Java-如何导入外部软件包? - java

我对Java还是比较陌生。我已经尝试寻找解决方案,但是我想我对Java的了解还不够,甚至不知道我应该寻找什么。

我想尝试语音识别,所以我下载了CMU的Sphinx-4源代码并进行了编译。一旦一切正常,我就可以运行包含的演示了。接下来,我在包含Sphinx-4目录的目录中为我的代码创建了目录(/ Jarvis /)。在Sphinx-4源目录中,有一长串目录指向我玩过的演示文件(/Sphinx4-1.0beta6/src/apps/edu/cmu/sphinx/demo/)。在demo文件夹中是一个HelloWorld目录,其中包含用于使用Sphinx-4函数的简单程序的源代码。我的首要目标是在自己为自己的代码设置的目录中获取此演示的副本。因此,我制作了HelloWorld文件的副本,并将其放置在我的Jarvis目录中。重命名并更改了代码,使以前是HelloWorld的所有内容现在变成了Jarvis。不幸的是,我遇到的问题并不像命名问题那么简单,而是找到软件包的路径。

对于Java,过去我只使用过一个简单的“javac example.java”命令来编译代码。我猜在这种情况下我可能还需要一些东西,但是我不确定到底是什么。当尝试以这种方式进行编译时,出现错误:

Jarvis.java:15: error: package edu.cmu.sphinx.frontend.util does not exist

12 errors

因此,我希望包括那些缺少的包裹。我知道这与代码中如何定义路径有关,但是我对Java的了解还不够,还不知道如何定义这些路径。我是否想在代码中进行更多更改?我应该以不同的方式执行编译吗?只要朝着正确的方向推进就很有用。

下面,我包括了4个文件,这些文件最初来自HelloWorld演示,我对其进行了微小的命名修改。

感谢您的时间!

参考方案

编译器使用“类路径”查找所需的库。设置类路径的方法有很多:一种是使用CLASSPATH环境变量,另一种是使用-classpath命令行开关。总之,您可以使用以下代码进行编译:

javac -classpath path/to/sphinx.jar jarvis/Jarvis.java

您可以在http://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.html中找到完整的文档

另一件事:Jarvis类声明它在一个名为jarvis.jarvis的包中,因此该类的完全限定名称为jarvis.jarvis.Jarvis……不确定您要使用的是什么。
