Maybe you should ask the people who tell you to use it.
Speaking for myself (and not for those people whose opinions
I don't know), I use `this' explicitly:
- In constructors, to invoke a different constructor version,
- In constructors, to set an instance field from a parameter
of the same name,
- In equals() methods, where I like to compare instance fields
of `this' object and `that' object,
- When the phase of the moon is favorable.
Perhaps your associates feel that an explicit `this' is a good way
to distinguish element uses from variable or parameter uses? I
don't know; ask them.
