Please solve exercise 2. question 1 is to be added to the ClassA file. Question 2 Is to be added to the DataTypes file
pu File: Exercise 2 - Comparing Content of Objects 1. Add a public method equals(ClassA otherClass) to class class that returns the value true if this object and otherClass have the same value in variable numitems and (H) both arritems arrays are null or both store the same values and in the same order in the (default package 6 70 > ClassA.java 8 > D DataTypes.ja 9 > TestDataType 10 > TestEquals je 11 12 13 14 15 316 17 18 19 pul Arr LAB 2 CS1027 Computer Science Fundamentals II first numitems entries the method returns the value false otherwise. Do not try to access values from variable arritems if arritems is null 2. Add a public method equals(DataTypes other type) to class DataTypes that returns the value true) al primitive instance variables in this object and other Type have the same values and ) viables var in this object and otherType are equal according to method equals of class Class 2. Run the java class TestEquals, Fox your code if it fails any of the 4 tests.
