Analyze the following code:

public class Test {
public static void main(String[] args) {

B b = new B();

b.m(5);

System.out.println("i is " + b.i);

}
}

class A {
int i;

public void m(int i) {

this.i = i;

}
}

class B extends A {
public void m(String s) {
}
}

◦ The program has a compilation error, because b.m(5) cannot be invoked since the method m(int) is hidden in B.
◦ The program has a compilation error, because m is overridden with a different signature in B.
◦ The program has a runtime error on b.i, because i is not accessible from b.
◦ The method m is not overridden in b. B inherits the method m from A and defines an overloaded method m in b.
