Can't import a library

Question

A have folders test/labs/tryouts in E:....\exps and two .java files inside tryouts. The location is added into CLASSPATH: E:....\exps.

import test.labs.tryouts.*;

Doesn't work (it's hihlighted with red) and the use of described in .java files classes also fails:

Uncompilable source code - cannot find symbol
  symbol:   class Bullet
  location: class javaapplication1.Test1
at javaapplication1.Test1.main

What is wrong?

Are you sure that these are `.java` files and not `.class` files? — Pshemo, Jul 03 '16 at 21:39
This is unsolvable. Java does no "red highlights". What IDE do you use? Please read about minimal working sample in the guidelines on how to ask on SO. — thst, Jul 03 '16 at 21:40
@thst It's Netbeans. The red highlight says, there is no such a package. — parsecer, Jul 03 '16 at 21:43
Are you sure you've configured Netbeans with that Classpath? — sisyphus, Jul 03 '16 at 21:58

Most IDEs are using -cp or -classpath option to set classpath for each project which is

preferred over setting the CLASSPATH environment variable because you can set it individually for each application without affecting other applications and without other applications modifying its value

Problem with it is that

-classpath replaces the path or paths specified by the CLASSPATH environment variable while the tool runs: java, jdb, javac, javah and jdeps.

So try to add that path to your project rather than CLASSPATH. More info: How to setup classpath in Netbeans?
