delete multiple row using checkbox

We are providing you the code where we have specified only three fields bookid,author and title in the database.
1) Create book.jsp
<%@page import="java.sql.*"%>
<form name=myname method=post action="delete.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://localhost: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()){ %>
<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++;
}
}catch(SQLException e){ System.out.println(e.getMessage()); } %>
</table>
<input type="submit">
</form>
2) Create delete.jsp
<%@page import="java.sql.*"%>
<%String id[]= new String[10];
for(int i=0;i<10;i++){
id[i]=request.getParameter("check"+i);
out.println(id[i]);
}
%>
<%try{
Connection conn = null;
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mysql","root", "root");
ResultSet rs = null;
Statement st=null;
st=conn.createStatement();
for(int a=0;a<10;a++){
st.executeUpdate("delete from book where bookid='"+id[a]+"'");
}
}catch(SQLException e){
System.out.println(e.getMessage());
}
%>
