How to set ClassPath of Java?

Hi, there. I’m new to Linux, especially to Manjaro. I’m learning Java. And I just wanna set ClassPath. There are a lot of content to set it on Google. But they are not for manjaro. Please help me out. Now I don’t have ClassPath for Java on my pc. How can I create it, use it and then modify it?
If there’s a complete guide about it. Please share with me.

You mean something like path and classpaths ?
