Homework #2

Create a GUI front end for Homework #1. See details below.

1. Create a GUI that has two check boxes which allow a user to select between an employee and a manager. (20 points)

2. Create a GUI that pops up ONLY if the employee box is selected. This new window should contain JLabels with JTextFields that allow the user to enter in all the employee's relevant information - e.g. Name, Title, Age, and Salary. Use the same inputs from the Jane Doe case in Homework #1. The new window should also allow the user to raise the employee's salary by a certain percentage - JTextField (% Increase). Use the employee raiseSalary(int percent) method from Homework #1. Lastly, the new window should include a calculate button which computes and outputs the new salary when pressed. In this case, the new salary would be 82125.0. (20 points)

3. Create a GUI that pops up ONLY if the manager box is selected. This new window should contain JLabels with JTextFields that allow the user to enter in all the manager's relevant information - e.g. Name, Title, Age, Years of Experience, Highest Degree Earned, Salary, and Promotion Bonus. Use the same inputs from the John Doe case in Homework #1. The new window should also allow the user to raise the manager's salary by a certain percentage - JTextField (% Increase). Use the manager raiseSalary(int percent) method from Homework #1. Lastly, the new window should include a calculate button which computes and outputs the new salary when pressed. In this case, the new salary would be 114500.0. (20 points)

4. Create a GUI error message that pops up if the user enters invalid information into the GUI from question #2. (20 points)

5. Create a GUI error message that pops up if the user enters invalid information into the GUI from question #3. (20 points)

Develop a report that contains an overview of the source code. It should also include print screens of the GUIs from each scenario mentioned above. Copy source code and paste in the report's Appendix similar to what was provided in the Homework #1 assignment. Note, all responses should be contained in ONE WORD or PDF document. Other formats will not be accepted.

homework #1 is given below

Homework #1

Please refer to the code in the Appendix (pages 2 - 6) to answer the following questions

. 1. What is the relationship between the Employee class and the Manager class? What concept does this demonstrate? (10 points)

2. What would happen if mySalary were declared private instead of protected? (15 points)

3. Write the output for each section of print statements. (15 points)

4. Which raiseSalary() method does m.raiseSalary(10) execute? Why? What concept does this demonstrate? (20 points)

5. Which raiseSalary() method does e1.raiseSalary(10) execute? Why? What concept does this demonstrate? (20 points)

6. Which raiseSalary() method does e2.raiseSalary(10,1) execute? Why? What concept does this demonstrate? (20 points)
