1. Advance Java Technology Java’s Role::MVC Architecture :: Swing Prof.Chintan Dave

2. Who is the Founder of Java???????

3. Which is the Most Popular Machine Used in Day to Day Life Uses Java????????

4. Which is the Most Popular OS Uses Java as Prime Framework ???

5. Most Popular Companies uses Java as Prime Technology… Google Yahoo Microsoft LinkedIn……………..endless list

6. Usage wise Programming Languages/Technologies

7. Common Architecture for Any Programming Technology Operating System Run Time Environment Class Libraries Application

8. Java Architecture Operating System- Windows,Mac,Solaris… Run Time Environment-JVM Class Libraries-Packages Application-Windows,Web, Mobile …….

9. How Application Can be Developed - Traditional Way of Developing an Application with Forms…Approach -Developing an Application with MVC Architecture None is Best None is Worst Too--- Its Just on Requirements… or Approach for an Application

10. MVC Architecture a software design pattern for developing web applications. Model - The lowest level of the pattern which is responsible for maintaining data. View - This is responsible for displaying all or a portion of the data to the user. Controller - Software Code that controls the interactions between the Model and View.

11. What is Swing???? It is a SET of Programs which provides facility to Create GUI. It is a Widget Toolkit It is Part of JFC(Java Foundation Classes It is Useful for Creating Rich Set of Desktop Application IT MEANS it’s a PURE JAVA

12. What You Need to Run Java- SWING JAVA SE- which can be downloaded from java.sun.com/javase To Make Java Code You’ll Need an Editor….Most Popular Once are….. Notepad Eclipse Net beans JCreator

13. Pluggable Look n Fell Pluggable L&F (PLAF) is basically a "skin" system for Swing components - you can change the style of your application by changing its LAF Allows an Application Development to Highly Interactive GUI Component and Effects with ready made set of APIs

14. Applet Vs Swing SwingApplet Swing have its own Layout like most popular Box Layout. Applet uses AWT Layouts like flowlayout. Swing is light weight Component. iTS Heavy Weight Swing uses for stand lone Applications, Swing have main method to execute the program Applet need HTML code for Run the Applet Swing Uses MVCApplet Does not

15. Swing Features Lightweight - Swing component are independent of native Operating System's API as Swing API controls are rendered mostly using pure JAVA code instead of underlying operating system calls. Rich controls - Swing provides a rich set of advanced controls like Tree, Tabbed Pane, slider, color picker, table controls Highly Customizable - Swing controls can be customized in very easy way as visual appearance is independent of internal representation.

16. To Use Swing Components.. Create an Object of Component For Example: JButton but = new JButton(); Adding Component For Example: Container cp = getContentPane(); cp.add(new JButton(“but”)); Laying Out Component Not so difficult but takes a little practice JPanel p1 = new JPanel(); p1.setLayout(new FlowLayout(FlowLayout.LEFT));

17. Simple Swing Example import javax.swing.*; public class Simple { JFrame f; Simple() { f=new JFrame(); JButton b=new JButton("click"); b.setBounds(130,100,100, 40); f.add(b); f.setSize(400,500); f.setLayout(null); f.setVisible(true); } public static void main(String[] args) { new Simple(); } }

18. JLabel The class JLabel can display either text, an image, or both Example code: import javax.swing.*; class hello { public static void main(String[] args){ JFrame f = new JFrame(“title”); JPanel p = new JPanel(); JLabel b = new JLabel(“Demo Label”); p.add(b);// add labelto panel f.setContentPane(p); // add panel to frame f.show(); }

19. JButton The class JButton is an implementation of a push button. It can have Image also

20. Code - JButton import javax.swing.*; public class SimpleButton { JFrame f; SimpleButton() { f=new JFrame("Simple Button Example"); ImageIcon india = new ImageIcon("india.jpg"); JButton jb = new JButton("Our Flag",india); JButton b=new JButton("click"); f.add(b); f.add(jb); b.setBounds(130,100,100, 40); jb.setBounds(130,200,500,200); f.setSize(400,500); f.setLayout(null); f.setVisible(true); f.setDefaultCloseOperation(JF rame.EXIT_ON_CLOSE); } public static void main(String[] args) { new SimpleButton();} }

21. JTextfield The class JTextField is a component which allows the editing of a single line of text. Common Constructors:- JTextField(String text):- Constructs a new TextField initialized with the specified text.

22. Code - JTextField import java.awt.*; import java.awt.event.*; import javax.swing.*; //code that demonstrate use of JLabel,JButton,JTextfield and Sample GUI Application public class SimpleTextField { JFrame f; SimpleTextField() { //Setting Layout f=new JFrame("Simple Button Example"); JPanel controlPanel = new JPanel(); controlPanel.setLayout(new FlowLayout()); //Creating GUI Aspects for an Appllication JLabel lblUsername= new JLabel("Username:", JLabel.RIGHT); JLabel lblPassword = new JLabel("Password:", JLabel.CENTER); JTextField txtUsername = new JTextField(10); JTextField txtPassword = new JTextField(10); JButton btnLogin=new JButton("Login");

