foreach - Java - can't change int value inside for-each loop -
this question looks hilariously obvious, can't see fault... i'm declaring int variable inside for-each loop , looks can't modify it.
for(string tmp : list) { int = 0; system.out.println("i = " + i); i++; }
list linkedlist not empty , exists somewhere in code. output is:
i = 0 = 0 = 0
is possible modify value of int inside such loop? thanks.
with each loop, create new i
variable, 1 unrelated previous ones previous iterations of loop. solution: declare above loop.
int = 0; for(string tmp : list) { system.out.println("i = " + i); i++; }
