What is a Spliterator?

Like Iterator and ListIterator, Spliterator is a Java Iterator, which is used to iterate elements one-by-one from a List implemented object. Some important points about Java Spliterator are: It uses tryAdvance() method to iterate elements individually in multiple Threads to support Parallel Processing.Click to see full answer. Then, what are the differences between iterator and Spliterator in Java 8?Main differences between Iterator and Spliterator are as follows: Spliterator can be used with Streams in Java 8. Iterator uses External Iteration to iterate Collections. Spliterator can iterate Streams in Parallel as well as Sequential manner. what is iterator in Java? In Java, Iterator is an interface available in Collection framework in java. util package. It is a Java Cursor used to iterate a collection of objects. It is used to traverse a collection object elements one by one. It is available since Java 1.2 Collection Framework. Similarly, you may ask, is there an iterator to allow programmer to traverse in forward/backward direction? In Java, ListIterator is an interface in Collection API. It extends Iterator interface. To support Forward and Backward Direction iteration and CRUD operations, it has the following methods. We can use this Iterator for all List implemented classes like ArrayList, CopyOnWriteArrayList, LinkedList, Stack, Vector, etc.What are streams in Java 8?Stream In Java. Introduced in Java 8, the Stream API is used to process collections of objects. A stream is a sequence of objects that supports various methods which can be pipelined to produce the desired result. A stream is not a data structure instead it takes input from the Collections, Arrays or I/O channels.
