Unit 1
Introduction
Practical 1: Write an applet that draws a circle. The dimension of the applet
should be 500 x 300 pixels. The circle should be centered in the applet and
have a radius of 100 pixels. Display your name centered in a circle.
(USING DRAWOVAL () method)
Practical 2: Draw ten red circles in a vertical column in the center of the
applet.
Practical 3: Built an applet that displays a horizontal rectangle in its center.
Let the rectangle fill with color from left to right.
Practical 4: Write an applet that displays the position of the mouse at the
upper left corner of the applet when it is dragged or moved. Draw a 10x10
pixel rectangle filed with black at the current mouse position.
Practical 5: Write an applet that contains one button. Initialize the label on
the button to “start”, when the user presses the button change the label
between these two values each time the button is pressed.
Practical 6: Write an applet that uses the mouse listener, which overrides
only two methods which are mouse Pressed and mouseReleased.
Exercise:
Unit 2
Introduction
Practical 7: Write a program that has only one button in the frame, clicking
on the button cycles through the colors: red->green->blue->and so on. One
color change per click. (use getBackGround() method to get the current
color)
Practical 8: Write an applet that contains three check boxes and 30 x 30
pixel canvas. The three checkboxes should be labeled
“Red”,”Green”,”Blue”. The selection of the check boxes determines the
color of the canvas. For example, if the user selects both “Red” and “Blue”,
the canvas should be purple.
Practical 9: Create an application that displays a frame with a menubar.
When a user selects any menu or menu item, display that selection on a text
area in the center of the frame
Practical 10: Write an applet that draws two sets of ever-decreasing
rectangles one in outline form and one filled alternately in black and white.
Exercise:
Unit 3
Introduction
Practical 11: Write a database application that uses any JDBC driver.
Practical 12: Develop a UI that performs the following SQL operations:1)
Insert 2)Delete 3)Update.
Practical 13: Write a program to present a set of choice for user to select a
product & display the price of product.
Exercise:
Unit 4
Introduction
Practical 14: Write a simple servlet program which maintains a counter for
the number of times it has been accessed since IT’S loading; initialize the
counter using deployment descriptor.
Practical 15: Create a form processing servlet which demonstrates use of
cookies.
Practical 16: Create a form processing servlet which demonstrates use of
sessions.
Unit 5
Introduction
Practical 17: WRITE a simple JSP program for user Registration & then
control will be transfer it into second page.
Practical 18 :Write a simple JSP program for user login form with static &
dynamic database.
Practical 19 :Write a JSP program to display the grade of a student by
accepting the marks of five subjects.

NTRODUCTION
What is an Applet?
According to Sun “An applet is a small program that is intended not to be run on its
own, but rather to be embedded inside another application….The Applet class provides a
standard interface between applets and their environment.”
Four definitions of applet:
A small application
A secure program that runs inside a web browser
A subclass of java.applet.Applet
An instance of a subclass of java.applet.Applet
The APPLET HTML Tag
Applets are embedded in web pages using the <APPLET> and </APPLET> tags. The
<APPLET> tag is similar to the <IMG> tag.
The CODE attribute of <APPLET> tag tells the browser where to look for the
compiled .class file. It is relative to the location of the source document.
The CODEBASE attribute is a URL that points at the directory where the .class
file is. The CODE attribute is the name of the .class file itself. For instance if
on the HTML page of the previous section you had written
The HEIGHT and WIDTH attributes specify how big a rectangle the browser
should set aside for the applet. These numbers are specified in pixels and are
required.
<APPLET
CODE=“TestApplet.class”
CODEBASE=“classes”
WIDTH=200 HEIGHT=200>
</APPLET>

then the browser would have tried to find TestApplet.class in the classes directory in
the same directory as the HTML page that included the applet. On the other hand if you
had written
<APPLET
CODE=” TestApplet.class”
CODEBASE=“http://www.foo.bar.com/classes”
WIDTH=200
HEIGHT=200>
</APPLET>
then the browser would try to retrieve the applet from http://www.foo.bar.com/classes/
TestApplet.class regardless of where the HTML page was.
In short the applet viewer will try to retrieve the applet from the URL given by the
formula (CODEBASE + “/” + code). Once this URL is formed all the usual rules about
relative and absolute URLs apply.
You can leave off the .class extension and just use the class name in the CODE
attribute. For example,
<APPLET CODE=“TestApplet”
CODEBASE=“http://www.foo.bar.com/classes”
WIDTH=200
HEIGHT=200>
</APPLET>
