Java Collection Implementing Arraylist Part 3 Youtube
Java collections are the one stop solutions for all the data manipulation jobs such as storing data, searching, sorting, insertion, deletion, and updating of data. java collection responds as a single object, and a java collection framework provides various interfaces and classes. we will learn them through the following docket:. Java collections framework provides implementation classes for core collection interfaces. we can use them to create different types of collections in the java program. some important collection classes are arraylist, linkedlist, hashmap, treemap, hashset, and treeset. Collection interface. iterator interface. the collection in java is a framework that provides an architecture to store and manipulate the group of objects. java collections can achieve all the operations that you perform on a data such as searching, sorting, insertion, manipulation, and deletion. java collection means a single unit of objects. The collection interface (java.util.collection) and map interface (java.util.map) are the two main “root” interfaces of java collection classes. what is a framework? a framework is a set of classes and interfaces which provide a ready made architecture. in order to implement a new feature or a class, there is no need to define a framework. The java collections framework provides various data structures and algorithms that can be used directly. this has two main advantages: we do not have to write code to implement these data structures and algorithms manually. our code will be much more efficient as the collections framework is highly optimized.

The collections classes implement these interfaces and provide concrete functionalities. java collections hierarchy 1.1. collection. collection interface is at the root of the hierarchy. collection interface provides all general purpose methods which all collections classes must support (or throw unsupportedoperationexception). Problem description. how to use different types of collections ? solution. following example uses different types of collection classes and adds an element in those collections. The jdk immutable collections are not contractually immutable, because they implement the mutable list, set, map interfaces. google guava guava has collection types that are structurally immutable.
