can you explain how to do this hw question

3. (10 pts) Given the following Java code class C public int foo (C p) t return 1; h class D extends CI public int foo(C p) t return 2; h public int foo (D p) return 3; h cp=new C(); Ca=new D(); D rnew DO int i = p. foo (r); int j- q. foo (q) int k = q. foo (r); Remember that in Java every object is accessed through a pointer and that methods are virtual by default.) Which methods get called in the three calls, i.e., what are the values of i, j, and k? Explain how the method selection works to result in these values
