Can`t close JDBC parameters.

Question

Hello, I am trying to close a connection of resultset and statement to a class called ConnectionFactory. In this class is method for accepting a close parameter and executing a close for it. I keep geting these type of error:
com/watts/db/GarmentDAO.java [75:1] cannot resolve symbol
symbol : method ConnectionFactory (java.sql.ResultSet)
location: interface java.sql.Connection
con.ConnectionFactory(result);
^
com/watts/db/GarmentDAO.java [77:1] cannot resolve symbol
symbol : method ConnectionFactory (java.sql.Statement)
location: interface java.sql.Connection
con.ConnectionFactory(statement);
^
com/watts/db/GarmentDAO.java [109:1] cannot resolve symbol
symbol : variable statement
location: class com.watts.db.GarmentDAO
if(statement != null)
^
com/watts/db/GarmentDAO.java [110:1] cannot resolve symbol
symbol : variable statement
location: class com.watts.db.GarmentDAO
statement.close();
I have imported all the Classes but where is the trouble.
Here is my code
package com.watts.db;
import com.watts.entity.Customer;
import com.watts.entity.Garment;
import com.watts.connections.*;

For the same reason declaring method and class variables final helps clarify your code, adding transient to business-tier class variables can also be helpful. Anyone using reflection to serialize an arbitrary class can "depend" on the keyword having connotative meaning.
You don't need to give your variables sensible names, but it costs almost nothing, so why not do it?
