Implement the following in my java program which is written under the requirements:
When a new member joins, the server will check if it is the first member. If it is, the member will be informed and become the coordinator. If not, the member will request details of existing members from the server and receive everyone's IDs, IP addresses, and ports, including the current group coordinator.
The new member will then contact everyone through the server to let them know that they can update their set of members to include the new member.
If some members do not respond, the new member will inform the server, and the server will inform other members to update their local list of existing members.
If the coordinator does not respond, any new member will become the coordinator. The coordinator will maintain the state of group members by checking periodically how many of them are not responding and inform active members about it so they can update their state of members.
Implement a messaging system for members to send private or broadcast messages to every other member through the server.
Print out messages sent to and by the members.
Allow the program to run either automatically or manually. In the former case, simulate the task automatically without accepting any input parameters from users. In the latter case, the program will require user input to simulate the task.

1. Implement the following in my java program which is written under the requirements:
When a new member joins, the server will check if it is the first member. If it is, the member will
be informed and become the coordinator. If not, the member will request details of existing
members from the server and receive everyone's IDs, IP addresses, and ports, including the
current group coordinator.
The new member will then contact everyone through the server to let them know that they can
update their set of members to include the new member.
If some members do not respond, the new member will inform the server, and the server will
inform other members to update their local list of existing members.
If the coordinator does not respond, any new member will become the coordinator. The
coordinator will maintain the state of group members by checking periodically how many of
them are not responding and inform active members about it so they can update their state of
members.
Implement a messaging system for members to send private or broadcast messages to every other
member through the server.
Print out messages sent to and by the members.
Allow the program to run either automatically or manually. In the former case, simulate the task
automatically without accepting any input parameters from users. In the latter case, the program
