In Java, theArrayList.listIterator()returns aListIteratorthat iterates over the elements of the current list. AListIteratoris a bi-directional iterator that is fail-fast in nature. By default, elements returned by the list iterator are in proper sequence. 1.ArrayList.listIterator()Method Thelis...
In out case, to get the flattenedList, we need to iterate overStreamand merge consecutive lists into one for each successive nestedList. Note that due to extra instances ofArrayListcreated at runtime, this method does not give good performance for large nested lists. List<String>flatList=nested...
The Iterate.select returns a new collection with only the elements that evaluated to true for the specified predicate. SourceJava ArrayList - language reference In this article we have showed how to filter a list in Java. AuthorMy name is Jan Bodnar, and I am a passionate programmer with ...
In the above example, the iterator method of theListinterface is called. It performs simple iteration and checking — check if there is a next element to visit — and displays all elements in an Arraylist. Using the Java Iterator and ListIterator: import java.util.*; class CityNames { publ...

We’ll continue using our list of movies, but let’s pretend that we can only iterate over it using Java’s for each construct: for(String movie : IMDB_TOP_MOVIES) {// use movie value}Copy Here we need to use a separate variable to track the current index. We can construct that ou...
As Java developers, we often write code that iterates over a set of elements and performs an operation on each one. TheJava 8 streams libraryand itsforEachmethod allow us to write that code in a clean, declarative manner. While this is similar to loops,we are missing the equivalent of ...

Additionally, there is complexity not shown in this simple example. Aerospike does not natively support all of Java types. Mapping a java.util.Date to the database requires additional code to convert to an Aerospike representation and back for example. Sub-objects which also need to be stored ...
