refactor: Refactoring of the code base

[bharathkalyans]

• Codebase contains a lot of warnings and redundant code.
  Eg.The below code can have a private constructor, so an object can't be created.

public class Constants {
    public static final String AGENT_VERSION = "1.0.1";
}

@artpar I would love to work on this!!
Can you assign this to me?

@bharathkalyans Thanks for the PR.

Changes which rearrange the keywords and reformat the code are something which I don't want to accept at this point.

This leaves the 3 changes,

• Contants.java private constructor
• fixing of the comment in Unlogged.java
• ClassTypeUtil.java private constructor

They look fine and I can merge them if you can remove the formatting changes.
