How can I retrieve a for-loop variable outside the loop?

Question

Hello together,
I've got a simple for loop like this:
for(int a=0;value;a++){
}
And now I want to select the int a outside the loop like that:
System.out.println(a);
What do I have to change in my code that it works?

Answer 1

Declare 'a' before using it in the for loop.
int a;
for(a = 0; value; a++) {
...
}
System.out.println(a)

Answer 2

OK, that works; thx
