SQL Select statement with PreparedStatement

import java.sql.*;

public class JdbcPreparedstatementExample {

       public static void main(String args[]) {
       String name="roseindia";
           try {
           Class.forName("com.mysql.jdbc.Driver");
           Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
           String sql ="select * from data where name=?";
           PreparedStatement pst = con.prepareStatement(sql);
           pst.setString(1, name);
           ResultSet rs = pst.executeQuery();
            while (rs.next()) {
                System.out.println(rs.getString("id"));
                System.out.println(rs.getString("name"));
            }

        } catch (Exception e) {
            System.out.println(e);
        }
    }
}
