Java Collections Framework + Generics, Lambdas & Stream API
- Description

- Reviews
From this course, you can learn Java Collections Framework, together with Generics, Lambda Functions, Method References, and Stream API.
There are a lot of other courses on this topic. So, why would you choose exactly this course? Here are just a few reasons:
– Coding examples
To learn to program is not enough just watching videos and reading books. You also need to have a lot of practice. In this training course, you will review multiple practical tasks and coding examples which will help you learn and understand Java better.
– Open source code
We hide nothing from our students! Including the source code for the home task solutions and source code of examples that were shared during the lesson. Having the source code you can just copy and paste it to run it on your local computer to understand how things work better.
You are allowed to use all source code examples for learning purposes. This helps significantly to configure the environment and make tests work, especially in case students didn’t work with any testing framework in the past.
– Q&A support
The significant difference between the online and offline learning process is the instructor’s availability. If you are in one room with a tutor he always can help you to get understand the specific concept or to help fix your code on your computer.
In this course, we are supporting students with answers to any questions flagged in the Q&A section. In case there will be recurring questions – separate video lessons will be created to show how to address the issue.
So with this course you are not just getting video materials, code exercises, source code, access to the free mobile application without limits (which is still pretty cool, huh? 🙂 ), but you also get tutor support and answers to your questions along with this course.
– Relevant knowledge
After our team investigated other Java courses on Udemy we realized that most of them have nothing in common with real life. The information which is shared there is very old and significantly out of date. For example, the instructor teaches a framework which is not been used already for 15 years. Or instructors do stress on the programming design which is not used anymore at all!
The instructor of this course is a consultant in a top-rated IT outsourcing company and helps to bring cutting-edge solutions in IT for all his clients. Feel free to check the LinkedIn page of the instructor and check skills endorsement. More than 19 thousand people across all over the world (BTW most of them are from the top 100 companies of the world) evaluated the skills of Andrii Piatakha.
With this course, you can be sure that you will spend your time learning the right things from one of the best IT consultants in the world.
– Free mobile App without limits for our students
Knowing Java is one skill. Be able to pass interviews in the company – that is another skill 🙂 Nowadays a lot of companies use tests to select candidates on the first level of interview. We developed applications to practice skills specifically for such purposes.
In this course, we will provide you link to download our FREE mobile app for android. (soon it will be also available for iOS platforms)
The instructor of this course comes up with hundreds of tests that are used to test the knowledge of candidates. With this application, you will be well-prepared for the interview.
Also, only for our students – there is no limit on attempts to pass certification. In the course, we will tell you how to set up a special bonus code that will remove restrictions for our students inside the app.
– High concentration of useful material in each lesson
Sometimes you can notice that watching 5 minutes of our lesson is equivalent to watching another 30 minutes lesson.
This is because time spent for preparation for the lesson (script for the lesson, lesson structure) and video editing (to cut boring pieces of the lesson or time when the program loads) sometimes 10 times as much (sometimes even 20) as the final lesson duration after video editing.
Also, each topic is separated from another. In case some concept will be explained in the next lesson and you don’t need to worry about understanding this in the scope of this lesson – the instructor will make an announcement when a specific topic will be covered.
Go and try it yourself! We will appreciate your feedback.
