"
Develop a Java program for the HighSum game Administration module.
Administration Module
This module allows the administor to
1. Create a player
2. Delete a player
3. View all players
4. Issue more chips to a player
5. Reset player’s password
6. Change administrator’s password
7. Logout
This module will have access to two files (admin.txt and players.bin)
The first text file (admin.txt) contains the administrator hashed password (SHA-256).
For example
0b14d501a594442a01c6859541bcb3e8164d183d32937b851835442f69d5c94e
The second text file (players.bin) contains the following players object information in a binary
serialized file.
• Login Name
• Password in SHA-256
• Chips
Login Name Password in SHA-256 Chips

Game play module
Modify Assignment 1 HighSum Game module such that the Player data is read from the binary file
players.bin. And different players are able to login to the GameModule.
You have to provide screen outputs to show the correct execution of your program according
to the requirements stated.
The required test runs are:
• Admin login
• Create a player
• Delete a player
• View all players
• Issue more chips to a player
• Reset player’s password
• Change administrator’s password
• Administrator login and logout to admin module using updated password.
• Player login and logout to game module using updated password."
