Analyze the following code: public class Test{ public static void main(String[] args) { B b = new B(); b.m(5): } } class A { int i; } } public void m(int i) { this.i = i; System.out.println("i is " + b.i); class B extends A { public void m(String s) { } } The program has a compile error, because m is overridden with a different signature in B. The program has a compile error, because b.m(5) cannot be invoked since th method m(int) is hidden 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.

Question
Answer this question regarding java:
![Analyze the following code:
public class Test{
public static void main(String[] args) {
B b = new B();
b.m(5);
}
}
class A {
int i;
System.out.println("i is " + b.i);
}
}
public void m(int i) {
this.i = i;
class B extends A {
public void m(String s) {
}
}
The program has a compile error, because m is overridden with a different
signature in B.
The program has a compile error, because b.m(5) cannot be invoked since the
method m(int) is hidden 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4657391b-9410-4056-b18b-8112fb5f83eb%2F3246b1e8-9c98-4eaf-8ea6-ff5c135d2c89%2F1vmc1do_processed.jpeg&w=3840&q=75)

The program has a compile error, because m is overridden with a different
signature in B.
The program has a compile error, because b.m(5) cannot be invoked since the
method m(int) is hidden 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
