Posted by: wes109 Posted on: 2010-07-06 15:28 这种培训就是一个愿打一个愿挨，你改变不了 如果站在招到合适人的角度，建议你直接开8k以上薪水，绝大部分这种连投简历的勇气都没有啦 如果就给个4～5k，那你就慢慢忍受吧。时间一久，变成享受，也未可知。。。 | |

Posted by: JiafanZhou Posted on: 2010-07-07 19:34 > 但全部TMD连容器都不会选....我现在才知道3年经验的 In my opinion, a good software architect or senior engineer needs to know which JEE container to use in the project. Not only that, they need to compare the difference between various containers, knowing the cons and pros of each and most importantly making a decision to choose one and document them by writing them down. 3 years experience is considered a junior engineer in my opinion, so don't be serious on this. haha > 不知道什么时候用HashMap什么时候用ArrayList的多得去了. wow...... How can somebody know to solve a complex maths problem without knowing numbers 1 2 and 3? I don't understand this. HashMap and ArrayList are the most important data structure in computer programming. (not only in Java).

Posted by: ditty Posted on: 2010-07-08 10:52 ssh？也许是开发经验和你所需的技术领域不同吧？ 对于一个写了3年shell的人，你问他HashMap和ArrayList的区别，不知道也正常。

Posted by: JiafanZhou Posted on: 2010-07-08 17:52 cxp 108, sorry for my misunderstanding your term. If you refer to the Collections, then I will be probably in the same position as how you are so disgruntled by these interviewees who have a bare understanding of the Collections. And if I would use one word to describe Java Collections, it will be *FOUNDATIONS*. Java gives the package name as "java.util" to include Collections and they probably exist from the first version of Java. Every Java book describes ArrayList and HashMap in details, so there will be no excuse if someone is not familiar with them. Except for those shell developers who do not really need a data structure to store data  Since this is a technical forum, let's talk some technical aspect of HashMap and ArrayList. You can very easily see my "geek" personality from this thread. Your question translated into English might look like this: "Between ArrayList and HashMap, which data structure is faster to iterate over all the elements?" Correct me if I am wrong, but I also feel that it is a strange question to be asked in an interview. Why? ArrayList is an implementation of List which is generally used as a dynamic array to store in a pre-determined order. HashMap is an implementation of Map which we need to efficiently retrieve items by some sort of look-ups, that is retrieving something based on the key. (most use case are caches in light of my own experience). In other words, we use Map as an indexing data structure and use List as we would usually use fixed arrays. So I will not really compare their performance in respect of the iterations but the usage of these two widely used data structure in lieu. To answer your question, which one is faster to iterate over all elements? I believe the answer is the same. I always think of ArrayList as a number of boxes lined up against the wall and numbered from 1 to N. Whereas thinking of a HashMap as a room of boxes assigned randomly with a key-value with a keeper at the door. Ask the door keeper for the box labelled "xyz" (key) and he will go and find the box and returns you the content (value). But if iterating over all the elements in ArrayList and HashMap, they all need to take N steps where N is the number of the elements. So in my opinion, would it be better that the comparison is between *HashSet* and *ArrayList*? And analyse the performance including the Add, Update, Delete and Find.

Posted by: YuLimin Posted on: 2010-09-14 17:59 感叹。。。 我认为关键的问题不在于他们懂还是不懂，关键在于他们是否掌握如何分析与思考问题的能力，二是否有“钻”进去的学习动力？其他的能力可以顺利通过以上两点而达成。 | |