23. Code – JTextField-Continue //Adding Instance in Layout controlPanel.add(lblUsernam e); controlPanel.add(txtUsernam e); controlPanel.add(lblPassword); controlPanel.add(txtPasswor d); controlPanel.add(btnLogin); f.add(controlPanel); f.setSize(400,500); f.setVisible(true); f.setDefaultCloseOperation(JFra me.EXIT_ON_CLOSE); } public static void main(String[] args) { new SimpleTextField(); //calling GUI }

24. Event Handling What is an Event? Change in the state of an object is known as event. Types of Event The events can be broadly classified into two categories: Foreground Events - Those events which require the direct interaction of user. Background Events - Those events that require the interaction of end user are known as background events. Operating system interrupts

25. Code for Simple Even Handling import java.awt.*; import java.awt.event.*; import javax.swing.*; //code that demonstrate use of JLabel,JButton,JTextfield and Sample GUI Application public class SimpleButtonEvent { JFrame f; JLabel statusLabel=new JLabel("Your Status"); SimpleButtonEvent() { //Setting Layout f=new JFrame("Simple Button Example"); JPanel controlPanel = new JPanel(); controlPanel.setLayout(new FlowLayout()); //Creating GUI Aspects for an Appllication JButton btnOk=new JButton("Ok"); JButton btnCancle=new JButton("Cancle"); JButton btnRetry=new JButton("Retry"); //Adding Instance in Layout controlPanel.add(btnOk); controlPanel.add(btnCancle); controlPanel.add(btnRetry); btnOk.addActionListener(new ButtonClickListener()); btnCancle.addActionListener(new ButtonClickListener()); btnRetry.addActionListener(new ButtonClickListener()); controlPanel.add(statusLabel); f.add(controlPanel); f.setSize(400,500); f.setVisible(true); f.setDefaultCloseOperation(JFrame.EXIT _ON_CLOSE); }

26. Code for Simple Even Handling private class ButtonClickListener implements ActionListener{ public void actionPerformed(ActionEvent e) { String command = e.getActionCommand(); if( command.equals("Ok")) { statusLabel.setText("Ok Button clicked."); } else if( command.equals("Cancle") ) { statusLabel.setText("Cancle Button clicked."); } else { statusLabel.setText("Retry Button clicked."); } } public static void main(String[] args) { new SimpleButtonEvent(); //calling GUI }

27. JCheckBox The class JCheckBox is an implementation of a check box - an item that can be selected or deselected, and which displays its state to the user. Constructor- JCheckBox(String text): Creates an initially unselected check box with text. Method- getStateChange() – A Boolean Method to get the state of CheckBox Event- Listener Is – ItemListener Event is - ItemEvent

28. Code for Simple Checkbox import java.awt.*; import java.awt.event.*; import javax.swing.*; //code that demonstrate use of JLabel,JButton,JTextfield and Sample GUI Application public class SimpleCheckBox { JFrame f; SimpleCheckBox() { //Setting Layout f=new JFrame("Simple CheckBox Example"); JPanel controlPanel = new JPanel(); controlPanel.setLayout(new FlowLayout()); //Creating GUI Aspects for an Appllication JCheckBox chkApple = new JCheckBox("Apple"); JCheckBox chkMango = new JCheckBox("Mango"); JCheckBox chkBanana = new JCheckBox("Banana"); //Adding Instance in Layout controlPanel.add(chkApple); controlPanel.add(chkMango); controlPanel.add(chkBanana); chkApple.addItemListener(new ItemListener() { public void itemStateChanged(ItemEvent e) { f.setTitle("Apple Checkbox: " + (e.getStateChange()==1?"checked":"unchecked")); } }); f.add(controlPanel); f.setSize(400,500); f.setVisible(true); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } public static void main(String[] args) { new SimpleCheckBox(); //calling GUI }

29. JRadioButton Same as Checkbox But……Usage…is Different as per GUI’s Needs

30. JList The class JList is a component which displays a list of objects and allows the user to select one or more item Constructor:- JList()- Constructs a JList with an empty, read-only, model. Method:- addElement(String) – To add an Element in a List setSelectionMode()- selection mode for the list

31. Code for Simple List import java.awt.*; import java.awt.event.*; import javax.swing.*; //code that demonstrate use of JLabel,JButton,JTextfield and Sample GUI Application public class SimpleCheckBox { JFrame f; SimpleCheckBox() { //Setting Layout f=new JFrame("Simple CheckBox Example"); JPanel controlPanel = new JPanel(); controlPanel.setLayout(new FlowLayout()); //Creating GUI Aspects for an Appllication JCheckBox chkApple = new JCheckBox("Apple"); JCheckBox chkMango = new JCheckBox("Mango"); JCheckBox chkBanana = new JCheckBox("Banana"); //Adding Instance in Layout controlPanel.add(chkApple); controlPanel.add(chkMango); controlPanel.add(chkBanana); chkApple.addItemListener(new ItemListener() { public void itemStateChanged(ItemEvent e) { f.setTitle("Apple Checkbox: " + (e.getStateChange()==1?"checked":"unchecked")); } }); f.add(controlPanel); f.setSize(400,500); f.setVisible(true); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } public static void main(String[] args) { new SimpleCheckBox(); //calling GUI }

32. JComboBox Same as Jlist but Usage is Different- Usage is As per GUI NEED
