Need guidance with small program... Beginner Java Programming

Question

Hey guys im new to Java... Im currently a high school student and we've been learning java for a while now.
I am currently doing an out of class assignment meaning im doing it for my own benefit since programming is my future job and passion and love, haha.
I recently bought the Head First Java 2nd edition and need to do this following program:
Expected output:
%java EchoTestDrive
helloooo...
helloooo...
helloooo...
helloooo...
10
My following code:
public class Echo
int count = 0;
void hello(){
System.out.println("helloooo... ");
public class EchoTestDrive
public static void main(String [] args){
Echo e1 = new Echo();
Echo e2 = new Echo();
int x = 0;
while( x < 4 ){    
/** We want this to be 4 so it loops around 4times to get (hello... ) x 4 ? - in the out put? */
e1.hello();
e1 = e2;
if( x==4){
e2.count = e2.count + e1.count;
x = x + 1;
System.out.println(e2.count);
My output:
helloooo...
helloooo...
helloooo...
helloooo...
0 <--- I am unsure what I am doing wrong because I cant seem to get this number to change at all....
Their template ( It was a fill in the blank ):
public class EchoTestDrive
public static void main(String [] args){
Echo e1 = new Echo();
int x = 0;
while(_________){
e1.hello();
if(___________){
e2.count = e2.count + e1.count;
x = x + 1;
System.out.println(e2.count);
class ________ {
int______ = 0;
void ______ {
System.out.println("helloooo... ");
Thanks fellow programmers and thanks for the assistance. To a bright future! :)
P.S. Is there a tip to figure out how to read the following output or what you will get without using the computer? It will be very helpful if you can describe what each part is doing.

Answer 1

public class Echo
    int count = 0;
    void hello(){
        System.out.println("helloooo... ");
public class EchoTestDrive
   public static void main(String [] args){
       Echo e1 = new Echo();
       Echo e2 = new Echo();
       int x = 0;
       while( x < 4 ){
           e1.hello();
           e1 = e2;
           // I intended to use this code because e1 is referring the Class Echo ->"hello()"
           // in the code above.  I was intending to make them both refer to that.
           // This way it print hello... 4 times when it goes in the loop.
           e1.count = e1.count + 1;
       if( x==4){
           e2.count = e2.count + e1.count;
        x = x + 1;
    System.out.println(e2.count);
