Module $8$: Multi$-$Dimensional Arrays

Assignment $8$: SumDifference

This assignment is to teach the creation and processing of $2-$dimensional int arrays.

Assume that "intar" is a $2-$dimensional int array $($made out of rows and columns as in pages $289-321),$ which contains the following int values:

$101326346090$

$254657887791$

$293041528292$

Write a java program that you will call Assign$8.$java that has a main method and declares:

The above two$-$dimensional array intar properly as is$.(5$ points$)($Remember this needs to be declared once$).$

A method printArrayAsIs$()$ which has no parameter and returns nothing and is implemented as follows:

public static void printArrayAsIs$()\{\}$

Use a nested for loop $($two consecutive for loops$)$ to print the $2$ dimensional array intar declared above in the exact following order $($use the nested for loop in page $291$ as an example$)(10$ points$)$:

$101326346090254657887791293041528292$

printArrayAsIs$()$ is called from main$().(10$ points$)$

A method printArrayColumnWise$()$ which has not parameter and returns nothing and is implemented as follows:

public static void printArrayColumnWise$()\{\}$

uses a nested for loop$($ two consecutive for loops$)$ to print the $2$ dimensional array intar declared above in the exact following order $($use the nested for loop in page $291$ as an example$)(25$ points$)$:

$102529134630265741348852607782909192$

That is: to print the values of intar going across the columns instead of across the rows.

printArrayColumnWise$()$ is called from the main$()$ method. $(10$ points$)$

A method sumDifference$()$ which has no parameter and returns nothing and is implemented as follows:

public static void sumDifference$()\{\}$

uses a nested for loop$($ two consecutive for loops$)$ to print the sum of the elements of intar declared above in the exact following order $($use the nested for loop in page $291$ as an example$)(30$ points$)$:

$10-13+26-34+60-90+25-46+57-88+77-91+29-30+41-52+82-92$

That is: to print the final result of the sum of elements as calculated above $=-129$

sumDifference$()$ is called from the main$()$ method. $(10$ points$)$

Do not forget to compile and run Assign$8$ to verify that the class is running. Drop the Assign$8.$java in the drop box.
