Add a method getListForQuery(String query) to the DatabaseManager class that will return a List of all the columns in the first row returned in the result set for the passed query. You can find out how many columns have been returned by getting a ResultSetMetaData object from the ResultSet object using the method getMetaData() method. You can then ask the ResultSetMetaData object for the number of columns by using the method getColumnCount().

What will be an ideal response?
