Next up: an example based on the Map interfaceįor (Iterator> iterator = map.entrySet().iterator() iterator.The Collection in Java is a framework that provides an architecture to store and manipulate the group of objects. The manipulation operations are taken care of through accessing the key-value pairs. A Map stores data using the key-value pair format. The Map interface is inherited from Java Collection Interface. The Deque supports insertion and deletion operations on both sides of the Queue. The term DE-Que stands for Double-Ended Queue. ("Queue includes fruit 'Apple'? : " + ntains("Apple")) Ī Deque interface is inherited from the Java Collections Interface. The Queue is a linear Collection that offers data manipulation operations on the collection elements, and follows the FIFO(First In First Out) principle. For instance:Ī Queue interface is inherited from the Java Collections interface. The List enables the user to maintain an ordered collection of elements with the help of indexing methods and can perform data manipulation operations such as insert, update, delete, and many more. The List interface is derived from the java util package. ("last element of the set is: " + (Integer) sortedSet.last()) ("First element of the set is: " + (Integer) sortedSet.first()) Int count = įor (int i = 0 i sortedSet = new TreeSet(set) Here’s an example based on a set interface. The set interface is inherited from the Java collections Interface A Set interface cannot store duplicate/redundant elements in it. Well, after the quick briefing of all the data manipulating methods that can be used against Java Collections, the next step should be to dive into learning all the Interfaces and classes present in Java Collections with proper definitions and practical examples. Returns true is a particular value is presentĬreates splietarator over the elements in the collection The table below describes the methods available to use against Java Collections for data Manipulation Jobs. The following image depicts the Java Collections Hierarchy.Īfter the Hierarchy of Java collections you should also get to know the various methods applied to the Collections in Java to perform the data manipulation operations. Followed by the Java Collections Framework, you must learn and understand the Hierarchy of Java collections and various descendants or classes and interfaces involved in the Java Collections.Īlso Read: What is Java: A Beginners Guide To Java Java Collection Framework Hierarchy Java Collection Framework enables the user to perform various data manipulation operations like storing data, searching, sorting, insertion, deletion, and updating of data on the group of elements. Java Collection Framework offers the capability to Java Collection to represent a group of elements in classes and Interfaces.
