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.

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++);

Declare it prior to the loop.
int y = 3;
for (int a=0; a<x; a++) y++;
+ 3
but if i want to use y outside for loop. what is the solution?
