Was there any point to declaring x and making it equal to 1? I don't think so. 
Couldn't you have said:

For (int x = 0; ...

It's declared in a higher scope.

Take care,

Hi,
What makes x global?

Thanks.

That's what I was trying to point out that the global x had the focus so to 
speak. Yes, I was counting on my fingers and since I had
one bit off by a shark a few years back I live in base 9.

No, because there's no int specification in the for loop ... That x is the 
global x.

Also, it gets incremented to 10, not 9.

Hey now:

I've finally resolved the issue I was having with variables being reused 
multiple times in the same class...

For the sake of brevity:

Public class MyClass {

Private int x = 1;

Public MyClass() {
myMethod();
}

Private void myMethod() {
For (x =0; x<10; x++) {
}
}
}

...obviously x gets finally incremented to 9 and since it's global then it 
throws off any reuse of the variable.
