Hi Friend,

Create a table ans(ques,op1,op2,op3,op4,op5,ans) in the mysql database and try the following code:

1)radio.jsp:

<[email protected] import="java.sql.*"%>
<form name="form" method="post" action="result.jsp">
<table>
<%
Class.forName("com.mysql.jdbc.Driver");
Connection conn =DriverManager.getConnection("jdbc:mysql://localhost:3306/register","root","root";);
Statement st=conn.createStatement();
ResultSet rs=st.executeQuery("select * from answers");
int i=0;
while(rs.next()){
%>
<tr>
<td><%=rs.getString(1)%></td>
<td><input type="radio" name="radio<%=i%>" value="<%= rs.getString(2) %>"></td><td><%=rs.getString(2)%></td>
<td><input type="radio" name="radio<%=i%>" value="<%= rs.getString(3) %>"></td><td><%=rs.getString(3)%></td>
<td><input type="radio" name="radio<%=i%>" value="<%= rs.getString(4) %>"></td><td><%=rs.getString(4)%></td>
<td><input type="radio" name="radio<%=i%>" value="<%= rs.getString(5) %>"></td><td><%=rs.getString(5)%></td>
<td><input type="radio" name="radio<%=i%>" value="<%= rs.getString(6) %>"></td><td><%=rs.getString(6)%></td>
<td><input type="hidden" name="ans<%=i%>" value="<%= rs.getString(7) %>"></td>

</tr><%
i++;
}
%>
<tr><td><INPUT type="submit" name="submit" value="Submit"></td></tr>
</table>
</form>

2) result.jsp:

<[email protected] import="java.sql.*"%>
<[email protected] import="java.util.*"%>
<%
String id[]= new String[10];
for(int i=0;i<10;i++){
id[i]=request.getParameter("radio"+i);
}
String str[]= new String[10];
for(int j=0;j<10;j++){
str[j]=request.getParameter("ans"+j);
}
boolean isCorrect = Arrays.equals(id,str);
out.println("Your Answers are : " + isCorrect);
%>

Thanks
