不知道自�׃ؓ什么会如此痴迷于Java�Q�或者更应该说是�~�程。现在已�l�大三了�Q�有了两�q�多的Java�l�验�Q�虽然不长，但学到的东西很多。这主要归功于对Java的热��p��有我的英语。嘿嘿，本�h初中在英国年的，所以英语还���不错，看文档和书籍都是英文原版的，所以得到的信息更多�?BR><BR>&nbsp;&nbsp;&nbsp; 刚到大学时对�~�程一无所知。大学里教的语言是C++�Q�刚接触时死�z�都弄不明白指针�Q�每�ơ编�E�时都回遇到�q�样和那��L��指针问题�Q�最常见的就是指针�ؓ�I�的情况�Q�郁闯����?IMG height=20 src="http://www.aygfsteel.com/Emoticons/hitwall.gif" width=25 border=0>。大概是大二上学期某个时候，�H�然在图书馆看到关于Java的书�c�，看了几页���已�l�着�q�了。接着的两�q�多里，我不断的学习Java�Q�从最开始的环境变量的配�|�（大家必须承认�Q�这是Java初学者的最大问题）�Q�到现在已经熟悉J2EE�Q�Java EE�Q�，包括目前���行的Web框架和一些比较有用的开源工��P��比如Ant、JUnit、WebUnit的等�{��?BR><BR>&nbsp;&nbsp;&nbsp; 我买的第一本Java书是Deitel两�h写的“Java How to Program”。我很庆�q怹�了这本书�Q�这是本很好的初学书�c�，所以现在如果有人问我刚开始学Java应该用什么书�Q�我会推荐他�q�本�Q�当然前提是要看得懂英文<IMG height=19 src="http://www.aygfsteel.com/Emoticons/regular_smile.gif" width=19 border=0>。之后又随之��C��Java Advanced How to Program�Q�虽然这本书是老了一点，但是也很有用�Q�给我奠定了较好的J2EE基础�?BR><BR>&nbsp;&nbsp;&nbsp; 学习J2EE大概是在我接触Java一�q�多后开始的�Q�那时我对开源还不懂�Q�所以以为J2EE只有Servlet、EJB和JSP。之前我一直��用的是Ant和Editplus�Q�现在有时也用，Ant���实是一门非常好的工兗���做J2EE开发就不能只��用Ant了，我回抓狂的。IDE最开始我选择了Netbeans�Q�刚开始觉得很好用�Q�很方便�Q�但随着我做的东西的规模变大�Q�机器就开始卡了（Netbeans很消耗内存的�Q�。之后在�|�上看到Eclipse很流行，便下下来用，���q����C��现在�?BR><BR>&nbsp;&nbsp;&nbsp;

说说未来吧，我已�l�大三了�Q�还有一�q�就要毕业，我准备出国。开始准备去英国�Q�因为环境熟悉，�q�选了一所英国计算机排名第三的“帝国理工（Imperial College�Q�”。去英国���p��考雅思。后来大家还是推荐我�ȝ��国，毕竟���国在计���机斚w��是老大。我又看中了卡耐基·梅隆�Q�这所学校��׃��用介�l�了吧，李开富的母校~~~~ �ȝ��国要考托���和GRE。这下我三门都要考，托福和雅思我不怕，托福我刚做了�?003�q�的卷子�Q�只错了4道题�Q�也许有一点运气吧�Q�但应该�q�算不错了。最怕的���是GRE�Q�听说有些�h因�ؓGRE��Z���?IMG height=19 src="http://www.aygfsteel.com/Emoticons/confused_smile.gif" width=19 border=0>�Q�恐怖啊。我也渐渐感觉到了GRE的难度�?BR>&nbsp;&nbsp;&nbsp;
