Batting Average Solution

Batting Average Solution

National Cricket Academy (NCA) wants to monitor the performance of the players registered with them based on the average runs scored in the matches played.

As a software consultant of NCA, help them by writing a java program to meet their requirements.

The application needs to store the runs scored by a player and calculate the average score.

Component Specification: Player Class

Requirement 1: Store the runs scored by a player

Whenever a match is over, NCA needs to store the runs scored by the players for future reference.

The addScoreDetails method accepts runScored as argument and adds it to the scoreList.

Component Specification: Player Class

Requirement 2: Calculate the average run scored

NCA Academy needs to monitor the performance of a player periodically based on the average runs scored.

The method getAverageRunScored should calculate the average runs scored based on the scoreList.

Component Specification: Player Class

The average runs scored needs to be calculated as:

Average runs scored = sum of all runs available in the scoreList / size of the scoreList

Create a Main class with the main method.

Design the menu as described in the Sample Input and Output as:

1. Add runs scored
2. Calculate average runs scored
3. Exit

Enter your choice

When the choice is 1, get the runs scored from the user and add it to the scoreList.

When the choice is 2, display the average runs scored.

The entire program should be executed within a loop. It should not terminate after the completion of a functionality. When the choice provided is 3, it should terminate with a message “Thank you for using the Application”.

Please do not use System.exit(0). Instead use break to terminate the program.

Sample Input / Output 1:
