android - Builders - creates a new instance each time? -

i'm using couple of builders make bunch of objects. i'm doing this:

list<productofbuilder> list; builder b = new builder();  for(some iterable in i) {     b.setsomeparam(i);     list.add(b.build()); } 

is okay do? in other words, builder create new instance of productofbuilder each build()?

is okay do? in other words, builder create new instance of productofbuilder each

no not. accordingly code posted changing same reference. in end list contains n builder, content of last call setsomeparam.

it different if have collection of objects builder supposed build, , calling @ every iteration build().

list<typetobuild> list; typetobuild.bilder builder; (type t : parmas) {    builder.setparamns(t);    list.add(builder.build());  }
