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 Divide Add Subtract Multiply Divide 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)?
