Simple application server in Java

My first Java implementation of a Server (it was 2016). It features:

1. A HTTP server
2. A chat server (with web sockets)

javac -sourcepath src -d out Application.java
java -classpath out Application [-chat] [-http] [chat port] [http port]

• -chat disables the chat server
• -http disables the HTTP server
• chat port runs the chat server on the given port (default: 12345)
• http port runs the HTTP server on the given port (default: 9000)

To connect to the chat server with a client, you can use telnet or nc:

nc 127.0.0.1 12345

You will be prompted to chose between:

• ECHO_SERVER: echoes the messages you send
• REVERSE_SERVER: reverse the messages you send
• BROADCAST_SERVER: forwards the messages you send to all the connected sockets
