+# Chat-Room-using-Java
+we will implement a network with socket programming using server- client architecture.
+We have a single server that can handle requests from two different types of clients Admin Client and Member Client.
+
+## Getting Started
+1. The server has two groups (i.e. two chat groups). The communication between clients in any group is handled by the server. 
+
+2. The server offers two services: SUBSCRIBE (for Member Clients only) and BROADCAST (for Admin Clients only). 
+
+3. A Member Client can subscribe to one of the two groups. If a Member Client subscribes to a group, then they will receive all messages sent in this group. However, they can not
+receive any messages sent in the other group. 
+
+4. A Member Client is NOT allowed to send any messages in the group. They just listen to the received announcements. 
+
+5. An Admin Client is the only client that can broadcast messages to a group. 
+
+6. If an Admin Client broadcasts a message to a group, then all the Member Clients in this
+group ONLY must receive this message. 
+
+7. An Admin Client does not subscribe to a group. They just broadcast their messages to one of the two groups. Therefore, if an Admin Client decides to broadcast a message to
+all Member Clients subscribed to a group, the admin will not receive the message himself. 
+
+8. The server must handle multiple requests from Member Clients at the same time. For example, the server can serve 3 Member Clients in Group 1 and 2 Member Clients in
+Group 2 at the same time. 
+
+9. The server must handle mutliple requests from Admin Clients at the same time. For example, the server can serve 2 Admin Clients broadcasting to Group 1 and one admin
+client broadcasting to Group 2. 
+
+10. If two admins are broadcasting to the same group at the same time, then the Member Clients of this group will receive the messages from both admins. However, the two
+admins will not see each others’ messages. 
+11. The server provides the service SUBSRIBE at port 3000, and provides the service BROADCAST at port 3001.
