courses belongs to a university such that the course selected would
be displayed.

b1.addActionListener(this);IT.addItemListener(this);CE.addItemListener(this);mech.addItemListener(this);EE.addItemListener(this);
EC.addItemListener(this); civil.addItemListener(this); } public
void actionPerformed(ActionEvent e) { if (e.getSource() == b1){
repaint();} } public void paint(Graphics g) { int i=10;int k=60;

of the list items would be displayed in text box.

PRACTICAL 2 (SWING)
3) Create a login form which contains user ID, password field
and two buttons submit and reset. If the user ID and password is
left blank on click of submit button, show a message to the user to
fill in the fields, on click of reset button clear the fields.

4) Create a split pane which divides the frame into two parts
.process a list and on selecting an item in a list the items should
be displayed in the other portion.

JList(texts);list.addListSelectionListener(this);description = new
JTextArea();JSplitPane innerPane= new
JSplitPane(JSplitPane.HORIZONTAL_SPLIT, list,
description);getContentPane().add(innerPane, "Center"); } public
void valueChanged(ListSelectionEvent event) { JList source =
(JList)event.getSource(); Display value =
(Display)source.getSelectedValue();
description.setText(value.getDescription()); } private JList list;
private JTextArea description; private Display[] texts = { new
Display("Text1", "This is text1."), new Display("Text2", "This is
text2."), new Display("Text3", "This is text3."), new
Display("Text4", "This is text4.") };}class Display{ public
Display(String n, String t){ name = n; des = t; } public String
toString() {return name; } public String getDescription() {return
des; } private String name; private String des;}
Output:

PRACTICAL 3 (JDBC)
5) Write a jdbc program to insert details of college student in
the ms Access database.
/* database connectivity with MS-Access is done by
creatingDataSourceName(dsn) in this example*//* Steps to use this
example: * go to ms-access and make a database called
"student_base" and createtable named student_base.mdb * 1.Go to
Control Panel 2.Click on Administrative Tools(windows 2000/xp),
Click onODBC(win98) OR if u have (windows 7) than go to
C:\Windows\SysWOW64\odbcad32.exe 3.click on ODBC 4.Then , you will
see a ODBC dialog box. Click on UserDSn 5.Click on Add Button
6.Select Microsoft Access Driver(*.mdb) driver and click on finish
7.Give a Data Source Name : student_base 8.Then Click on Select
9.Browse on the database addItemDB.mdb file on your disk by
downloading it link provided..will be stored 10.Click on OK.Once
the DSN is created, you can do this example*/

architecture) in Eclipse or Netbeans.

publicclass GetEmployeeAddressUsingStruct {publicstaticvoid
main(String s[]) throws Exception {Driver d= (Driver) (
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance());Properties

st=con.createStatement();ResultSet rs=st.executeQuery("select
permanent_address from personaldetails where empno="+s[0]);if
(rs.next()){System.out.println("Employee Found: Address");Struct
struct=(Struct)rs.getObject(1);Object
addr[]=struct.getAttributes();System.out.println("Flatno :
