There is a computer class with private String instance variables name and company. You should override the Object equals method to evaluate whether both computers have the same name and company, in which case they are "equal". There is also a Laptop class that inherits from computer while adding a String keyboardType instance variable. The Laptop class should override the equals method from computer, instead evaluating whether the name, company, and keyboardType are the same $($remember that name and company are not readable to Laptop so some polymorphism might be needed$).$ Fill in the code so that both equals$()$ methods work.
