Variable hiding
class A {
static int n=5;
static void go(){
int n=15;
System.out.println(n);
for (n=0; n<1; n++) {
System.out.println(n);
}
}
public static void main(String[] args) {
System.out.println(n);
go();
System.out.println(n);
}
}
Here the first declared n
is a class variable. The second n
in method go()
is a stack variable. Inside of method go()
it hides a class variable. Therefore the result will be as follows.
5
15
0
5
First println
, inside of main
method prints a class variable's value. The second println
(inside go()
method) prints a stack variable because stack variable here hides a class variable. The third println
prints the same stack variable's modified value. The last println
shows us that class variable remains the same after go()
method.
