Question
## Part 2: Coding ### Task Write a complete Java program named `FindAverage` that contains the following: 1. **Main Method Requirements:** - **User Input:** - Ask the user to provide the number of rows and columns for a 2-dimensional array of integers. - **Array Creation:** - A main method must call the `getArray()` method to create the 2D array of the specified size. - Populate the array with random values from 0 to 100. - **Print Array:** - Print the elements of the 2D array created by `getArray()`. - **Compute and Print Average:** - Call the `printAverage` method that will: - Receive the 2-dimensional array as input. - Calculate the average of elements in this array. - Display the average on the console. 2. **Output Requirements:** - The average of all elements should be formatted as `xxx.xx`. 3. **Additional Guidance:** - **Hint:** You can print the 2D array at any point in the program using either a traditional for loop, foreach loop, or available methods in the `java.util` package. - **Program Comments:** - Add comments to your program. Start your program with the following header: ```java /****************************************** ``` Ensure that the program is well-commented and follows standard coding practices for clarity and maintainability.

Expert Solution
Step 1

logic to generate random number in range:- 

Min + (int)(Math.random() * ((Max - Min) + 1));

where set Min =1 and Max=100 (requirement)

 

Logic to get length of 2D array. 

randArray.length to get number of rows

 and randArray[i].length to get number of columns. 

 

 

end.
