[Bluej-discuss] How to call an accessor method in a different class?

[Lon Levy]

Hi Barry,

I asked Michael Kolling to consider using this. with all instance references a few years ago.  He told me that it was an interesting idea, but that it was nonstandard enough that he was not going to include it in future versions of Objects First (which I think is otherwise a fine text).  Please consider making the request.  Maybe if enough of us relate the concept to him and to David Barnes, they will reconsider.

Regards,

Lon.

I think this is a great idea from a pedagogical standpoint. My BlueJ  
students seem to understand variable and parameter names. When the  
book introduces "this" in a constructor, it really throws the students  
for a loop. Up until that point, they have this idea that Java names  
are "global" and should be distinct within a class. Seeing a field and  
a parameter with the same name really gives them trouble and they have  
difficulty getting their heads around it.

I'm going to try using the "this" technique this coming semester.  
Problem is, the BlueJ book doesn't consistently use it. Can we get the  
authors to apply this principle?
