How can I import a custom package in IntelliJ IDEA (Java)?

问题

有一个叫做CLASSPATH的术语,它用于让JVM找到自定义类或jar文件并将它们导入到其他包中(我理解正确吗?)。所以,我创建了一些自定义类并将它们放到了net.ederika包中,然后我创建了另一个项目,命名为net.bartikan包。我的主要想法是将net.ederika包中的类导入到第二个项目中。我指定了CLASSPATH环境变量CLASSPATH EV,并将带有扩展名.class的文件添加到C:/DOC/JavaT net/edeirika/文件夹中。我得到了这个错误:导入包时的错误
我在这个过程中使用了IntelliJ IDEA。我的操作有什么问题吗?Bruce Eckel(《Java编程思想》一书的作者)写道,我们要指定CLASSPATH,然后将不带.class扩展名的文件夹添加到其中,JVM就会找到它们。我对这个主题感到非常沮丧和困惑,无法继续阅读那本书。来自《Java编程思想》。在互联网上关于这个问题的信息真的不多,因此我在这里提问。CLASSPATH指定的文件夹中的文件

英文:

There is such term like CLASSPATH which is using that JVM could find custom classes or jar files to import them to another packages (Am I right?). So, I created a few custom classes and placed them into package net.ederika, then I created another project with net.bartikan package name. My main idea is to import classes from net.ederika package to the second project. I specified CLASSPATH environment variable CLASSPATH EV and added to C:/DOC/JavaT net/edeirika/ files with extension .class. I got this: Error with package importing
I used IntelliJ IDEA for this. What's wrong with my actions? Bruce Eckel ("Thinking in Java" book) wrote that we specify CLASSPATH, add there folders with out .class files and JVM locates it. I'm really frustrated and confused with this topic and can't merely go on reading that book. From "Thinking in Java" There is no really much info about it on the Internet, thus I ask here. files in CLASSPATH specified folders
