Changing a dynamic variable to static while runtime

Question

How can I change a variable to be static runtime?
I have a defined variable but I can't put data into it after a few calculations, but when I have put data into it I want to make sure that the data doesn't get overwritten. Is this possible?

Answer 1

Kinda, but not quite what I meant. I'll try to give a
rough code example:
public class Foo {
int notToBeChanged;
public Foo (int Bar) {
notToBeChanged = bar * bar;
// From here on it shall not be possible to change
ge what's in notToBeChanged
public void Bar () {
notToBeChanged = 5 // Illegal!!
Of course this is easily overcome by just being
careful about how I code this. But what I'm worried
about is that when someone else will come to do
maintenance on my code that they won't be so careful.
Heck, they won't even know that I don't want that
variable changed.You can't change a variable to be static. Given what you've said, I don't think that is what you want. You can make a class immutable by not providing any capability to change the variables (no mutator methods).
As far as protecting your code from other programmers who inherit it when they get the responsibility to maintain it ... you can't. Document your intent, and hope they are intelligent enough to read and understand.
