Vectors? Why does this not work?

2002-01-10 Thread Rick Roberts 

Why does this simple example not work?
I am using Tomcat 3.3 and JDK 1.3.1_01 and Redhat Linux 7.2

Thanks,

First, you should take this question to another forum since this one
is about the Tomcat Servlet Container.

Second, you probably need to do some basic Java learning since this.

Third, you are using static variables to hold your names.

Re: Vectors? Why does this not work?

2002-01-10 Thread Matt Egyhazy 

it looks like your code is working just fine to me, its doing exactly what
you wrote it to do.  i suggest reading an introductory java book, the wrox
java2 book is ok.  and this is not the mailing list for these types of
questions.

Re: Vectors? Why does this not work?

2002-01-10 Thread Ed Sesek 

Rick,

You are declaring the fields last_name, first_name, and middle_name as
static so there is only one instance of each of those for your SimpleClass (no
matter how many objects of type SimpleClass you create).

Re: Vectors? Why does this not work?

2002-01-10 Thread Rick Roberts 

 First, you should take this question to another forum since this one 
is about the Tomcat Servlet Container.

I'm actually building a bean for a Tomcat JSP app that I am working on. 
 I presented the code this way to simplify my description of the problem.

 Second, you probably need to do some basic Java learning since this.

I feel like an idiot.

 Third, you are using static variables to hold your names.

That is it
I looked at this for hours and never noticed static.

Basically:

1. I'm an idiot.
2. And you quickly pointed that out.
3. I'm grateful.

Thanks,
Rick

Must be a trick school assignment.  The member variables are static.

Take the static out of the first name only and you will get something 
like this.  Easy.  lol.
