從eclipse 到IDEA 極簡入門
作為一個java開發工作者，工欲善其事必先利其器。我們經常用的就是eclipse 和 IEDA這兩個主流的開發工具。使用的一段時間，作為一個使用習慣eclipse轉化到IDEA需要知道什麼？
1，瞭解IDEA與eclipse之間概念區別
以是官方文件給出的區別，這樣就避免了我們在使用過程出現問題；
2，我們在寫程式碼經常會用到一些文字編輯的快捷，IEDA原生不做任何修改有如下的快捷鍵：

8，從eclipse工程匯入到IDEA
我們可以在開啟的歡迎頁面，點選 Import Project 匯入, 或者選擇 File | New | Project 匯入已經存在的原始碼。
如下我們要匯入的工程是maven工程或者是gradle工程可以如下圖進行匯入：
