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.

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.

//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.
