Java Refactoring - Replace Conditional with Polymorphism -


i made research refactoring college code. used jdeodorant plugin eclipse , throws me away, that:

if (object instanceof class1) {     do_something1(); } else if (object instanceof class2) {     do_something2(); } else if (object instanceof class3) {     do_something3(); }

should replaced polymorphism. fine, except methods do_something() refer operations not related object. me polymorphism not work.

is there other way avoid using instanceof , seems unprofessional.

thank much.
