Here, the stream is sequential, meaning the combiner function doesn't have any effect (it is used only in parallel processing).
The supplier function, the first collect parameter, creates a StringBuilder instance with the initial value "c".
The accumulator, the second collect parameter, appends two elements and returns the built StringBuilder.
In the end, we got "cab".
