Java 編譯器 Javac 參數列表

-sourcepath 告訴編譯器原始碼所在位置
-d 指定編譯完成的位元碼(.class) 存放的資料夾
-verbose 輸出編譯的過程
-classpath 告訴編譯器到何處尋找先前已編譯好的位元碼存放位置
-source 檢查使用語法是否有超過指定的版本號
-target 指定編譯出來的位元碼，符合指定平台允許的版本號 (-target 必須大於等於 -source)
-bootstrap 指定類別載入器，搭配source與target使用，類別載入器會參考到rt.jar，可避免因為舊版JRE沒有新API造成無法執行的情形。
-version 執行版本資訊


範例
javac -sourcepath src -d classes src/Main.java

說明
使用java編譯器javac，編譯src/Main.java，到sourcepath指定的src目錄下尋找有用到原始檔，編譯完畢將檔案放置在classes目錄下
