import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;


public class DataPorting {
       public static void main(String[] args) throws Exception{ 
               Connection con = null;
                try {
                 Class.forName("org.apache.cassandra.cql.jdbc.CassandraDriver");
                 con = 
              DriverManager.getConnection("jdbc:cassandra://localhost:9042/ksfedemo");

                 String query = "SELECT * FROM customer  ";

                 Statement stmt = con.createStatement();
                 ResultSet result = stmt.executeQuery(query);

                 while (result.next()) {
                  System.out.println(result.getString("name"));
                  System.out.println(result.getString("email_id"));
                  System.out.println(result.getString("mobile_number"));
                 }

                } catch (ClassNotFoundException e) {
                 e.printStackTrace();
                } catch (SQLException e) {
                 e.printStackTrace();
                } finally {
                 if (con != null) {
                  try {
                   con.close();
                  } catch (SQLException e) {
                   e.printStackTrace();
                  }
                  con = null;
                 }
                }
