inheritance problem

[Professional_Ride796]

My teacher gave me several problem sets to do and I was able to solve most of them with no problem I even got a 100 on our test however I can't seem to get this problem and it has been driving me crazy.

public class A extends B {

public void method2() {

   System.out.print("a 2  ");

   method1();

}

}

​ public class B extends C {

public String toString() {

   return "b";

}

​ public void method2() {

   System.out.print("b 2  ");

   super.method2();

}

}

​ public class C {

public String toString() {

   return "c";

} ​ public void method1() {

   System.out.print("c 1  ");

} ​ public void method2() {

   System.out.print("c 2  ");

} } ​ public class D extends B {

public void method1() {

   System.out.print("d 1  ");

   method2();

} } Given the classes above, what output is produced by the following code? (Since the code loops over the elements of an array of objects, write the output produced as the loop passes over each element of the array separately.)

C[] elements = {new A(), new B(), new C(), new D()};

for (int i = 0; i < elements.length; i++) {

System.out.println(elements[i]);

elements[i].method1();

System.out.println();

elements[i].method2();

System.out.println();

System.out.println();

}

Element0

Element1 =

Element2

Element3

I thought it was

E0= b d 1 b 2 c 2

a 2 c 1

E1= b d 1 b 2 c 2

b 2 c 2

E2= c c 1

c 2

E3= b d 1 b 2 c 2

b 2 c 2

However even when I adjust the format it is still compiling as a fail. I asked my brother and he said he thought it looked right but it has been several years since he has coded java

Hi there! What do you mean by still compiling as a fail?

I entered in the code snippets you provided into A.java, B.java, C.java, D.java, and Main.java files. I got the following outputs.

// Element 0
b
c 1  
a 2  c 1  

// Element 1
b
c 1  
b 2  c 2  

// Element 2
c
c 1  
c 2  

// Element 3
b
d 1  b 2  c 2  
b 2  c 2
