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

A slight aside, but it may be worth noting that the "Clean Up" tool in Eclipse can be set to automatically add/remove this. to member accesses according to preference.

"Java / Code Style / Clean Up" in the preferences dialogue.
