Sample Guidelines for GUI Programming

Appendix ‘B’

1. To display a message using Label, TextBox, MessageDialog using simple GUI applications

2. To concatenate two text entries and display using simple GUI application

3. To perform a simple arithmetic operation (+,-,*,/) and display the result in MessageDialog or TextBox using simple GUI application

4. To perform simple arithmetic operation (+,-,*,/) and display the result in TextBox using simple GUI

application

5. To make simple decision making (if statement) solution and display relevant message using GUI application (Example – Problems related to Eligibility for a given value of Age, “Profit” or “Loss” messages for given values of Cost Price and Sale Price, Grade Display for given values of Marks of students etc.)

6. To create a simple GUI application to perform both arithmetic and logical operation together (Example

– Total, Average and Grade calculation for given marks, Salary Calculation on different criteria)

7. To create a simple GUI application to perform an operation based on the criteria input by the user in a CheckBox or a RadioButton.

(Example 1: Find the Discount of an item on the basis of Category of item [Electrical Appliance/Electronic Gadget/Stationary specified using a Radio button] and its Cost [Below 1000/Above 1000/Equal to 1000 specified using a Radio button]).

(Example 2: Calculate the incentive of a Sales Person on the basis of his Sales Amount, Customer Feedback, Count of Customer specified using CheckBox)

8. To create a simple GUI application to change the property of a swing element based on the selection made by the user

(Example 1: To change the background or Foreground color of any of the Swing elements of the form based on the color selected from a list)

(Example 2: To change the foreground and background color of a label based on the values input/stored in a combo box)

9. To create a simple GUI application for repeatedly doing a task based on the user input. (Example: To display the multiplication table of a number input by the user)

10. To store the data (Admission No., Name, Date of Birth, Class and Section) of 10 students in a table

[Table] and find total number of students in each class and section.

Sample Guidelines for Connectivity Problems

11. To create a simple GUI application that counts and displays the number of records present in a database table.

12. To create a simple GUI application that displays the records of a database table in a tabular format (using jTable) on the GUI form.

13. To create a simple GUI application that displays the records of a database table in a tabular format (using jTable) on the GUI form based on a criteria input by the user.

14. To create a simple GUI application to perform a calculation based on a value retrieved from database table and a value entered by the user in a GUI application.

Know More (beyond syllabus):

· Teachers may also motivate students to search for topics of emerging ICT technologies such as Web Services, Cloud Computing, SDK on Android etc. for group discussions and presentations.

· Students may be encouraged for collaborative programming and remote trouble shooting.
