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 most often see people do this because it triggers the intellisense. I personally prefer to leave off the "this." because it creates more code without any value.

Answer 2

1. Defensive programming (in case someone editing the code later adds a parameter or local with a conflicting name
2. Make the code "self documenting," more obvious

Answer 3

They are perhaps a Python programmer and get tortured/lost/confused without an explicit this.

Answer 4

"this" prevents confusion with instance variables with the same name in the parent class/es.

It's pretty much the complement to prepending with "super".
