I am trying to execute a program from the command prompt. I type java -jar zuul.jar (zuul is the name of my project) and I get a message that java is not recognized as an internal or external command. What do I do wrong?

I am operating java from the command line (using Terminal on Mac OSX 10.9.5).The current directory within Terminal is called "orange" and the following sourcecode file is in the orange directory :
Test1.java
package orange;
public class Test1 {
public static void main(String[] args) {
System.out.println("Test1 works");
}
}
This complies to Test1.class (visible in the orange directory) but when I try to run it in Terminal (simply using "java Test1" from within the orange directory). I get the following error message (which I don't get if I simply comment out the line //package orange;)
Exception in thread "main" java.lang.NoClassDefFoundError: Test1 (wrong name: orange/Test1)

I have set the CLASSPATH
(C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53libservlet-api.jar,
PATH(C:Program FilesJavajdk1.7.0_51in)
and JAVA_HOME
(C:Program FilesJavajdk1.7.0_51) environmental variable on my windows XP.
I installed tomcat server and its running fine. I made my first servlet(DemoServlet.java) in
C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53webappsDEMOWEB-INFclasses folder.
I made the XML file (web.xml) in C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53webappsDEMOWEB-INF folder. In command prompt I went to the classes folder
(C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53webappsDEMOWEB-INFclasses).
And tried to compile my servlet(javac DemoServlet.java) but it is showing file not found error. I am new to servlets.

I was wondering if their is an easily explainable way to convert a jar for a text-based game that runs off the command prompt into a executable. I would guess there probably is not and the game would have to run off of completely different commands, but I thought it couldn't hurt to ask.

I just created a Hello World program in Notepad, but command prompt still can't find it even when ran as administrator. I've even tried to use command line to run Hello World programs I've created with Eclipse but it still doesn't work. Here's proof I have JDK setup as PATH:
I've even tried having the JRE as path but that still doesn't solve my problem. I'm really trying to learn Java programming but this problem is holding me back.

So say I write up a program like a dice roll game, which I see on the forums here. It's all written and good to go and when I hit Run it does what I want it to do, no errors..What do I do with those .class and .java files? Do I compile it somehow into an app I can put on the google play store? What is the NEXT STEP after the program is all written?

I get quite a few errors while trying to compile the BeerSong from the Head First Java book. I copied the text from another person that did the beer song on this forum and it worked as expected. What I can't figure out is why mine is not working when it looks like the text is exactly the same between the two versions. His works, but mine doesn't.
Here is the text and errors that I get:
public class BeerSong
{
public static void main (String[] args)
{
int beerNum = 99;
String word = "bottles";

Create a class named Commission that includes three variables: a double sales figure, a double commission rate, and an int commission rate. Create two overloaded methods named computeCommission (). The first method takes two double parameters representing sales and rate, multiplies them, and then displays the results. The second method takes two parameters: a double sales figure and an integer commission rate. This method must divide the commission rate figure by 100.0 before multiplying by the sales figure and displaying the commission. Supply appropriate values for the variables, and write a main () method that tests each overloaded method. Save the file as Commission.java
b. Add a third overloaded method to the Commission application you created in Exercise 1a. The third overloaded method takes a single parameter representing sales. When this method is called, the commission rate is assumed to be 7.5% and the results are displayed. To test this method, add an appropriate call in the Commission program's main () method. Save the application as Commission2.java
COMMISSION.JAVA
public class Commission
{
public static void main(String[] args)
{
double Sales = 10000;
double commRate = 0.075;
int rate = 7;
computeCommission(Sales, commRate);
computeCommission(Sales, rate);
}
public static void computeCommission(double Sales, double commRate)

I am watching BrandonioProductions on youtube. His videos are pretty good, but he doesn't seem to get errors where I get them. Here is an example.
public class compareUnequal {
public static void main(String[] args){
compareTwo();
}
public static void compareTwo(){
String x = "david";
String y = "Notdavid";
if (!x.equals(y)){
System.out.println("Not equal");
}
}
}
It runs ok, but asked me to proceed when there is an error, but I can`t figure out where the error is!

I am trying to create an array where each object includes a service description, price, and time in minutes. I have a Service class and a SalonReport class:
import java.util.*;
public class Service
{
public String serviceDescription;
public double servicePrice;
public int timeMinutes;
[Code] ....
When I compile this, I get an error message that says:
SalonReport.java:8: error: constructor Service in class Service cannot be applied to given types;
salonServices[0] = new Service("Cut", 8.00, 15);
^
required: no arguments
found: String,double,int
reason: actual and formal argument lists differ in length
What this error message means and how I can correct it? I am confused because my SalonService() method has (String service, double price, int minutes), and each object is listed in that exact order.
