Exercise 1

Implement a basic stock trade application starting from the example provided in package exercise 1.

The aplication should provide following functionalities:

• View market stocks and their current value - this feature is implemented and can be used as reference for next points;

• View user portofolio owned stocks
  • View owned stocks in a table view similar with Market;
  • For each owned stock display in table followings: symbol, name, quantity, current market value (quantity * price);

• Buy stock:
  • Implement "Buy" button functionality;
  • Buy is limited by available cache funds (stored in Portofolio class, attribute "funds");

• Sell stock
  • Create user interface similar with Buy interface
  • Symbol dropdown button should display only stocks owned by user;
  • When sell is complete funds will automatically be increased with stock quantity * price;

For implementing user interface use Netbeans 12.6 and UI designer facility. All user interface should be implemented in the provided StockMarketJFrame class.

Implementation notes

Note 1 - Stock symbols are hardcoded in StockMarketQueryService private String[] symbols = new String[] {"INTC", "BABA", "TSLA", "AIR.PA", "MSFT", "AAPL"}; You can add your own symbol as long as correspond to some real market symbols.

Note 2 - For understanding how table model is created and how query service is integrated with the user interface view last year course starting with minute 15:00 here -> https://bit.ly/35X9YhN

Note 3 - For getting financial market information the application use https://financequotes-api.com/ library:

    <dependency>
        <groupId>com.yahoofinance-api</groupId>
        <artifactId>YahooFinanceAPI</artifactId>
        <version>3.15.0</version>
    </dependency>
