For instance: In Navigator, I create a new project "tryUtility", in it I create a new package "main". Into this package I copy a class HelloInt.
package main;
public class HelloInt { public static void main(String[] args) {
System.out.println(IntegerFormatter.format(334928,14));
}
}
My Eclipse directory is C:\B\E\ Elsewhere I have a directory C:\temp\utility which contains IntegerFormatter.java, a utility which I want to use.
In Navigator, I right click on project tryUtility. Then Properties > Libraries > Add Class Folder > Create New Folder > Advanced > Link to folder in file system > Browse ...
I select C:\temp\utility, and back in the New Folder dialog type "bob" in the Folder name text field. I click OK, then OK again.
Then, back in the "Properties for tryUtility" dialog, the OK button is
disabled. An error message near the top of that dialog says
"Cannot nest 'tryUtility/bob' inside 'tryUtility'. To enable the
nesting exclude 'bob/' from 'tryUtility'." For your enjoyment I'll try to attach a gif of that dialog window. I am having fun, and hope you can have fun too.
