nope ...


java passes primatives by value and objects
by reference copy ...

no it doesn't - it passes a copied object's reference.

otherwise code like this:

void a(Object obj){
  obj = null;
}

void b(){
  Object o = new Object();
  a(o);
  if(null == a){
   System.out.println("not possible");
  }
}

would print "not possible". - it wont.
