Hi Friend,

We have taken student_id=1.According to this id, we are retrieving the data.


package form;
import java.sql.*;
import java.util.*;

public class DBOperation
List dataList = new ArrayList();
Connection con;

public void connect() throws Exception{
try {
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root";);
catch (ClassNotFoundException e) {
public List getExamInfo()

Statement stmt = con.createStatement();
String query="select subject,marks,exam_date,exam_timing,exam_controller,exam_conducted_by,exam_supervision_by,percentage,remarks,exam_type from exam where student_id=1";
ResultSet rs=stmt.executeQuery(query);

catch(Exception e)
return dataList;
