Assignment 4 - Recursive Forum Posts Each message in an on-line forum is captured with a unique message ID, a parent ID, and the text of the message The parent ID is the message ID of another message to which a message is replying (see Figure1). The first message will have a parent ID of 0, indicating that it is not replying to any message (i.e., it is a new discussion) There could be more than one discussion in a forum! Loops, beginner Hello I am a beginner in Java and had a question regarding Loops, This message would have a parent ID of O the question in the book asks for The sum of all odd digits of n.

(1) Create an appropriate class or set of classes to encapsulate the messages (e.g., a Message class) (2) Create an application (i.e., a class with a main in it, right?) where the messages are read in from a file named msg.txt" and displayed in a nesting hierarchical structure that shows the relationship of the messages (i.e., each reply is displayed on a separate line, indented by 2 white spaces relative to the message being replied to) Remember to document your code using Javadoc comments
