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

I try to use 'this.whatever' when writing large chunks of code, because it was easier to figure out what was being referenced. When reading large chunks of code written by other people, at certain points I would often get confused as to whether they were referencing instance variables or local variables.
