In this tutorial, you will learn about collection framework in Java. You will also be introduced to different interfaces in the Java collection framework. Learn to code solving problems and writing code with our hands-on Java course.

In this tutorial, we will learn about the Java Collection interface and its subinterfaces. The Collection interface is the root interface of the Java collections framework. Learn to code solving problems and writing code with our hands-on Java course.

Mar 21, 2025 · The Collection interface in Java is a core member of the Java Collections Framework located in the java.util package. It is one of the root interfaces of the Java Collection Hierarchy. The Collection interface is not directly implemented by any class.

Jun 22, 2024 · Here is a complete list of Java Collection programs for practice: Java Program to Get the Maximum Element From a Vector; Binary Search on Java Vector; Java Program to Get Elements of a LinkedList; LinkedList clear() Method in Java; Convert an Array into Collection in Java; Java Program to Change a Collection to an Array; Java Program to Compare ...

I have written several tutorials on Collections in Java. All the tutorials are shared with examples and source codes to help you understand better. Collections Framework hierarchy. 1. List. A List is an ordered Collection (sometimes called a sequence). Lists may contain duplicate elements.

In Java, the List interface is an ordered collection that allows us to store and access elements sequentially. It extends the Collection interface. Since List is an interface, we cannot create objects from it. In order to use the functionalities of the List interface, we can use these classes:

Mar 12, 2024 · Take a look at our Java Collection Exercise that contains Java Collection Practice Problems to practice and to develop your Java Programming skills. Our Java Collection Practice Exercise will cover all the topics from Basic to Advanced, from ArrayList to Priority Queue. So, let's dive in and sharpen our Java Collection skills together!

Aug 3, 2022 · 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.

All the operations that you perform on data such as searching, sorting, insertion, manipulation, deletion, etc. can be achieved by Java Collections. Collection Framework defines several classes and interfaces to represent a group of objects as a single unit. Collections are used to store, retrieve, manipulate, and communicate aggregate data.
