No, you are not wrong nor alone :-)

I'm doing a lot of Java these days and the "ideology" that I'm
following is to try to get *all* initialization in the constructor. If
there are many constructor parameters (especially with the same types,
when they are difficult to tell apart), then I use a builder object
that can construct my desired target one piece at a time and has
sensible defaults. Something like (made up example)
File f = new FileBuilder().withTitle("foo").withAccess("r").build();

best regards,
Vlad
