I think you're using classes/interfaces wrongly... A class should describe a type (or singular/static instance) of object, an object an instance of that type, and an interface a type of class. Maybe a Hashtable<String, Hashtable<String, String>> would work like you want...

Code:

//initialize
Hashtable<String, Hashtable<String, String>> databaseQuery = new Hashtable<String, Hashtable<String, String>>();

//get a table's statements
Hashtable<String, String> statements = databaseQuery.get("tableName");

//get a specific type of statement for the table
String statement = statements.get("statementType");

Or you could do:

Code:

public class DatabaseQuery extends Hashtable<String, Hashtable<String, String>> {
    //implement special get and set methods if you like
}
