Chapter 13, Problem 5AW
Program Plan Intro
Retrieving the selected item:
- The user can retrieve the selected item either by “getSelectedValue” method or “getSelectedIndex” method.
- The “getSelectedValue” method is used to return a reference to the item that is currently selected.
- The “getSelectedIndex” method is used to determine which item in a list is currently selected.
Example:
The example for “getSelectedIndex” method:
//create an array "fruit" and add the items
String[] fruit = {"Apple", "Orange", "Bananas", "Grape"};
//create a " JComboBox " named "fruitList".
JComboBox fruitList = new JComboBox (fruit);
//declare the integer variable
int x;
//determine the item in a list
x = fruitList.getSelectedIndex ();
- Initially declare an array “fruit” and add the items to the list.
- The “fruitList” is a “JComboBox” object and pass an array of “String” objects to the “JComboBox” constructor.
- Declare the “x” variable and determine the item in a list by calling “getSelectedIndex” method.

Extra 6-1 Develop the Temperature Converter
In this exercise, you’ll use radio buttons to determine whether the conversion is from Fahrenheit to Celsius or vice versa. You’ll also modify the DOM so the labels change when a radio button is clicked, and the page displays an error message when the user enters invalid data.
1. Open the application in this folder:
exercises_extrach06convert_temps
2. Note that the JavaScript file has some starting JavaScript code, including the $() function, three helper functions, three event handler functions, and a DOMContentLoaded event handler that attaches the three event handlers.
3. Review how the toCelsius() and toFarhenheit() event handler functions call the toggleDisplay() helper function and pass it strings to display. Also note that the toggleDisplay() helper function and the convertTemp() event handler function are incomplete.
4. Code the toggleDisplay() function so it changes the text in the labels for the text boxes to the values in the…
