Hi
I am having problem compiling a java file Main.java which uses an object of another class, named Pet
I am using Netbeans 5.5 and I don't know where to put the class file Pet.class. I don't have Pet.java
No matter where I keep it the error message I get is
symbol : class Pet
location: class javaapplication8.Main
Pet MyPet = null;
Pet.class is product of Pet.java, that what you get once you compile your source code in java file.
Pet class can't be find because you are not calling that class properly, maybe mistake in spelling or your constractor is not right.
Can you please post your code, I think we will find more errors there
My code is as follows.
This is my Main.java
As you can see it is using the Pet object. But it says error in lines
Pet MyPet = null;
and
MyPet = new Pet();
I made a general java application using Netbeans 5.5.
I am much familiar with java but not net beans.
All I know is i have Pet.class which my application is not able to refer. So tell me where should I keep Pet.class so that, I have no compilation error.
import jpb.*;
public class Main
{
public static void main (String[] args)

SimpleIO.prompt("\n --- Your option: ");
String option = SimpleIO.readLine();

I do not have "jpb" library so I can't test it fully, but bottom line is you are calling class "Pet" all over place but you are missing this class(looks more like a bean). I asume you downloaded this code from sowhere or you typed from book/website and just didn't check for this class. So you have to get "Pet.java" from sowhere otherwise all the calls for Pet will do nothing and triger compiler for errors
PS: you should rename "Main.java" to something more approperiate like "PetTest.java"
I don't have Pet.java but I have Pet.class will that help.
Class is compiled version of java file ready to be used. Problem with this is you can't check if you have all methods there. So where did you get Pet.class then?

Yeah, that will solve the problem if it's the correct .class file.
Put this .class file in the directory where you have Main.java and compile again. (idea is to put Pet.class file in a directory that's part of CLASSPATH env var).
