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.

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.
