Given: interface Fish { } class Perch implements Fish { } class Walleye extends Perch { } class Bluegill { } public class Fisherman { public static void main(String[] args) { Fish f = new Walleye(); Walleye w = new Walleye(); Bluegill b = new Bluegill(); if(f instanceof Perch) System.out.print("f-p "); if(w instanceof Fish) System.out.print("w-f "); if(b instanceof Fish) System.out.print("b-f "); } } What is the result?
