Objective/Purpose of the program 

Briefly describe the program’s requirements. 

Analysis/Design   

Describe the approach/structure of program. What classes/functions were used?  

 

 

Testing/Results 

Does your program satisfy all requirements of the lab? 

If yes, how did you test it? Indicate test cases used, expected values, and show results with screen shots.  For example: 

 

Case	Description	Test Data	Expected Result	Actual Result
1	Describe what you are testing	Specify the test data	What is expected	Actual results – reference an image that you include below.

 

If any requirements are NOT met, document the known issues.  What did you do to try to solve them? 

Make sure you demonstrate in your testing the parts that are working correctly. 

 

Conclusions / Lessons Learned 

What difficult problems did you encounter, and how did you handle them? 

What new concepts did you learn/reinforce with this lab? 

Is there anything you would have done differently? 

 

 

OBJECTIVES 

• Create a GUI that uses JList and JTabbedPanes. 
• Process multiple objects in an ArrayList. 
• Code event handlers for multiple events. 

 

 

PROBLEM: Stocks4U Portfolio Management System 

Stocks4U needs to develop an app for you to manage your stock purchases. You should be able to store a list of stock purchases, view the individual stocks, add and remove stocks. 

 

FUNCTIONAL REQUIREMENTS 

You can code the GUI by hand or use NetBeans GUI builder interface. 

 

The GUI should have two tabs using JTabbedPane. 

• One tab (“Show stocks”) should have  
  • a JList to display all the stock purchases; 
  • a text field or label to display information about a particular stock; and 
  • a JButton to remove a stock. 
• One tab (“Add stock”) should have textboxes, labels, and a button to input a stock. 

 

Create a Stock class to manage the stock activity. It should have private instance variables of 

• company name; 
• number of shares; 
• purchase price; and 
• current price. 

Create a default and parameterized constructor. 

Create sets/gets for all instance variables. 

Create a get method to calculate and return the profit or loss. This would be calculated as 

            Number of shares * (current price – purchase price). 

Create toString to display the name of the stock. 

 

As you add stocks, they are displayed in the JList. 

If you select an element in the JList, the gain or loss is displayed in the label or text field. 

If you select an element in the JList and click Remove, the stock is removed from the list.
