Chapter 13, Problem 10AW
Explanation of Solution
Lambda expression in JavaFX application:
- Lambda expression can be used to simplify coding for event handling.
- Using a lambda expression, user can create and register an event handler for the particular control in a JavaFX application.
Example:
The example for lambda expression is shown below:
radiobutton1.setOnAction(event ->
{
displayLabel.setText("The given option is selected");
});
Here,
- The “radiobutton1” represents the name of a RadioButton control.
- The “displayLabel” represents the name of a Label control.
- Defines the given text “The given option is selected” in “TextArea” control using “setText()” method.
Lambda expression to register an event handler with the “RadioButton” control:
radio1...

Program Description: PasswordGenerator.java
You have to implement a program that
creates three buttons to display the digits of a password
a button to generate a password
a button to reset the password
Additional Requirements:
The top three digit buttons are not interactive as they are only used to display numbers from 0 to 9.
The text size of the buttons should be 30 pixels and font should be Arial.
There should be 5 pixels distance between the buttons.
Lab 12 - Advanced JavaFX Controls
Part 1:
Make a new copy of the JavaFX program SimpleCalculator that you developed in Lab 11, then
add to it a menu with four menu items as shown below. This menu should allow a user to
perform addition, subtraction, multiplication, and division.
Simple Calculator
I Simple Calculator
Operation
Operation
First Number:
Add
Ctrl+A
Subtract Ctrl+S
Second Number:
Multiply Ctrl+M
Result:
Divide
Ctrl+D
Add Subtract Multiply

Add

Discuss:
1. Where to place the menu bar? Is the menu bar should be placed at the top of
the border pane?
2. Is it better to use methods for implementing addition, subtraction,
multiplication, and division tasks and call those methods whenever they are
needed instead of rewriting the same code once for the buttons and again
for the menu items?
3. How can you assign keyboard accelerator to a menu item (such as: Ctrl+A to
Add)?
