stocky (manage stocks)

Introduction:

In the development of our Stocky, we leveraged the power of classes, switch statements, and error handling with try-catch-finally to create a robust and user-friendly tool for managing stock portfolios. This write-up aims to provide a detailed explanation of how these programming concepts were utilized to build key features within our application.

I. Classes for Stocks and Portfolios:

Stock Class: Our application revolves around the concept of stocks. To model individual stocks effectively, we created a Stock class. This class encapsulates the attributes and behavior associated with each stock. Here's how we implemented it:

  • Properties: The Stock class includes properties such as symbol, numShares, purchasePrice, and currentPrice to represent the essential characteristics of a stock.

  • Methods: We added methods to calculate the current value of a stock (calculateValue()) and update its current price (updatePrice(newPrice)). These methods enable users to track the real-time value of their holdings.

Portfolio Class: To organize and manage multiple stocks, we developed a Portfolio class:

  • Properties: The Portfolio class holds properties like name, owner, and an array of Stock objects (stocks) to maintain information about each portfolio's name, owner, and constituent stocks.

  • Methods: We implemented methods to add and remove stocks from a portfolio (addStock(stock), removeStock(stockSymbol)), calculate the total value of a portfolio (calculateTotalValue()), and list the portfolio's holdings (listStocks()).

II. Utilizing Switch Statements:

Switch statements were employed for user interaction within the application. For example:

  • User Actions: When users interact with the application, they select actions such as adding stocks from their portfolio. We use switch statements to route these actions to the appropriate methods, providing a clear and intuitive user experience.

III. Error Handling with Try-Catch-Finally:

To enhance the robustness of our application, we implemented error handling using try-catch-finally statements. Here's how they were integrated:

  • Insufficient Funds: When users attempt to purchase stocks with insufficient funds, we employ try-catch blocks to handle this scenario gracefully, providing informative error messages.
