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

Sometimes it is necessary to disambiguate:

public void setFoo(Bar foo) {
    this.foo = foo;
}

At other times, it's just a stylistic thing. On the whole, I try to avoid this.blah wherever possible as it is more verbose. In case you're wondering, the resultant bytecode is exactly the same.
