**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 | 23 | 45 | 6```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 | 45 | 6 | 7 | 89 | 10 | 11 | 1213 | 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** **Lab9B: Lab9A, but now with more math**For this exercise, you will be writing a program that will build upon the previous program. So please make a new class file, copy, and rename the code you have already written for Lab9A. **Please also remember to rename the file and (and in the case of Java and C# students) class name to Lab9B.**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 arrayPlease 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**.

Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.) You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below. Example Output: How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 If your code looks like the code below, it is not what I’m asking for. The code below is making a square multidimensional array, not a triangular one. The code below is just leaving certain spots empty so that it looks like a triangle. I will ask you…
