The document serves as a comprehensive tutorial on Java Swing, detailing its components and functionalities for creating graphical user interfaces (GUIs) in Java. It covers various aspects such as event handling, different layout managers, and the integration with JDBC for database connectivity. Additionally, it provides practical examples and syntax for common SQL operations and database management using MySQL.

1. Java Swing Tutorial

2. Java Swing
* A part of The JFC
* Swing Java consists of
Look and feel
Accessibility
Java 2D
Drag and Drop, etc

3. Introductions

Swing is one of the Graphical User Interface tool.

Swing is used to develop the graphical user interface (GUI) in
java.

Swing components used for the building of GUI.

Swing components are helpful for interactivity to Java
applications.

The components of Swing toolkit are given below:
list controls
buttons
labels
tree controls
table controls

4. Java Swing Class Hierarchy

5. Swing Events

event source // The Event source is the object. It generates
Events.

event object // The Event object encapsulates the condition
changes in the event source.

event listener // The Event listener is the object that requests
to be notified
Event source:

Object is handling an event to the event listener.Event
handling in Swing toolkit is very easy to handle and powerful.

Objects are notified when a specific event occurs.

6. JFrame

Open frame place the icon on the title bar.Methods
are as follows:

frame.setIconImage(Toolkit.getDefaultToolkit().getI
mage("icon_confused.gif"));

it’s using the Image class method named
getImage().frame.getDefaultToolkit():
//This is the method of the Toolkit class which gets
the default toolkit.

7. createAndShowGUI
private static void createAndShowGUI()
{
//Create and set up the window.
JFrame frame = new JFrame("Hi..");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Add a label.
JLabel label = new JLabel("Hello World");
frame.getContentPane().add(label);
//Display the window.
frame.pack();
frame.setVisible(true);
}

8. Menus
JMenuBar
JMenu
JMenuItem

9. checkBox
import javax.swing.*;
JCheckBox chk = new JCheckBox("This is the
Check Box");
frame.add(chk);

10. Text Area
import javax.swing.JTextArea;
// Create a text area with some initial text
JTextArea textarea = new JTextArea("Initial
Text");
int rows = 20;
int cols = 30;
textarea = new JTextArea("Initial Text", rows,
cols);
TextField
JTextField t = new JTextField("Text field 3", 8);

11. JButton
Button:
Two types: JButton(), JButton(Name)
JButton () is used for create blank JButton instance.
JButton (Name) is used for create a JButton
instance with the specified text.
JButton Button1;
Button1 = new JButton ("Black is White");
add (Button1);

12. Layout Managers

Most Swing UIs utilise a LayoutManager to control
positioning of items

There is a choice of these which work in different
ways

Initially we do without one, and position items
ourselves:

frame.setLayout(null);

13. Absolute positioning
JFrame frame = new JFrame("I am a JFrame");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setBounds(20,30,300,100);
frame.setLayout(null);
JButton butt=new JButton("Click me");
frame.getContentPane().add(butt);
butt.setBounds(20, 20, 200,20);
frame.setVisible(true);

14. FlowLayout
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame frame = new JFrame("FlowLayout");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(new FlowLayout());
JButton b1 = new JButton("Hello");
frame.getContentPane().add(b1);
JButton b2 = new JButton("Two");
frame.getContentPane().add(b2);
JTextField t1 = new JTextField("Text here");
frame.getContentPane().add(t1);
frame.pack();
frame.setVisible(true);

15. BorderLayout
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame frame = new JFrame("Border");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JButton b1 = new JButton("At the top");
frame.getContentPane().add(b1,BorderLayout.PAGE_START );
JButton b2 = new JButton("Bottom");
frame.getContentPane().add(b2,BorderLayout.PAGE_END);
JTextField t1 = new JTextField("Left");
frame.getContentPane().add(t1,BorderLayout.LINE_START);
JTextField t2 = new JTextField("Right");
frame.getContentPane().add(t2,BorderLayout.LINE_END);
JButton b3 = new JButton("Centre");
frame.getContentPane().add(b3,BorderLayout.CENTER );
frame.pack();
frame.setVisible(true);

16. Grid Layout
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame frame = new JFrame("Grid");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(new GridLayout(4,3,5,5));
for (int i=0; i<10; i++)
frame.getContentPane().add(new JButton(""+i));
frame.pack();
frame.setVisible(true);

17. Swing has a lot of classes
controls
User I/O widgets
eg JButton
containers
things that hold other things
eg JFRame

18. Containers
general purpose containers -
panel
scroll pane
split pane
tabbed pane
tool bar
top level containers - JFrame JApplet JDialog

19. JPanel ( in createAndShowGUI)
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame frame = new JFrame("I am a JFrame");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setBounds(20,30,300,100);
frame.setLayout(null);
//Create a panel
JPanel myPanel = new JPanel();
myPanel.setBackground(new Color(255,3,25));
myPanel.setOpaque(true);
//Make it the content pane.
frame.setContentPane(myPanel);
frame.setVisible(true);

20. Tooltip and border
myPanel.setOpaque(true);
myPanel.setToolTipText("I'm a JPanel");
myPanel.setBorder(BorderFactory.createLineBor
der(Color.white));
frame.setContentPane(myPanel);
..

