無法將Netbeans生成的.java文件編譯到命令行上的.class中

我構建了我的java程序作爲uni任務的一部分，並且作爲提交的一部分，它必須能夠在DOS窗口中編譯和運行（讀取Windows命令窗口）。該程序在Netbeans中運行正常，但是當我將所有.java文件複製到單獨的文件夾並嘗試編譯每個文件時，我會遇到大量的編譯錯誤。當我在Netbeans中創建這些文件時，我將它們全部包含在一個包中，並讓Netbeans在每個類的頂部添加一個「包* Project_Name *」。其餘的是標準的Java，沒有太複雜的。我第一次使用Netbeans（版本7.1.1是我正在使用的），它讓我瘋狂。我可以創建一個.jar文件，我可以從命令行運行它，但我需要能夠顯示源代碼可以從命令行編譯，並且生成的文件也可以從命令運行線。有沒有其他人有這個問題，如果是的話，你是如何克服它的，或者沒有人知道如何解決這個問題。無法將Netbeans生成的.java文件編譯到命令行上的.class中

我有一種感覺與其他文件的引用有關，因爲大多數錯誤都與創建的對象和從其他文件調用的方法有關。例如，我有一個Manager.java文件，該文件具有Manager對象的構造函數和方法，然後在另一個文件（比如Proprety.java）中有我使用new關鍵字創建Manager對象的代碼。

使用當前CLASSPATH Im爲

CLASSPATH =; C：\ Program Files文件\的java \ jdk1.7.0_03 \ lib中; C：\ Program Files文件\爪哇\ JRE6 \ lib中\分機\ QTJava.zip ;

PATH變量的設置類似於

...; C：\ Program Files文件\的Java \ jdk1.7.0_03 \ BIN; C：\ Program Files文件\的Java \ jre7 \ BIN

而且而已。我使用的唯一庫是java.util。*和java.io. *所有其他參考都是我在Netbeans中創建的類文件

任何幫助都會真正被理解。 SET命令的

你設定一個適當的類路徑？你並沒有真正提供任何我們可以用來幫助的實際信息。 – 2012-04-02 12:17:51

你應該包含一些關於使用類的基本信息。你設置了正確的類路徑嗎？你使用庫嗎？ – dexametason 2012-04-02 12:19:17

好吧，我認爲，關鍵這裏是：

我將它們全部包含在一個包中，讓Netbeans在每個類的頂部添加一個「package * Project_Name *」。

而且你的命令編譯：

javac Manager.java

假設你的包名projectname。然後Netbeans創建了一個目錄projectname，並將其中的所有Java文件Manager.java，Property.java等放在其中。

在Java中，包結構直接對應於文件系統中的目錄結構。例如。如果您在包x.y.z中包含類A，則類A的源代碼文件位於文件x\y\z\A.java中。

因此，當您複製所有的*.java文件時，您必須確保也複製原始目錄結構。在你的情況下，你可以複製你的類Manager.java,Property.java，...到C:\test\projectname。然後在你的DOS窗口cd到該目錄，並編譯類：

javac -cp .. Manager.java

的-cp ..命令行選項的意思是，你的包/目錄結構的根是一個級別的C:\test。然後，在編譯Manager.java時，Java編譯器找到對類Property的引用，並且它假定類Property與類Manager處於相同的包中。所以編譯器正在尋找類projectname.Property。當-cp選項指向C:\ţest時，編譯器知道它應該查看目錄C:\test\projectname。

編譯就可以運行你的程序後：

java -cp .. projectname.Manager
