Programming Assignment 02

Overview

We are building on the start made in PA01 to continue building the reporting system for our investment management company. In this assignment, you will build a basic framework for the securities management portion of the system.

Startup Materials

The following have been provided to you:

These instructions

UML Class Diagrams for:

o Security

o MutualFund

o Stock

o CostBasis (interface)

A test harness for use in testing your code: Test_SecurityHierarchy.java

Sample expected output results

Requirements

CostBasis - Create the CostBasis interface according to the requirements in the UML. The interface will be used in the classes of the Security hierarchy to calculate the cost basis for a given investment, according to the instructions provided in the individual class diagrams.

Security - Create the Security class according to the requirements in the UML Class Diagram. Note that the UML Class Diagram provided does not include required standard methods these should be included at all times as defaults. Naming for such methods MUST follow standard naming conventions. All classes in the Security hierarchy must implement the CostBasis interface.

MutualFund - Create the MutualFund class according to the requirements in the UML Class Diagram. Note that the UML Class Diagram provided does not include required standard methods these should be included at all times as defaults. Naming for such methods MUST follow standard naming conventions. The MutualFund class must provide concrete instructions for implementation of the CostBasis interface.

Stock - Create the Stock class according to the requirements in the UML Class Diagram. Note that the UML Class Diagram provided does not include required standard methods these should be included at all times as defaults. Naming for such methods MUST follow standard naming conventions. The Stock class must provide concrete instructions for implementation of the CostBasis interface.

Security (Abstract) Interface: CostBasis Attributes private custNumber: String private purchDt: int A unique identifier for a customer; must be 7 digits in length; must be greater than 10000 Purchase date of Security in Julian date format: yyyyddd. The value for year must be greater than 1900. The value for days must be between 1 and 365, inclusive Purchase price of Se Number of shares purchased; for display purposed, decimal positions should be limited to three (3) Market symbol of S private purchPrc: double private shares: double private symbol: String r share, in dollars Operations public Security nbr String, Full constructor date: int, price: double, qty: double sym: String ): public toString(): String Returns a formatted String object describing the Security object: The Security belongs to Customer# custNumber, shares shares of symbol were purchased on purchDt for SpurchPrc per share. NOTES: The interface method calcCost is not given a concrete definition here There can be no null constructor defined for this class
