Perlu bantuan ngumpulake paket

Halo kabeh. Aku sinau Eckel, nyoba kanggo mangerteni kompilasi paket, nanging conto ing buku kasebut diterangake kanthi ora apik, aku durung nemokake informasi sing apik ing Internet, mula aku takon karo guru ing kene, apa masalahe. .
Umumé, ana folder akses, ing kono ana file LibTest.java, isine:

//: access/LibTest.java // Uses the library. import net.mindview.simple.*; public class LibTest { public static void main(String[] args) { Vector v = new Vector(); List l = new List(); } } /* Output: net.mindview.simple.Vector net.mindview.simple.List *///:~ Ing tingkat sing padha karo folder akses ana paket net / mindview / prasaja, ing folder prasaja ana List file. java

//: net/mindview/simple/List.java // Creating a package. package net.mindview.simple; public class List { public List() { System.out.println("net.mindview.simple.List"); } } ///:~ lan file Vector.java

//: net/mindview/simple/Vector.java // Creating a package. package net.mindview.simple; public class Vector { public Vector() { System.out.println("net.mindview.simple.Vector"); } } ///:~ File Vector.java lan List. java kompilasi biasane, nanging nalika aku nyoba kanggo ngumpulake LibTest.java aku njaluk kesalahan LibTest.java:3: kesalahan: paket net.mindview.simple ora ana
aku. nyoba kompilasi karo perintah sing beda-beda, contone variabel Lingkungan disetel, path C:\Program Files ditambahake kanggo Path \Java\jdk1.7.0_60\bin, D:\Work\Java\stud ditambahake kanggo CLASSPATH Apa salahku , kok compiler ora narik munggah file paket, kaya aku ngerti, iku kudu katon ing CLASSPATH?

javac LibTest.java
javac -classpath . LibTest.java
javac D:/Work/Java/stud/access/LibTest.java
