Appendix B. Miscellaneous library updates
This appendix reviews the main additions to the Java 8 library.
The biggest update to the Collections API is the introduction of streams, which we discussed in chapters 4, 5, and 6. There are also other updates discussed in Chapter 9 and additional minor additions summarized in this appendix.
