Need in java coding

create a client/server application that:

1. Calculates an average grade based on a set of assignment grades.
2. Determines the corresponding letter grade based on the average grade percentage. The client program and the server program should communicate over the network using messages.

The client program will collect assignment grades from the end user using the console. It will then send the grades to the server program, which will calculate the average grade percentage and determine the corresponding letter grade, both of which will be returned to the client program.

The programs should continue to run until the user indicates that they want to exit.

The following image illustrates the server program's console output:

The following image illustrates the client program's console output (with validation):
