Swings

Swing is also part of Sun Microsystems' Java Foundation Classes (JFC) — "an Application Programming Interface (API) for providing a graphical user interface (GUI) for Java programs" , introduce to overcome the limitation of AWT. The Swing classes are built on top of the AWT architecture. The JFC also provide some other important features to a GUI program, like the ability to add rich graphics functionality, ability to create a program that can work in different languages/platform, and by users with different input devices.

Write a program that "display the component in Jframe".
Use the following program

/*
 * Save as a FirstFrame.java
 * Program that display All the Component.
 */
package r4r.co.in;

import java.awt.Color;
import javax.swing.*;

public class FirstFrame extends java.awt.Frame {

    //Define the Component and used it into the program
    private JLabel label;
    private JButton button;
    private JTextField field;
    private JTextArea area;

    public FirstFrame() {
        init();
    }

    private void init() {
        JFrame frame = new JFrame("Frame in Component of AWT ");
        JPanel panel = new JPanel();
        frame.setVisible(true);
        frame.setBounds(300, 400, 300, 400);
        panel.setBackground(Color.orange);
        panel.setLayout(null);

        //Initilizad the Component

        label = new JLabel("R4R Tech Soft! Welcome");
        field = new JTextField("This is TextField", 20);
        button = new JButton("Click Me");
        area = new JTextArea(null, "This is TextArea", 4, 5);

        //Add the component into panel to display inside the JFrame
        label.setBounds(30, 20, 300, 30);
        panel.add(label);

        field.setBounds(25, 50, 200, 30);
        panel.add(field);

        button.setBounds(30, 100, 150, 50);
        panel.add(button);

        area.setBounds(20, 180, 200, 100);
        panel.add(area);

        //Add panel to the Frame alongwith its component
        frame.getContentPane().add(panel);
       //Free all the resource and unload the JFrame
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public static void main(String[] args) {
        FirstFrame firstFrame = new FirstFrame();
    }
}

OUTPUT: 
       

Difference Between Swing And AWT.

Difference between them-

Swing	Abstract Window Toolkit( AWT)
Swing classes define in the javax.swing  package. It is totally platform independent. Written entirely in Java programming language. Build around the number of API that implement various part of the AWT. Swing is Light weight component. It is "borrows" the screen resource of an ancestor ( means it has no native resource of its own).	AWT classes define in the java.awt package include subpackage java.awt.event It is not totally platform independent. Some AWT component use native code. Swing classes are built on top of the AWT architecture.  AWT are heavy weight components. It is associated with its own  native screen resource (commonly known as a peer).
