This is NOT a triple but a triple pattern in SPARQL...triples do not
contain variables.

This is not an instance! Again, this is a triple pattern. An instance
would be team1.

> favVariable);*
This will list the subjects, e.g. team1 in your example, but given that
favVariable is a variable, this will not work. Your example is confusing
as you're mixing up SPARQL variable and Java variables. If favVariable
is some RDFNode, i.e. in your case an RDF resource that denotes a
particular stadium, then it will return all resources whose favorite
stadium is the stadium denoted by your Java variable favStadium.

Save it as data property? What does this mean? I would assume that a
stadium is an RDF resource, not a plain String literal.
And what do you mean by save to file? You can serialize the whole RDF
model to disk, or you could generate a model for team1 only and
serialize write it to disk, or you could write it as CSV to disk ,or ...
