    public static void main(String args[])

loads dsn named empdsn
                        
                        //creates statement
			stmt=conn.createStatement();
                        
                        //to get records from database using
resultset
			rs=stmt.executeQuery("select * from emp");//for dis 1st
create emp named table 
                        System.out.println("EId        
Ename            DOB                        Dept       
Salary\n");
			while(rs.next())//moves cursor to the next record until
it reaches d last record
			{
                           
System.out.println(+rs.getInt(1)+"          
"+rs.getString(2)+"            "+rs.getString(3)+"        
"+rs.getString(4)+"         "+rs.getInt(5));
				
			}
			stmt.close();
			conn.close();
		}

		catch(Exception e)
		{
			e.printStackTrace();
		}
	}
}

Note:
-create emp table 1st wid attributes eid,ename,dob,dept,n   
 salary
-to add dsn(data source name)go to control   
 panel->Administrative Tools->Data Sources (ODBC) then one 
 small window will get opend..
-click on System DSN tab->Add->n select "Microsoft Access
Drive(*.mdb)"->finish->type Data Source Name(as i hv typed
in program "employeedsn" if u dnt want to change that dsn
which is written in d line
conn=DriverManager.getConnection("jdbc:odbc:employeedsn")

-you can give ne name tht u want instead of employeedsn...u
only need to provide d same name in Data Source Name

-next is no need to provide nethng for description
-then click on->select(to select database in *.mdb form)
   ---to select database table select drive on which u hv
saved ur database table n select that table by going to d
folder where u hv stored it by going to an appropriate directory
   ----if u select correct directory,table name will b
displyed in left hand side list box which then u need to
select n click on "OK" n again click on "OK"
    ----Your DSN will be displyed in System Data Sources List
---click on Ok n once you done this run the program
