Chapter 13, Problem 3AW

Explanation of Solution

List creation:

• To create a list, Java provides a component called “JList”.
• A list of items can be displayed by “JList” component.
• A “JList” component allows the user to choose one or more items from the list.
• To create a list of items, “JList” component uses an array.
• An array of “String” objects is passed to the constructor, when “JList” class is instantiated.
• Code to create a list with the items is as follows:

//Create String object

String[] days = { "Monday", "Tuesday", "Wednesday",

   "Thursday", "Friday", "Saturday", "Sunday"};

//Call "JList" constructor

JList days_list = new JList(days);

• If a list component contains too many items to be displayed at once, then Graphical User Interface (GUI) application display a scroll bar...
