In Java, why do people prepend fields with `this`?

Question

When referencing class variables, why do people prepend it with this? I\'m not talking about the case when this is used to disambiguate from method

Answer 1

The code is simplier reading. Another good practice, in my opinion, is calling the getXXX() in toString() too (instead then this.XXX), beacuse the getXXX() can have an important logic.

I think that use the name of attribute without this is'nt a good idea for the maintenance of the application.
