Analyze the following code:

public class Test {

public static void main(String[] args) {

Z z = new Z(); z.m(10); System.out.println(\"i is \" + z.i);

} }

-------------ANOTHER FILE------------------------- public class A {

int i;

public void m(int i) { this.i = i;

} }

-------------ANOTHER FILE------------------------- public class Z extends A {

public void m(String s) {

} }

1. The program has a compile error, because m is overridden with a different signature in Z.
2. The program has a compile error, because z.m(10) cannot be invoked since the method m(int) is hidden in Z.
3. The program has a runtime error on z.i, because i is not accessible from z.
4. The method m is not overridden in Z. Z inherits the method m from A and

defines an overloaded method m in Z.
