Quick Answer
Handle nulls in streams: filter() with Objects::nonNull to remove nulls before processing. Optional.ofNullable() to wrap potentially null values. map() handles nulls poorly - returns a stream with null elements that blow up on later operations. For map values: use getOrDefault() or computeIfAbsent(). Consider using Optional upstream to avoid nulls entering the stream at all.
