Declaring variable in for loop

Question

if i declare a variable inside for loop. is a new variable created in each iteration?
for(int a=0; a<x;a++){
int y=3;
y++;
}

Edited
i am asking about java.

Answer 1

Yes. If you don't want this, you may nest the declaration of y into the initialization section of the for loop (some languages may not allow this), or simply outside the loop.

for (int a = 0, y = 3; a < x; a++, y++);

Answer 2

Declare it prior to the loop.

int y = 3;

for (int a=0; a<x; a++) y++;

Answer 3

but if i want to use y outside for loop. what is the solution?
