Chapter 13, Problem 4AW

Program Plan Intro

JList:

• “JList” is used to show a list of items.
• It is also used to permit the user to select one or more items from the list.
• A “JList” constructor is created with a help of “JList” class.
• When the user can create an object of the “JList” class, he passes an array of objects to the constructor.

Example:

The example for “JList” constructor:

//create an array "fruit" and add the items

String[] fruit = {"Apple", "Orange", "Bananas", "Grape"};

//create a "JList" named "fruitList".

JList fruitList = new JList (fruit);

• Initially declare an array “fruit” and add the items to the list.
• The “fruitList” is a “JList” object and pass an array of “String” objects to the “JList” constructor.
