推荐答案

什么是外部JAR？

• 外部名称建议是未构建的Jar文件通过当前开发的代码。它是一个实用的Jar文件，外部添加了额外的功能。它可以是从外部站点提供的一个API Jar文件，就像在你的情况下，3个Jar文件将会调用External Jar Files。



• 添加外部jar文件在Eclipse中，请按照下列步骤操作：右键单击项目 - >选择构建路径 - >在以下对话框中选择配置构建路径 - >库选项卡。

  What is an External JAR?

  • External as the name suggest is a Jar file that is not built by the currently developing code. It is a utility Jar file that is added externally for extra features. It could be an API Jar file provided from the external site, just as in your case the 3 Jar files will be going to call External Jar Files.

  • To add an External Jar file in Eclipse, follow these steps: Right Click on Project -> Select Build Path -> Select Configure Build Path -> Library Tab in the following Dialog box.

    图书馆是JDK目录或任何其他软件的内置Jar文件，例如J2ME-波兰语，如上图所示。通常这些库文件由制造商开发。

    A Library is a in-built Jar file from the JDK Directory or any other software e.g. J2ME-Polish as you can see in the Image above. Normally these Library files are developed by a manufacturer.

    
    
    • 添加Jar文件：当您在Eclipse中有多个项目，并添加另一个项目的Jar文件时，称为添加Jar文件。上图中有一个第一个Button，它只允许你从另一个Project添加Jar文件。
    
    
    • 添加外部Jar：添加站点或其他制造商提供的API Jar文件时。在你的情况下，3个Jar文件是External Jar Files。您可以通过使用第二个按钮添加外部JAR来添加。
    
    

    • 添加库：单击第4个按钮将打开如下对话框。

    • Adding Jar File: When you have more than one project in Eclipse and you add another project's Jar file, that is called adding Jar File. There is a first Button in the Photo above, it only allows you to add Jar file from the other Project.
    • Adding External Jar: When you add any API Jar file provided by the site or another manufacturer. In your case the 3 Jar files are External Jar Files. You can add then by using second Button "Add External JARs".

    • Adding A Library: Clicking on the 4th Button will open a dialog box as below.

    您可以在系统中添加不同的库。您还可以通过选择用户库添加您自己的库。

    You can add different libraries installed on your system. You can also add your own Library, by selecting "User Library".
