Question

The description below explains the Strategy Pattern: In Strategy pattern, a class behavior or its algorithm can be changed at run time. This type of design pattern falls under the set of behavior patterns. Its Intent is: • Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from the clients that use it. • Capture the abstraction in an interface, bury implementation details in derived classes You have the following operations: • add : a + b • subtract : a − b • divide : a / b , assume a and b are NEVER 0. • multiply : a ∗ b; • power : a b , a raise to the power of b. Ex. 24 = 16. We will make the following assumptions: 1 ALL operands are ints. 2 ALL return values are ints. 3 Classes do not need any data-fields 4 Classes do not need any Constructors Implement a set of classes and an interface that adheres to the Strategy Pattern.
