In Java 8, this can be shortened to the following: 1list.sort(Comparator.comparing(Person::getLastName)2.thenComparing(Person::getFirstName)); This example uses a static method on an interface (comparing) and a default method (thenComparing) which are discussed in the next chapter. ...

5. Conclusion This Java tutorial explored various ways to create immutable and unmodifiable maps. It is recommended to use the solution available in the latest Java version we are using. Happy Learning !!
For example, it is not generally permissibleforone thread to modify a Collectionwhileanother thread is iterating over it. In general, the results of the iteration are undefined under these circumstances. Some Iteratorimplementations(including those of all the general purpose collection implementations pr...
// in addition to sequential traversal, by supporting decomposition as well as single-element iteration. // In addition, the protocol for accessing elements via a Spliterator is designed to impose // smaller per-element overhead than {@code Iterator}, and to avoid the inherent ...
