Question

Details:

Create a class called CompareArrays that determines if two specified integer arrays are equal.

The class should have one static methods:

• public static boolean compare(int[] arrayOne, int[] arrayTwo) – Which compares the two arrays for equality. The two arrays are considered equal if they are the same size, and contain the same elements in the same order. If they are equal, the method should return true. Otherwise, the method should return false.

NOTE: You are not allowed to use the Arrays.equals method for this programming assignment.

Create a second class called CompareArraysTest that contains the main method, and thoroughly tests the ComparyArrays.compare method. This test class does not need to ask users for input. Just create the needed arrays to ensure that you test the ComparyArrays.compare method well. The thoroughness of your testing in will impact your grade.

Code in text format (See above images of code for indentation):

import java.util.*;

/*class definition*/

class CompareArrays

{

    /*static method to compare two arrays*/

    public static boolean compare(int[] arrayOne, int[] arrayTwo)

    {

        boolean check=true;

        /*if lengths are not equal then return false*/

        if(arrayOne.length!=arrayTwo.length)

            return false;

        else

        {

            /*check for same size and same order*/

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

            {

                /*if order is missed then return false and break*/

                if(arrayOne[i]!=arrayTwo[i])

                {

                    check=false;

                    break;

                }

            }

            /*return check*/

            return check;

        }

    }

}

/*class to test above method**/

public class CompareArraysTest

{

    /*main method*/

    public static void main(String[] args)

    {

        /*two arrays initialization*/

        int[] arrayOne={12,3,3,4,5};

        int[] arrayTwo={12,3,3,4,5};

        /*method call*/

        boolean check=CompareArrays.compare(arrayOne,arrayTwo);

        /*print equal or not equal*/

        if(check)

            System.out.print("Equal");

        else

            System.out.print("NotEqual");

    }

}
