Sorting NULL fields on Visualforce Page using Comparable Interface

Hello, 

I have implemented Custom Sorting on a VF page using Comparable Interface. If there are 10 records in a Page and few of the fields on the records are NULL then the List.Sort method is not functioning properly when there are NULL and NOT NULL fields included. Please suggest. 
 

Thanks

Hi , 


if (SortDirection == 'Ascending')
            // Check if account type is not Null, if its Null return -1
            return this.account.Type != Null ? this.account.Type.compareTo(otherType) : -1;
        // For Descending
        else
            // Check if account type is not Null, if its Null return 1
            return this.account.Type != Null ? otherType.compareTo(this.account.Type) :  1;

Or 

Integer otherVoteNum = other != null ?
