Java Interface

Problem Statement A Java interface can only contain method signatures and fields. Interface can be used to achieve polymorphism. In this problem you will practice your knowledge on interfaces. You are given an interface   AdvancedArithmetic   which contains a method signature   public abstract int divisorSum(int n) . You need to write a class called MyCalculator which implements the interface. divisorSum   function just takes an integer as input and return the sum of all its divisors. For example divisors of 6 are 1,2,3 and 6, so   divisorSum   should return 12. Value of n will be at most 1000. Read the partially completed code in the editor and complete it. You just need to write the MyCalculator class only.   Your class shouldn't be public. Sample Input 6 Sample Output I implemented: AdvancedArithmetic 12 Explanation Divisors of 6 are 1,2,3 and 6. 1+2+3+6=12. import java.util.*; interface AdvancedArithmetic{   p...

Java Abstract Class

Problem Statement A Java abstract class is a class that can't be instantiated, that means you cannot create new instances of an abstract class. It works as a base for subclasses. You should learn about Java Inheritence before attempting this challenge. Following is an example of abstact class: abstract class Book {     String title;     abstract void setTitle(String s);     String getTitle()     {         return title;     } } If you try to create an instance of this class like the following line you will get an error: Book new_novel=new Book(); You have to create another class that extends the abstract class. Then you can create instance of the new class. Notice that   setTitle   method is abstract too and has no body. That means you must implement the body of the that method in the child class. In the editor we have provided ...

Calculate the number of elements of an array that are not divisors of each element.

Task description You are given a non-empty zero-indexed array A consisting of N integers. For each number A[i] such that 0 ≤ i < N, we want to count the number of elements of the array that are not the divisors of A[i]. We say that these elements are non-divisors. For example, consider integer N = 5 and array A such that: A[0] = 3 A[1] = 1 A[2] = 2 A[3] = 3 A[4] = 6 For the following elements: A[0] = 3, the non-divisors are: 2, 6, A[1] = 1, the non-divisors are: 3, 2, 3, 6, A[2] = 2, the non-divisors are: 3, 3, 6, A[3] = 3, the non-divisors are: 2, 6, A[6] = 6, there aren't any non-divisors. Write a function: class Solution { public int[] solution(int[] A); } that, given a non-empty zero-indexed array A consisting of N integers, returns a sequence of integers representing the amount of non-divisors. The sequence should be returned as: a structure Results (in C), or a vector of integers (in C++), or a record Results (in Pascal), or...
