How to call an unpackaged class under a packaged class

xenon1

The manufacturer only provides all compiled class files (no package), and my existing program has packages.

The current situation is that the compiled unpackaged class file can only be called by placing the calling code in the root directory, and it is always not compiled when the code is placed in a class under the package.

How do heroes solve this problem? Thank you.

Not in the same directory, of course, you can't call it. The manufacturer does not provide a package, you package it yourself.
After packaging, add it to the CLASSPATH and import it.

Add the directory where the class files are located to the CLASSPATH. Such as C: /a/b/c.class
CLASSPATH =% CLASSPATH%; c: / a / b /

Add the path of the unpackaged class to the classpath in the environment variable.

Type into a .jar file, and then import the .jar file for compilation.

Classes without packages can cause problems
And problems don't occur often.

I don't think I can ask them to add a package and compile it again.

Or first specify the specific path of these classes at compile time.

It seems that classes in the root directory cannot be referenced
May be a Java bug, import does not support root directories


But generally there is no such requirement

Seems to be unquotable

java bug

But it ’s not necessary.

Add the directory where the class files are located to the CLASSPATH.
