Does anyone know how to accomplish this in Java?

I have tried null, "Null", etc. It seems that Java does not have a System.DBNull.Value like C# does.

How can I set the value of a field to null in my code?

I figured this out!

Turns out it had nothing to do with NULL. The problem was that the cursor was initialized as a SEARCH cursor but being used as an UPDATE cursor.

WRONG:
ICursor cur = Tab.Search(queryfilter, false);
row.set_Value(FIELD INDEX, WHAT GOES HERE?);   
cur.UpdateRow(row);

CORRECT:
ICursor cur = Tab.Update(queryfilter, false);
row.set_Value(FIELD INDEX, DBNull.Value);   
cur.UpdateRow(row);
