这套面试题主要目的是帮助那些还没有java软件开发实际工作经验，而正在努力寻找java软件开发工作的朋友在笔试时更好地赢得笔试和面试。由于这套面试题涉及的范围很泛，很广，很杂，大家不可能一天两天就看完和学完这套面试宝典，即使你已经学过了有关的技术，那么至少也需要一个月的时间才能消化和掌握这套面试宝典，所以，大家应该早作准备，从拿到这套面试宝典之日起，就要坚持在每天闲暇之余学习其中几道题目，日积月累，等到出去面试时，一切都水到渠成，面试时就自然会游刃有余了。

答题时，先答是什么，再答有什么作用和要注意什么（这部分最重要，展现自己的心得）

答案的段落分别，层次分明，条理清晰都非常重要，从这些表面的东西也可以看出一个人的习惯、办事风格、条理等。

要讲你做出答案的思路过程，或者说你记住答案的思想都写下来。把答题想着是辩论赛。答题就是给别人讲道理、摆事实。答题不局限于什么格式和形式，就是要将自己的学识展现出来！

别因为人家题目本来就模棱两可，你就心里胆怯和没底气了，不敢回答了。你要大胆地指出对方题目很模糊和你的观点，不要把面试官想得有多高，其实他和你就是差不多的，你想想，如果他把你招进去了，你们以后就是同事了，可不是差不多的吗？

关于就业薪水，如果你是应届生，那不能要高工资，好比大饼的故事，没有文凭还想拿高工资，就去中关村缺什么补什么吧！少数人基础确实很好，在校期间确实又做过一些项目，那仍然是可以要到相对高的工资的。

知无不言，言无不尽。

百思不得其解时，请理想思维，把小变成大做，把大变成小做，

答案：
A: select distinct name from score where name not in (selectdistinct name from score where score<=80)

B:select distincename t1 from score where 80< all (select score from score where name=t1);
