The database of this HTTP/Rest server will be handled by a JSON file.

• Created a HTTP Server using java ServerSocket and Socket.
• Created a Client Handler where the requests will be parsed and later handled
• Created a Request Header class and Interface. Mostly for more readable code.
• Created Json Manager class.
• Created Parser class where messages will be parsed before custom objects before initialization.

• Request handler implementation for clients
• JSON Manager class implementation for handling the data in the database
• Operation responses implementation
• Exception handler

• Created types for Message, MethodCode, OptionCode, ResponseCode, TypeCode.
• Created Parser that takes in a Byte array and parses every byte into types and lastly create a Message.
• Created Interfaces for Parser.
• Create UDP Client that sends message for connection.

• Some classes are still missing Interface
• POST request left.
• Parser from Types to Messages left
• Need to check what is opaque type
• Need also to figure it out what happens when a option is 0 bytes long. How is the content format decided?

Labb one uses the CoAP standard (RFC 6690, RFC 7252, RFC 7959, RFC 7641)
