Private variable with toString ()

First compilation error:

System.out.println ("Type: " + type + "\t" + "Make: " + make);

Product doesn’t have the make instance variable. Its subclass GolfHat declares the variable . Subclass inherits non-private members of a superclass, it doesn’t work the other way round.

Logical error :

if (type=="Glove"){


This is an erroneous way of comparing String contents . Use equals() method instead.

if ("Glove".equals(type)){
