Using libraries in NetBeans 6.1

Question

Suppose you have two classes that are in separate files but the same package. In order for one class to access the other that it references that is in the same package, what do you need to do? What I did was add the project that contains the referenced class to the Libraries folder (listed under the Projects tab) that's inside the file in which its referenced. I don't understand why I needed to do this since both classes are in the same package (and in the same directory). I believe I created the project files correctly because for each file I selected New Project, then Class Library, and I clicked on the Source Packages tab under the Projects tab and added a new Java package...The code for the two classes are listed below (Note, I don't know if this would make a difference, but the IDE I used is NetBeans 6.1):
//: innerclasses/controller/Event.java
// The common methods for any control event.
package innerclasses.controller;
public abstract class Event {
  private long eventTime;
  protected final long delayTime;
  public Event(long delayTime) {
    this.delayTime = delayTime;
    start();
  public void start() { // Allows restarting
    eventTime = System.nanoTime() + delayTime;
  public boolean ready() {
    return System.nanoTime() >= eventTime;
  public abstract void action();
} ///:~
//: innerclasses/controller/Controller.java
// The reusable framework for control systems.
package innerclasses.controller;
import java.util.*;
public class Controller {
  // A class from java.util to hold Event objects:
  private List<Event> eventList = new ArrayList<Event>();
  public void addEvent(Event c) { eventList.add(c); }
  public void run() {
    while(eventList.size() > 0)
      // Make a copy so you're not modifying the list
      // while you're selecting the elements in it:
      for(Event e : new ArrayList<Event>(eventList))
        if(e.ready()) {
          System.out.println(e);
          e.action();
          eventList.remove(e);
} ///:~Similarly, how do you import the library innerclasses.controller other than writing "import innerclasses.controller;?" I did the same as listed above (adding the two project files above that are from the same package to the Libraries folder that's inside the file).
Thanks in advance!

hi it is unlikely people will answer you here because it is about netbeans. this is a java site so they will probably tell you to go to a netbeans site. the one i use is nabbles netbeans just do a search on google to find it.
you might get lucky here but i doubt it because most people here use notepad and run programs from command prompt. so they might not even know anyway. also i think there is a tutorial at the netbeans sites about transfering libraries they tell you how in some of the introductory tutorials. i think one of the tutorials in relation to setting up a database using derby shows you how to do it but i can't remember.
your best bet is nabble good luck.
