7 Best Courses to Learn Java Collections Framework and Stream API in 2024
My favorite online courses to learn Java Collections and Stream API in 2024 from Udemy, Coursera, Pluralsight, and Educative.
Hello guys, if you want to learn Java Collections and Stream API and looking for the best Collections and Stream Java courses then you have come to the right place. Earlier, I have shared the best Java Courses for beginners, and today, I am going to share the best courses to learn Collections and Stream, two of the most important API from JDK,
If you have been programming in Java, then you know that Collections and Streams are two of the most important Java APIs. There is hardly any Java program I have written in my 15 years of professional Java development career where I have not used any classes from Collections and recently from Stream API.
I strongly believe that every Java developer should have a good knowledge of both of them, and that’s why I am writing this post. If you are new to Java, then you might be thinking about why they are so important?
Well, they are important becuase they deal with data, and data is at the heart of every application and business. For example, if you create an application like Facebook, then where do you store your Users on memory?
Most likely, you will store them on a List or Hash table, and they are the classes that are provided by Java Collection Framework. In fact, the choice of List vs. Hashtable can also make a difference in how you will search for your users, and that’s why a solid knowledge of Java Collections and Streams is important.
In other words, the Java Collection framework also provides implementations of popular data structures like an array, linked list, hash table, tree, stack, queue, priority queue, etc. in the Java programming language.
Streams are relatively new and provide a way to extract data from collection and perform common operations like filtering, transformation, aggregation, normalization, and much more.
Good knowledge of both Java collections and Stream goes a long way in writing better Java code, which is the objective of every Java developer and imperative for anyone who wants to become an expert Java developer.
If you are looking to improve your knowledge of the Java Collection framework and Stream API and looking for some excellent resources, then stay on. In this article, I am going to share the best online courses to learn Java Collections and Stream API in depth.
Btw, if you are new to Java and looking for a single course that covers everything a Java developer needs to know then I suggest you check out The Complete Java MasterClass course on Udmey. It is also one of the most up-to-date courses and covers new features like var, static factory method for collections, and Java modules from recent Java releases.
7 Best Courses to learn Java Collections and Stream API in depth
Without wasting any more of your time, here is my list of best online courses to learn Java Collections and Stream API from scratch and master them for writing better Java code:
1. Java Fundamentals: Collections By Richard Warburton
This is a slightly old course but still, one of the best cours to learn Java Fundamentals like List, Set, Map, Queue, Stack, etc. Created by a Java champion and popular instructor Richard Warburton, this course is packed with some of the most useful information for Java developers.
The course starts with why you really need to use collections instead of arrays, covers the capabilities of Lists, Sets, and Maps, and explains the different data structure tradeoffs.
Since working with data is fundamental to any business problem and Java Collections are data structures designed to store, and process data in memory, a good knowledge of Collections is imperative, and if you want to start with basics first, then this is the right course you.

Though you need a Pluralsight membership to access this course but don’t worry, Pluralsight has made all of their 7000+ courses free for one month. You can take advantage of fo that and can learn Collections.
If you can, I also encourage you to join Pluralsight becuase you will gain access to 7000+ expert-led courses on the latest technologies which are essential for programmers who need to keep themselves up to date. You can also use their 10-day-free-trial to watch this course for FREE.
2. From Collections to Streams in Java 8 Using Lambda Expressions
This is another course on Pluralsight by another Java Champion, Jose Paumard who creates in-depth Java courses on Pluralsight. I first come across Jose Paumard while attending his Multithreading course, which is also a great one.
Didn’t I said that Pluralsight has expert-led courses and their Java courses are a great example of that as most of them are designed and created by Java Champions like Jose and Richard Warburton.
As the title suggests, this course is focused on a new way of coding in Java and it will introduce you to the new patterns from Java 8, based on lambda expressions, the functional interfaces, the Collection Framework, and the Stream API.

You will not only learn about lambda expressions but also about new patterns to process large data in Java without that Lambda would not be that useful. These new patterns have been added to the Collection Framework, and to the new Stream API.
This course also explains key functional programming concepts like map, filter, and collect like what they are and why it has been added to the Stream API. Ultimately you will learn new ways to efficiently process bulk data in Java and improve your parallel programming skills.
3. Introduction to Collections & Generics in Java
This course provides a simple guide to understand generics, basic collections, and reflection in Java! It creates by Holczer Balazs and the course is trusted by more than 12K students in Udemy.
In this course, you will learn the basic concepts and functions that you will need to build fully functional programs with the Java programming language.
You will also learn the basics of generic types, generic methods, type parameters, and the theoretical background concerning these topics. This is a fundamental part of Java so it is definitely worth learning.

4. Java Streams API Developer Guide
Nelson Djalo is one of the most underrated Java instructors on Udemy. I have attended a couple of his courses like this one and Spring Boot essentials and I have been really impressed with his way of teaching and clear-cut explanation with working code in the background.
This course is completely focused on Java Stream API and you will learn all essential concepts and methods a Java developer needs to know like the map, reduce, flatmap, filter, groupBy, and others.
Nelson not only explains what does a particular method does but also shows the code about how to use that method in a bigger scheme of things. If you need a hands-on course to learn Java Streams then I highly recommend you check out this course.
