Hartmut,

there are situations where a this matters, e.g. if you have an
instance variable and a local variable or parameter with the 
same name:

..
private String name;
..
public void setName(String name) {
  this.name = name;
}

Of cause I'd recommend to choose a distinct parameter name like 
"newName"... ;-)

Prefixing an instance method call with "this." is always 
redundant, but sometimes "more clear". It's a question of taste.
