Hi Friend,
We are providing you a simple application.
Create table test(ques,op1,op2,op3,op4,ans) and answers(id,ans). Then try the following code:
1)form.jsp:
<%@page import="java.sql.*"%>
<html>
<form method="post" action="result.jsp">
<table>
<%
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/register","root";, "root");
Statement st=connection.createStatement();
ResultSet rs=st.executeQuery("Select * from test");
int i=1;
while(rs.next()){
%>
<tr><td><%=i%></td><td><%=rs.getString("ques")%></td><td><input type="radio" value="<%=rs.getString("op1")%>" name="radio<%=i%>"/><%=rs.getString("op1")%></td><td><input type="radio" value="<%=rs.getString("op2")%>" name="radio<%=i%>"/><%=rs.getString("op2")%></td><td><input type="radio" value="<%=rs.getString("op3")%>" name="radio<%=i%>"/><%=rs.getString("op3")%></td><td><input type="radio" value="<%=rs.getString("op4")%>" name="radio<%=i%>"/><%=rs.getString("op4")%></td></tr>
<%
i++;
}
%>
<tr><td><input type="submit" value="submit"></td></tr>
</table>
</form>
</html>
2)result.jsp:
result.jsp:
<%@page import="java.sql.*"%>
<%
String st[]=new String[10];
for(int i=0;i<st.length;i++){
int j=i+1;
st[i]=request.getParameter("radio"+j);
System.out.println(st[i]);
}
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/register","root";, "root");
Statement stmt=connection.createStatement();
ResultSet rs=stmt.executeQuery("Select ans from answers");
String ans="";
while(rs.next()){
ans+=rs.getString("ans")+" ";
}
int count=0;
String answers[]=ans.split(" ");
for(int i=0;i<answers.length;i++){
if(st[i].equals(answers[i])){
count++;
}
}
out.println("Your "+count+" answers are correct");
%>
