Having problem with Classpath, lead to more problem [message #1830483]

It seems like the classpath is missing, trying to figure out how to solve this problem. I would appreciate if someone can help me. The initial problem I was having with something else, "Could not find or load main class" when I did something in the build path.

I have solved the issue. However, the problem now here is, I am trying to add my existing java files into a new package. I do not know how to import java files into new package. When I try to run it say

Exception in thread "main" java.lang.Error: Unresolved compilation problem:

at ss/ss.Add.main(Add.java:6)

What I tried to do was, copy my java files from the other package and paste into the new package in bin folder

The package structure declared in your *.java files must mirror exactly the folder structure in the file system. Above you have the *.java file in the root "src" folder, but it declares a package name so must be in src/com/<...>. Note that it's bad style to name packages with upper case names.

The structure wasn't like this, I made an mistake, I believe what I had done was change the build or refactor. How would I go about this?

I'm really not sure how you got into this state. Certainly on the first page of the Java project wizard I would choose "Create separate folders for sources and class files". It's probably better to start from scratch. On the src folder, the context menu will have things like New -> Class and New -> Package which will create the correct structure.
