- • UML diagram is useful to design a class.
- • It provides a standard graphical diagram for object oriented systems.
- • UML diagram was represented in a box that is divided into three portions. They are as follows:
- ○ The first portion is to write the name of the class.
- ○ The second portion is to list the data attributes of the class.
- ○ The last portion is to list the methods of the class.

Draw a level-0 diagram for this scenario: You are developing a new customer relationship management system for the BEC store, which rents out movies to customers. Customers will provide comments on new products, and request rental extensions and new products, each of which will be stored into the system and used by the manager for purchasing movies, extra copies, etc. Each month, one employee of BEC will select their favorite movie pick of that week, which will be stored in the system. The actual inventory information will be stored in the Entertainment Tracker system, and would be retrieved by this new system as and when necessary.

Write a complete Java program named FindSumAndAverage that performs the following tasks in 2-D array:
Main Method:
a. The main() method asks the user to provide the dimension n for a square matrix. A square matrix has an equal number of rows and columns.
b. The main() method receives the value of n and calls the matrixSetUp() method that creates a square matrix of size n and populates it randomly with integers between 1 and 9.
c. The main method then calls another method named printMatrix() to display the matrix in a matrix format.
d. The main method also calls a method named findSumAndAverage() which:
• Receives the generated matrix as input.
• Calculates the sum of all elements in the matrix.
• Calculates the average value of the elements in the matrix.
• Stores these values (sum and average) in a single-dimensional array and returns this array
• e. The main method prints the sum and average based on the result returned from findSumAndAverage()).
Enter the dimension n for the square…
