Properties file(s)

[John Warkentin]

I am writing a simulation that will use a set of variables which I plan to
store externally from the code. Default values for the variables will be
stored in a properties file (File 1). For example:

File 1:
X=3
Y=7
Z=2

File 2:
Y=5

After opening and reading File 1, how could I open a SECOND properties file
(File 2) and read values to override the values read from File 1? I want
the end result to be:

X=3
Y=5
Z=2

John,

Just use the load() method of the Properties class. Load twice - one for
each file.

John,
In addition to what Kent said, you will want to separate the persistance
from the domain object. So while your data is store in properties files,
you should hide that. To do this, determine what x,y,z are or are part of.
A guess, from the info you provided, is that it is Point object.