21. JSplitPane
setLayout(null);
//Create a split pane
JSplitPane myPane = new JSplitPane();
myPane.setOpaque(true);
frame.setContentPane(myPane);
frame.setVisible(true);

22. JSplitPane with JPanels
//Create a split pane
JSplitPane myPane = new JSplitPane();
myPane.setOpaque(true);
myPane.setDividerLocation(150);
// make two panels
JPanel right = new JPanel();
right.setBackground(new Color(255,0,0));
JPanel left = new JPanel();
left.setBackground(new Color(0,255,0));
// set as left and right in split
myPane.setRightComponent(right);
myPane.setLeftComponent(left);

24. JDBC (JAVA DATABASE
CONNECTIVITY)

25. Database and Database
Management System
 Database is simply a collection of data. In relational database,
data is organized into tables.
 Database Management System (DBMS) is software to maintain
and utilize the collections of data (Oracle, DB2, MySQL)
Student_ID Name Major Grade
101 Shannon BCB A
102 Mike BBMB A
103 Wang MCDB A
… … …

26. MySQL Introduction
 MySQL is a database management system
 SQL stands for the Structured Query Language.
It defines how to insert, retrieve, modify and
delete data
 Free from www.mysql.com

27. Introductions

JDBC is Java application programming interface

Allows the Java programmers to access database
management system from Java code.

To execute SQL statements

28. Components of JDBC
JDBC has four Components:
1. The JDBC API.
2. The JDBC Driver Manager.
3. The JDBC Test Suite.
4. The JDBC-ODBC Bridge.

29. Type 1 JDBC Architecture

30. Type 2 Java to Native API

31. Type 3 Java to Network Protocol
Or All- Java Driver

32. Type 4 Java to Database Protocol

33. Common SQL statements
SQL Select statement:
The SELECT statement is used to select data from
a table.
Syntax: Select column_names FROM table_name;

34. SQL INSERT Statement
To insert a single or multiple records into the database.
Syntax: Insert into table_name values(value1,value2..);
The Insert statement has mainly three clauses.
1). Insert: It specifies which table column has to be inserted
in the table.
2). Into : It tells in which the data will be stored.
3). Values: In this we insert the values we have to insert.

35. UPDATE Statement
The Update statement is used to modify the data
in the table
The syntax is :
UPDATE table_name Set colunm_name =
new_value WHERE column_name = some_name;

36. DELETE Statement
This delete statement is used to delete rows in a
table.
Systax:
DELETE FROM table_name WHERE
column_name = some_name;

37. Login
 mysql –h hostname –u username –p
[password]
 Example
% mysql -u usrname -p
Enter password: passowrd
Welcome to the MySQL monitor. Commands
end with ; or g. Your MySQL connection id is
23 to server version: 3.23.41.
Type 'help;' or 'h' for help. Type 'c' to clear the
buffer.

38. Login Example
 Exp:2
mysql –h 131.131.0.103 –u amudha –p
amudha1
 mysql>

39. mysql> show databases; (What are the current databases at the server?)
+--------------+

47. Steps to creatd JDBC

Tables creation

Load the driver manager

Connection establishment

Statement creations

Process the result set

Execute the statement

Close the connection and statement

Stop the program

48. Creating a Database Table
String table ;
table= "CREATE TABLE
Employee11(Emp_code integer, Emp_name
varchar(10))";
st.executeUpdate(table);

49. Connection Establishment

Is an interface in java.sql package
Specifies connection with specific database
like: MySQL, Ms-Access, Oracle etc and java
files.

The SQL statements are executed within the
context of the Connection interface.

Class.forName(String driver):

50. Connection Establishment
 Syntax
Connection conn;
Class.forname(“com.mysql.jdbc.Driver”).newIns
tance();

51. DriverManager

It is a class of java.sql package that controls a set
of JDBC drivers.

Each driver has to be register with this class.

getConnection(String url, String userName,
String password):

url: - Database url where stored or created your
database

userName: - User name of MySQL

password: -Password of MySQL

52. Load the JDBC Driver into the database
 Syntax
String userName = "root";
String password = "mysql";
String url =
"jdbc:mysql://localhost/programs";
 conn =
DriverManager.getConnection(url,userNa
me,password);

53. Create the statements and update the
values in the table structure
 Statement st=conn.createStatement();
 st.execute("create table stud10(rollno
int,name text,m1 int,m2 int)");
 st.executeUpdate("insert into stud10
values(2,'rani',50,90)");

54. Process the Query result set
rs=st.executeQuery("select * from stud10");
while(rs.next())
{
System.out.println(rs.getInt(1));
System.out.println(rs.getString(2));
System.out.println(rs.getInt(3));
System.out.println(rs.getInt(4));
}

55. Close the connection

con.close():

This method is used for disconnecting the
connection.

It frees all the resources occupied by the
database.

56. Close the statement and connection
 st.close();
 conn.close();

57. Final Steps
 To import Syntax
export
CLASSPATH=$CLASSPATH:/usr/share/java/my
sql-connector-java-5.1.6.jar
 To Compile
Javac Filename.java
 To Run
java Filename
