212775 if(caseDAO.findAllCasesId().contains(id)) { return "case"; } else { return "404"; } } Piece of DAO (Hibernate, but native sql here): public List<Long> findAllCasesId() { String sql = "select id from cases"; SQLQuery query = getSession().createSQLQuery(sql); return query.list(); } SOLVED The problem was with caseDAO.findAllCasesId() , that return list of Object , not list of Long . I corrected this by: SQLQuery query = getSession().createSQLQuery(sql).addScalar("id", Hibernate.LONG); Big thanks to: Nayuki Minase
