HashMapand HashSet. Java 1.5 included Concurrent implementations; for example ConcurrentHashMap and CopyOnWriteArrayList. Usually Collection classes are not thread-safe and their iterator is fail-fast. In this section, we will learn about commonly used collection classes...

The Java Collections Framework has been updated to support lambda expressions, streams, and aggregate operations. For more information on these topics, see the following pages: Performance Improvement for HashMaps with Key Collisions In rare situations, this change could introduce a change to the ite...
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. But these can also be overused and fall into some common pitfalls. To get a better understandi...
In this possible algorithm, we are going to show you how to apply a Collections.sort() method in a Java environment. With this algorithm, we will try to build some syntax and some Java codes to explain the problem statement further. ...
The Java Collections Framework is a collection of interfaces and classes, which helps in storing and processing the data efficiently. This framework has several useful classes which have tons of useful functions which makes a programmer task super easy.
