我只有一個(gè)打字母小游戲
《java2 核心技術(shù)》卷 I，II， 卷I是基礎(chǔ)部分（包括java 基本語法，面向?qū)ο?，IO流與文件，圖形界面,applet, 異常處理，范型設(shè)計(jì)），卷II是高級(jí)部分（多線程，集合，網(wǎng)絡(luò)，JDBC，分布式對(duì)象，高級(jí)圖形特性，JavaBean,安全，XML。。。）高手們說看完這兩本書，就可以看《Thinking in java》了，之后就可以去學(xué)J2EE了
PS: 其實(shí)學(xué)完基本語法，I/O，異常，集合，JDBC（當(dāng)然也要看看數(shù)據(jù)庫(kù)Oracle 或MySql, Sql server之類的）后就可以開始學(xué)J2EE了：JSP ，servlet， JavaScript(跟JAVA沒關(guān)系的一種腳本語言，用于B/S架構(gòu)網(wǎng)絡(luò)前臺(tái)處理數(shù)據(jù))，structs 等。。。對(duì)于JFC中的SWING圖形編程，如果覺得麻煩就跳過吧，畢竟桌面級(jí)開發(fā)不是JAVA的強(qiáng)項(xiàng)，非常麻煩。。。（寫一個(gè)什么都沒有的對(duì)話框就占去了14M內(nèi)存，那還有啥好說的。。。）
另外，《JAVA編程思想》（《Thinking in JAVA》的中文翻譯版）建議在看完核心技術(shù)I以后再看，對(duì)初學(xué)者而言，《JAVA編程思想》并不見得是本好書，但是對(duì)于有一定JAVA基礎(chǔ)的人來說，這本書就是一本好書
還有就是多練習(xí)，初學(xué)者建議使用記事本編輯程序，在控制臺(tái)下使用javac編譯程序, java運(yùn)行程序(這對(duì)你理解環(huán)境變量有幫助)，之后你可以使用eclipse進(jìn)行JAVA編程，需要說一點(diǎn)的是eclipse非常方便，它的快捷鍵堪稱一絕，不過對(duì)初學(xué)者不好，會(huì)慣壞你的，學(xué)完面向?qū)ο筇匦砸院笤偈褂茫ǔＳ每旖萱Ialt + /）。
書上的代碼很多，最好都敲一遍，對(duì)著書理解，其實(shí)你會(huì)發(fā)現(xiàn)，JAVA并不難（僅限與J2SE，因?yàn)楸救藙傞_始學(xué)J2EE，還不是很了解J2EE。。。）
