Stock Price Simulator Solution

You are required to write a stock price simulator, which simulates a price change of a stock.

When the program runs, it should do the following:

 

·         Create a Stock class which must include fields: name, symbol, currentPrice, nextPrice, priceChange, and priceChangePercentage.

 

·         The Stock class must have two constructor: a no-argument constructor and a constructor with four parameters that correspond to the four fields.

o  For the no-argument constructor, set the default value for each field such as:

§    Name: Microsoft

 

§    Symbol: MSFT

 

§    currentPrice: 46.87

 

§    nextPrice: 46.87

o   For the argument constructor, set the value of four fields based on the arguments.

 

·         The Stock class must have accessors and mutators for all of its fields.

 

·         The setter methods must protect a user from setting the currentPrice/nextPrice into negative number. You can set the values to 0 if a user tries to change them to negative values.

 

·         The Stock class should have a SimulatePrice() method, which increases or decreases the currentPrice by 0 - 10% randomly.

 

·         The main program will ask user to enter a name, symbol, current price of a stock. Then, it simulates the prices for next 30 days. It displays the prices for the next 30 days on the console. If a user enters “NONE”, “NA”, 0.0 for name, symbol, current price respectively, then the no-argument constructor is used.

 

Note: your program must be user-friendly and intuitive. This is a part of your grade. In other words, even if your program does everything the problem statement states, your grade may be reduced because of difficulty to it.

Input

 

This program requires that you read in the following data values:

Ø   A stock’s name, symbol, and current price.

o   E.g., Microsoft Corporation, MSFT, 45.87.

 

You will use interactive I/O in this program. All of the input must be validated if it is needed. You can assume that for a numeric input value, the grader will enter a numeric value in the testing cases.

 

Output

 

Your program should display the stock’s name, symbol, current price, next price priceChange priceChangePercentage for each day.

 

Test case output: (green texts are user input)

 

Please enter the name of the stock: Microsoft

 

Please enter the symbol of the stock: MSFT

Please enter yesterday's price of Microsoft: 45.65

What File To Turn In and How to Turn In Your Work using Blackboard

 

You must turn in your Java program source files in a zip file. The zip file must include a Stock.java file which defines the Stock class, and a StockPriceSimulator.java file which includes the main() method. The zip file’s name must follow this format: hw6_StockPriceSimulator.zip
