    public class dbop {
        String url="jdbc:mysql://localhost:3306/youthsociety";
        String username="root";
        String password="";
        Connection con=null;
        Statement st=null;


        public void addmember(memberdata m){
            try{
                con=(Connection)DriverManager.getConnection(url,username,password);
                String query="INSERT INTO members VALUES(?,?,?,?,?,?,?,?)";
                st=(Statement)con.createStatement();
                st.executeUpdate(query);

            }catch(Exception e){

            }
        }

    }

st.executeUpdate(query) mark as wrong.

Answer

Ok, let me explain your problem.

1. You don’t have configured jdbc driver.
2. Don’t need to cast anything!
3. You have question mark ‘?’ In your query, and you are using simple Statement class to execute instead of PreparedStatement.

Now, if you are using simple Statement, follow this link: A Java MySQL INSERT example (using Statement)

If you are using PreparedStatement, you can follow this link: A Java MySQL INSERT example (using PreparedStatement)
