Launch NetBeans. Click File > New Project > Java Application > Next. The project name should be EventDriven_(LastName) (ex. EventDriven_Reyes). Then, click Finish. Create a simple program that includes JFrame, JPanel, JLabel, JFields, JTextArea, and JButton. The program should ask the user for the following input: First name Last name Middle name Mobile number E-mail Use the following methods and classes in creating the program: public class EventDriven extends JFrame This should be the main class of the program and should contain the list of components and its corresponding declaration. public EventDriven This method should include the formatting of components in the INPUT frame. class btnSubmit implements ActionListener This class should be within the public class EventDriven extends JFrame and should contain the actions that would be performed by the Submit button in the INPUT frame. class btnClearAll implements ActionListener This class should be within the public class EventDriven extends JFrame and should contain the actions that would be performed by the Clear All button in the INPUT frame. class btnOkay implements ActionListener This class should be within the public class EventDriven extends JFrame and should contain the actions that would be performed by the Okay button in the OUTPUT frame. public static void main (String[] args) This will serve as the main method of the program. Two (2) frames will be used in this program: OUTPUT and INPUT. The following conditions must be satisfied by the
Hands-on Activity
Application of Event -Driven Programming
Objectives:
At the end of the exercise, the students should be able to:
- Describe the event handling process; and
- Incorporate events in a
Materials:
- One (1) personal computer with NetBeans IDE and Java Development Kit (JDK) 8
- Internet connection
Instructions:
- Launch NetBeans. Click File > New Project > Java Application > Next. The project name should be
EventDriven_(LastName) (ex. EventDriven_Reyes). Then, click Finish.
- Create a simple program that includes JFrame, JPanel, JLabel, JFields, JTextArea, and JButton. The program should ask the user for the following input:
- First name
- Last name
- Middle name
- Mobile number
- Use the following methods and classes in creating the program:
|
public class EventDriven extends JFrame |
This should be the main class of the program and should contain the list of components and its corresponding declaration. |
|
public EventDriven |
This method should include the formatting of components in the INPUT frame. |
|
class btnSubmit implements ActionListener |
This class should be within the public class EventDriven extends JFrame and should contain the actions that would be performed by the Submit button in the INPUT frame. |
|
class btnClearAll implements ActionListener |
This class should be within the public class EventDriven extends JFrame and should contain the actions that would be performed by the Clear All button in the INPUT frame. |
|
class btnOkay implements ActionListener |
This class should be within the public class EventDriven extends JFrame and should contain the actions that would be performed by the Okay button in the OUTPUT frame. |
|
public static void main (String[] args) |
This will serve as the main method of the program. |
- Two (2) frames will be used in this program: OUTPUT and INPUT. The following conditions must be satisfied by the
Input Frame:
- Set the window name to INPUT.
- The input frame should collect all the details listed on Step
- It should contain Submit and Clear All
- When the Submit button is clicked, it should generate the output frame and disable the
Submit button.
- When the Clear All button is clicked, it should clear all the content that were entered by the user in the input frame, and close the output frame if it is
Output Frame:
- Set the window name to OUTPUT.
- The output frame should display all the details that were entered by the user with the corresponding label.
- The output frame should contain an Okay
- When the Okay button is clicked, it should automatically close the output frame and clear the content of the input
- See Figures 1 and 2 below for the expected
Figure 1. L–R: Initial output of the program with the input window; text fields with sample input
Figure 2. After clicking the submit button, the program should generate the output window (image on the right) and disable the submit button (image on the left).
Note: Clicking the Okay and Clear All buttons will refresh the program and generate the image on the left under Figure 1.
- Use your personal information in filling out the input Screenshot your code and output.
