Property readings for several classes, the best way

Question

Hi all
I have a program which in the development is going to handle different languages. Also there has to be several settings for the user. But here is the question:
The program has several different classes which all have specific constants. These should in time be customizable by the user when editing property-files. But how does one utilize the Property-class to it's best?
I have tried looking at [Best way property|http://forum.java.sun.com/thread.jspa?forumID=54&threadID=665253], but that didn't help me as i wanted.
I then passed on to Singleton and found interesting notes. Which I am thinking very deeply into using.
As i am not a very skilled programmer I have no idea as to how many constants you can have in one class, before it get's to "crowded".
I am guessing about 200 properties. Is that to many things to be handled in a class that is open during the whole thread of the program? In memory-consumption?
Thanks alot....

Ok so if i have this:
public class ClassOne {
    private JCheckBox user;
    public ClassOne() {... initializing all}
    public void setUser(boolean userChecked) {
        this();
        user.setValue(userChecked); // can't remember if this is the right code but... :)
}and the other
public class ClassTwo {
    private JCheckBox god;
    public ClassTwo() {... initializing all}
    public void setGod(boolean godChecked) {
        this();
        god.setValue(godChecked); // can't remember if this is the right code but... :)
}And then every time i need ClassOne i do like this:
ClassOne cOne = Factory.instanceOfClassOne();
ClassTwo cTwo = Factory.instanceOfClassTwo();Where the Factory is something like:
public class Factory {
//porperty readings up here.. no problem :)
    public ClassOne instanceOfClassOne() {
        ClassOne cO= new ClassOne ();
        cO.setUser(USER_PROPERTY_READING);
        return cO;
    public ClassTwo instanceOfClassTwo() {ClassTwo cT = new ClassTwo ();
        cT.setGod(GOD_PROPERTY_READING);
        return cT;
}Is this the way?
