JAVA CERTIFICATION QUESTION: Stream collect and StringBuilder

· java,ocp

Given:

What is the output?

  • A. abc
  • B. acb
  • C. bac
  • D. bca
  • E. cab
  • F. cba
  • G. cacb
  • H. cbca

#java #certificationquestion #ocp

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".
