![]() Import javax.swing. JComboBox jc = new JComboBox(name) //initialzing combo box with list of name.Ī program to change background color of a frame (Using Action Event) import java.awt.* //importing awt package Combo box is used to create a drop-down menu. Lets create an example to add combobox to the jframe. Following is the constructor for JComboBox, JComboBox(String arr) Example using JComboBox JComboBox component is used to create a combo box in Swing. Jcb = new JRadioButton("C") //creating JRadioButton.Ĭombo box is a combination of text fields and drop-down list. Jcb = new JRadioButton("B") //creating JRadioButton. JRadioButton jcb = new JRadioButton("A") //creating JRadioButton.Īdd(jcb) //adding JRadioButton to frame. It is used to get single user response at a time. To create radio button in swing, we used jradiobutton class. Following is the constructor for JRadioButton, JRadioButton(String str) Example using JRadioButton JRadioButton class is used to create a radio button in Frames. Radio button is a group of related button in which only one can be selected. Jcb = new JCheckBox("maybe") //creating JCheckBox. Jcb = new JCheckBox("no") //creating JCheckBox. JCheckBox jcb = new JCheckBox("yes") //creating JCheckBox. JCheckBox(String str)using JCheckBox import javax.swing.* In this example, we are creating three checkboxes to get user response. The JcheckBox class is used to create chekbox in swing framework. SetDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) JTextField jtf = new JTextField(20) //creating JTextField. In this example, we are creating text field using JtextField class and adding into the jframe container. It has three constructors, JTextField(int cols)Ĭols represent the number of columns in text field. JTextField is used for taking input of single line of text. SetSize(400, 400) //setting size of Jframe SetLayout(new FlowLayout()) //setting layout using FlowLayout object SetDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) //setting close operation. JButton bt2 = new JButton("No") //Creating a No Button. JButton bt1 = new JButton("Yes") //Creating a Yes Button. In this example, we are creating two buttons using Jbutton class and adding them into Jframe container. JButton class has three constuctors, Example of JButton Swing JButton JButton class provides functionality of a button. It can be used to organize related components together.It cannot be contained within other containers.It inherits Component and Container of AWT.It provides a space where a component can be managed and displayed. The value of the alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, FlowLayout.CENTER, FlowLayout.LEADING, or FlowLayout.TRAILING. This class provides some common functionality like pluggable look and feel, support for accessibility, drag and drop, layout, etc.Ī container holds a group of components. Constructs a new FlowLayout with the specified alignment and a default 5-unit horizontal and vertical gap. ![]() All these components are lightweight components. They all are derived from JComponent class. Connecting to Access using Type-1 DriverĪ component is an independent visual control and Java Swing Framework contains a large set of these components which provide rich functionalities and allow high level of customization.Method Overriding with Exception Handling.Difference between Classes And Interface.
