More on Strings, Classes and UML
Part 1: The Stock class (edu.albany.hw2.stock)
Design a class named Stock that contains the following:
1. A Symbol enum field named symbol for the stock’s symbol
2. A double data field name previousClosingPrice that stores the stock price for the previous day
3. A double data field named currentPrice that stores the stock price for the current time
4. A constructor that creates a stock with specified symbol and name
5. The accessor functions for all data fields
6. The mutator functions for previousClosingPrice and currentPrice
7. A function named getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice
8. The Enum “Symbol” – will be used to denote stock for companies
a. Declare the stock symbols for the following: Microsoft, Apple, Google, Amazon, AT&T
b. The symbol should have a string value which is the company name
c. Example Symbol.MSFT represents Microsoft stock.
Draw the UML diagram(s). Implement the classes. Write a test program that creates a Stock object with the stock symbol MSFT and the previous closing stock price of 58.9. Set a new current price to 59 and display the price change percentage. Repeat for one other company.
Part 2: Morse code generator (edu.albany.hw2.morse)
Morse code is a code where each letter of the English alphabet, each digit, and various punctuation characters are represented by a series of dots and dashes. Figure 1 shows part of the code. Write a program that asks the user to enter a string and then converts that string into Morse code. Use hyphens for dashes and periods for dots.
Some points to consider:
1. Design: Figure out what classes and methods you need to develop. Ex. Utility classes, class to represent Morse code generator, etc
2. Architecture: Create a UML of your architecture idea. Make it re-usable and configurable by someone other than yourself
3. The input can be given in two ways
a. Command line args
b. Passed into a function
4. Use string buffers when you are (or are going to) manipulating large Strings
5. Use appropriate accessors for your variables and methods
6. EXPLAIN: What strategy you used to store the morse code encoding table and WHY? (-10 points if this is missing). Can add it as comment on the class.
Part 3: Car Instrument Simulator (edu.albany.hw2.car)
For this part, you will design a set of classes that work together to simulate a car’s fuel gauge and odometer. The classes you will design are the following:
