Here is your required code:

import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Servlet extends HttpServlet{ 
  public void doGet(HttpServletRequest request, 
  HttpServletResponse response)
  throws ServletException,IOException{
  response.setContentType("text/html");
  PrintWriter out = response.getWriter();
   response.setContentType("text/html");
   out.println("<form name=myname method=post action=edit.jsp><table border=1><tr><td></td><td><b><u>bookid</u></b></td><td><b><u>Author</u></b></td><td><b><u>title</u></b></td></tr>");
   try{

Connection conn = null;
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql://192.168.10.112:3306/mysql","root", "root");
ResultSet rs = null;
Statement st=null;
st=conn.createStatement();
rs = st.executeQuery("select * from book");
int i=0; 
while(rs.next()){
    out.println("<tr><td><input type=checkbox name=check"+i+" value="+rs.getString("bookid")+"></td><td>"+rs.getString("bookid")+"</td><td>"+rs.getString("author")+"</td><td>"+rs.getString("title")+"</td></tr>");
i++;
}
}
