Challenge: Factory Quality Control
Swipe to start coding
A factory receives multiple batches of parts, but some parts are defective and must be removed to identify high-quality components, which should be displayed without duplicates.
The PartBatch class represents a batch of parts, with a batch name (batchName) and a list of parts (parts). To access the list of parts from a batch, you use the getParts() method, and to retrieve the batch name, you use the getBatchName() method.
- Extract all parts from each batch using
flatMap()method. - Filter out defective parts by checking if the part name starts with
Defectiveusingfilter()method. - Remove duplicate parts to get a list of unique quality parts using
distinct()method.
