ok, I DID IT! I am a little stoked. here is what I did:
very cool. thanks to everyone for pointing me in the right direction.
Hi Jeff, Thanks for the info. Thats what I want to do. The employeeID
is pulled from form one. the property is in form2, and form1 pushes
the value to the property in form2 (again C#):
Form2 frm = new Form2() // create a new instance of form2
frm.employeeID = this.txtEmployeeID.Text; // set form2's employeeID
property
frm.ShowDialog(); // open the form
the syntax above is what I am looking for, and the data is loaded in
form1. Based on what I have read here, I am thinking my code would
look like so, a combination of a property and a method:
private String _employeeID;
public void setEmployeeID(String employeeID)
{
_employeeID = employeeID;
}
I am not sure I would need a get statement as the private variable
_employeeID would only be used within the
current class. Then again, if wanted to access the employeeID from
outside the class, would I add the following?:
public int getEmployeeID()
{
return _employeeID ;
}
Does this sound right? I realize this is pretty basic, but I think if
I understand this I would have a pretty good grasp. I guess I could
try it.
Thanks again.

OK, I am back. I completely under the getter/setter concept. However,
what I am trying to do is create a property that can be used to pass
values between forms (JFrames).
If I had two JFrames, one being say, employee basic information
(Form1), and the other containing extended info about the same employee
(Form2). When I open Form1 to an employee record, then, in Visual
Studio for example, I would then create a property in Form2 like so:
private string _employeeID;
public int employeeID
{
get { return _employeeID; }
set { _employeeID= value; }
}
In Form1 I set the Form2 property when the form instance is created as
follows:
Form2 frm = new Form2();
frm.employeeID = xxxxx
Finally, in Form2, I can use the _employeeID value to populate the form
with data.
Most of my apps I do are based off of a database design or concept, and
a significant part of the model for my applications start there (at the
database). Anyone know of any good tutorials or books regarding
database-cebtric application design using Java?
Thanks again.

I am new to java (currently using C#). I am trying to learn java and I
am having a little difficulty in creating and using a property. Here
is a sample from C#:
private int _myValue;
public int myValue
{
get { return _myValue; }
set { _myValue = value; }
}
how would I do this in java? Any help is appreciated.
Presuming you are selecting the employee in Form1, you can expose a
method in Form2 that is called by Form1 when the employee ID is
changed. That method would then change the displayed data on Form2 to
keep the info in sync. So, rather than have Form2 pull the info from
Form1 as a property, you push the info from Form1 to Form2 through an
exposed method.
I like MYSQL and Java Developer's Guide by Mark Mathews, et al, but I
use MySQL for most of my database work.
