For this exercise, please calculate two values from all of the numbers in the two dimensional array. The first value should be the sum of all numbers in the array. This should be stored in a separate "int" variable that is created outside the nested FOR loops. The second value should be the total average of all numbers in the Array. This should be stored in a separate “float" variable, also outside the nested FOR loop structure. So, in short: • Display the sum of the values in the array • Then display the average of the values in the array Please refer to the sample output below for visualization and match its style. As always: • Remember, the class name should be Lab9B. • The user input is indicated in bold. Sample Output #1: Please enter the number of rows: 3 Please enter the number of columns: 2 I have 3 rows and 2 columns. I need to fill-up 6 spaces. The 3x2 array: 1|21| 314|| 516| The sum of all the numbers in the 3x2 array: 21 The average of all the numbers in the 3x2 array: 3.5 Sample Output #2: Please enter the number of rows: 4 Please enter the number of columns: 4 I have 4 rows and 4 columns. I need to fill-up 16 spaces. The 4x4 array: 1|2|3|4|| 516|7|8| 9|10|11|12|| 13|14|15|16| The sum of all the numbers in the 4x4 array: 136 The average of all the numbers in the 4x4 array: 8.5

Transcribed Image Text:For this exercise, please calculate two values from all of the numbers in the two dimensional array. The first
value should be the sum of all numbers in the array. This should be stored in a separate "int" variable that is
created outside the nested FOR loops. The second value should be the total average of all numbers in the
Array. This should be stored in a separate "float" variable, also outside the nested FOR loop structure.
So, in short:
• Display the sum of the values in the array
• Then display the average of the values in the array
Please refer to the sample output below for visualization and match its style.
As always:
• Remember, the class name should be Lab9B.
The user input is indicated in bold.
Sample Output #1:
Please enter the number of rows: 3
Please enter the number of columns: 2
I have 3 rows and 2 columns. I need to fill-up 6 spaces.
The 3x2 array:
1|2|
314|
516|
The sum of all the numbers in the 3x2 array: 21
The average of all the numbers in the 3x2 array: 3.5
Sample Output #2:
Please enter the number of rows: 4
Please enter the number of columns: 4
I have 4 rows and 4 columns. I need to fill-up 16 spaces.
The 4x4 array:
1|2|3|4|
516|7|8|
9|10|11|12|
13|14|15|16|
The sum of all the numbers in the 4x4 array: 136
The average of all the numbers in the 4x4 array: 8.5
