Java如何在使用命令行编译时添加库或API？

Question

问题说明了一切，我试图在我的代码中使用外部库，但它告诉我我引用的包不存在，所以我猜导入不起作用。我该怎么做呢？

Answer 1

使用 -cp 选项，如 javac notes 中所述.

Specify where to find user class files, and (optionally) annotation processors and source files. This class path overrides the user class path in the CLASSPATH environment variable. If neither CLASSPATH, -cp nor -classpath is specified, the user class path consists of the current directory. ..
