Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
By using this iterator object, you can access each element in the collection, one element at a time. importjava.util.Iterator;importjava.util.LinkedList;//fromjava2s.compublicclassMain{publicstaticvoidmain(String args[]) { LinkedList<String> ll =newLinkedList<String>(); ll.add("A"); ll....
Interfaces:The abstract data types are referred to as interfaces in Java. They allow Java collections to be manipulated in a way that is not tied to the specifics of their representation. The Set represents the sorted collection of elements. In addition, object-oriented programming languages form...
Inheritance in Java or OOPS (Object-oriented programming) is a feature that allows coding reusability.In other words,Inheritance self-implies inheriting or we can say acquiring something from others. Along withAbstraction,Encapsulation, andPolymorphism,Inheritanceforms the backbone of Object-oriented progr...
That's all about thedifference between a fail-safe and a fail-fast Iterator in Java. Now you know that it's just two kinds of iterator that behave differently when the underlying collection class is modified by adding or removing any object. ...
Many problems solved with the Iterator pattern are now solved much more efficiently with the patterns brought by the Stream API. But Java 8 is not only about lambdas, streams and collectors, there is also a new Java Date and Time API which are covered in this course. This API fixes all ...
LinkedList(Collection C): Used to create a ordered list which contains all the elements of a specified collection, as returned by the collection’s iterator. 1 Sep, 2019 17 Java LinkedList Java LinkedList is linear Java data structures where all the elements are stored in non-contiguous ...
Iterator Pattern Mediator Pattern Observer Pattern Strategy Pattern Template Pattern Visitor Pattern Null Object Pattern Understanding Design Patterns in Java Different creative, structural, and behavioral ways exist to design patterns to provide solutions to instantiate an object in the best possible way fo...

Fail Fast vs Fail Safe Iterator in Java By: Rajesh P.S.When multiple threads are concurrently iterating over a collection, if one of the threads alters the structure of the collection during the iteration process, it is referred to as Concurrent Modification. This occurrence triggers the ...
