6. Conclusion As we’re starting to see, the double colon operator – introduced in Java 8 – will be very useful in some scenarios, and especially in conjunction with Streams. It’s also quite important to have a look at functional interfaces for a better understanding of what happens behi...

A double colon, at most one of which may appear in any address, indicates multiple zero blocks. For example, FEDC:0000:0000:0000:00DC:0000:7076:0010 could be written more compactly as FEDC::DC:0:7076:10. In mixed networks of IPv6 and IPv4, the last four bytes of the IPv6 ...
(for example, owners, pets, specialties, and so on). However, we would like our corresponding entity names to be singular nouns (Owner, Pet, Specialty, so on). Conveniently, NetBeans allows us to modify the suggested JPA entity class names in this step by simply double-clicking the name...
