Lab 9 - Generics: Extends

Objectives

• Restrict the set of types that can be used in instantiation

Resources

• Writing Generic Classes and Methods
• Generics in the Java Programming Language
• Lesson: Generics
• Java tutorial: Introduction to Java Generics

Assessment:

• Downlaod Code MyWildcardEx.java

• We have two classes called CompAEmp and CompBEmp extended Emp class, and we have a generic class called MyEmployeeUtil, where we have utilities to perform employee functions irrespective of which company emp belongs to. This class accepts subclasses of Emp. In case if we want to compare salaries of two employees, how can we do by using MyEmployeeUtil class?

• Your Objective is to design Generic class MyEmployeeUtil such that its function isSalaryEqual can compare either objects of the subclass of Emp class.
