Here is an example of how to define the selection mode of a list in Java: tSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION) These three selection modes are constants defined in the ListSelectionModel that manages them. MULTIPLE_INTERVAL_SELECTION: A user can make any combination of selections.SINGLE_INTERVAL_SELECTION: A user can select multiple contiguous or sequential items.SINGLE_SELECTION: A user can only select one list item at a time.There are three selection modes for Java lists: It defines the number of selections a user can make and whether or not they are contiguous or in sequence. The setSelectionMode() method allows you to do this. When dealing with a list in Java, it is necessary for you to define how the user makes selections (provided you want to allow this functionality, mind). How to Allow User Selections on Java Lists In the above Java code, we initialized our Jlist model with the items in the fruits list. You can then initialize your list using the strings passed from another object (for example, fruits in the example below): JList list = new JList(fruits) If you wish to remove an item from the list, then you simply use the remove() method and provide the index of the element as the parameter, as shown in the following code example: fruits.addElement("banana") You can add items to your model using the addElement() method. How to Initialize and Select List Items in a Java Model Here is an example of its syntax in Java: DefaultListModel fruits = new DefaultListModel() // sample usage The examples in this tutorial will be using the DefaultListModel. JList models allow your program to keep track of items added to – or selected on – the list. ListModel: Gives you complete control over everything.AbstractListModel: Allows you to invoke “fire” methods and manage your data.DefaultListModel: This is the simplest model to use and it handles everything for you.Read: How to Create a Java ArrayList Class How to Create a Model in JavaĪ model allows your program to track an object’s state. In this Java programming tutorial, we will discuss how coders can use JList in graphical user interface (GUI) applications. Lists are normally put in scroll panes since they can contain many items. It enables programmers to create a list of items from which a user can choose an option. Java allows developers to create lists for their graphical applications using the JList class, which is a subclass of the JComponent class.
