天啊，?冖_Na0?為什么會有我編的記事本代碼呢？？？呵呵……你肯定是“請教”過我的吧？？
成都創(chuàng)新互聯(lián)公司為企業(yè)級客戶提高一站式互聯(lián)網(wǎng)+設(shè)計(jì)服務(wù)，主要包括網(wǎng)站設(shè)計(jì)制作、成都網(wǎng)站建設(shè)、成都app軟件開發(fā)、重慶小程序開發(fā)公司、宣傳片制作、LOGO設(shè)計(jì)等，幫助客戶快速提升營銷能力和企業(yè)形象，創(chuàng)新互聯(lián)各部門都有經(jīng)驗(yàn)豐富的經(jīng)驗(yàn)，可以確保每一個作品的質(zhì)量和創(chuàng)作周期，同時每年都有很多新員工加入，為我們帶來大量新的創(chuàng)意。
呵呵……我自己編了一個，不過呢，沒有windows那么多的功能啊。

1、Eclipse - IBM甩出來給開源社區(qū)的IDE，其本身就是使用Java開發(fā)的。\x0d\x0a2、MyEclipse - 把Eclipse包裝了一下，加了J2EE企業(yè)開發(fā)的許多功能強(qiáng)大的插件。\x0d\x0a3、NetBeans - SUN公司自己開發(fā)的Java開發(fā)環(huán)境，功能挺多的。\x0d\x0a4、還有一些超喜歡手工編寫Java代碼的牛人喜歡使用帶語法著色功能的純文本編輯器編寫Java程序，代碼寫完后在命令提示符下編譯運(yùn)行。這種方式只適用寫少量代碼或作為學(xué)習(xí)使用，開發(fā)大型項(xiàng)目不適用，因?yàn)樾屎艿汀?/p>
