Question

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.

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

Answer 1

class CompareArrays {
   public static boolean compare(int[] arrayOne, int[] arrayTwo) {
       // checking if lengths are different than it is false
       if (arrayOne.length != arrayTwo.length)
           return false;
       // iterating 2 arrays
       // comparing each element
       for (int i = 0; i < arrayOne.length; i++)
           if (arrayOne[i] != arrayTwo[i])
               return false;
       return true;
   }
}

public class CompareArraysTest {
   public static void main(String[] args) {
       // creating 4 arrays
       int arr1[] = { 1, 2, 3 };
       int arr2[] = { 1, 2, 3 };
       int arr3[] = { 1, 5, 6 };
       int arr4[] = { 11, 15, 16 };
       // comparing 1 and 2
       System.out.println(CompareArrays.compare(arr1, arr2));
       // comparing 3 and 4
       System.out.println(CompareArrays.compare(arr3, arr4));

   }
}
