why there is an error

Question

static int removeElement(int[] nums, int val) {
String c = "-122";
int b = 9;
for (int b = 0;b<122;b++){}
}

question: why the int b in for block can not coexist with int b in method removeElement
why int b in for block can not shadow the int b of the method body.

Answer 1

Hi! you declare the variable b twice. you can't do that. and why do you need a c variable with a string value inside?
