Do not use this. keyword unless you have extremely good reason to do so.

It adds unnecessary noise to the code and the only reason why you probably need to use it in your classes is that you use the same names for private fields and for parameters.

To solve this, prefix private parameter names with underscore. Thanks to this:

• You can remove this. keyword
• You can easily figure out whether the field is private or not just by looking at its name (Underscore prefix = private)
