Description

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 The information which is shared there is very old and significantly out of date.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.

Probably you always dreamed about running your startup? In this course, you will be able to find the team who will teach you how to do that and (in particular cases) will be glad to help with implementation!

Hope you enjoy this course! And remember, we appreciate all your feedback! Your feedback will help us to become even better! Your feedback will help us to create to best Java course ever!

Five star content. The course is excellent but subtitles are a little messy, that's why I gave it a 4 star rating.

El contenido es bueno, te enseña materia avanzada de Java, el problema es si no sabes mucho inglés, los subtitulos son horribles, a veces te lian más de lo que te ayudan. A pesar de saber el idioma, me ha costado seguir bastantes partes de las lecciones. Aunque ponga pocas horas, creeme que te va a llevar muchisimas mas, sobretodo si haces los ejercicios, algunos son extensos y complicados. Aun así, buen curso y lo recomiendo para seguir avanzando en programación funcional.

An excellent break down of concepts for freshers as well as experience java devs to re-affirm knowledge of collections as its like.

There are good examples and explanations. As a 15-year-old, I can confirm that these are helpful... There are one-star ratings here, but I think that they are false. I get all of my udemy courses for free by getting coupon codes from websites like pastebin, etc... This course was among those that popped up, so I doubt that this course would really be hated... So far, this course is going well. Do you know what to do after this? What exact projects are possible to be built? What other course is there? Also, I heard that Vectors is a legacy class. Do we not use them because they're outdated? I'm just curious. Many people also say that these days, LinkedList is useless compared to ArrayList. What is your view on this topic?

Great course. It is well-structured and has a big amount of practice. I've got a lot of useful info from it. Thank you.

This course has better sides to it and worse sides too. The positive for me is to learn from a young mentor with fresh industry expertise which can be felt in examples and best-practice advice. The theory was explained in a decent way, but many times the slides provided were not enough and lacked "highlighting current text" to get along with the slide. The demos of examples were OK but could be better and more advanced. For example, reduce function example is lacking. The big home works are good, but I wish I could see the teacher solving it and explaining and not only the final solution. Also, personally, I need smaller exercises after each lesson, like small tasks and solutions, rather than big home works you don't always have the time to do

I LOVE YOU, you are the first person in my life who cleared in someway how to understand some java classes code even it is not so much clear for me, but I LOVE YOU AGAIN lot of thanks hope that you add more about how to understand java documentation just pick up any advanced classes and clear them It will be helpfull can you do this for me and notify me if you did lot of thanks for you clear explanation

The explanations are very clear and precise, I like the examples with real objects and also the practical exercises section!

I liked the structure: the lecturer starts from sourse investigation, then code and then examples how this code workes. Short and clear, no unnecessary information, no too long explanations when you forget where was the beginning. However, some things were not easy for understanding. It would be helpful if there were more grafic materials and very short description about kinds of problems that every method solves. Anyway I tried several courses on Udemy to understand Collections and Stream in practise and none of them was as helpful as this one.

Highly recommended course for those having intermediate knowledge about java Programming.The USP of this course is practical exercises ,they are very thoughtfully designed for the students to explore the topic in details. I found the tutor very helpful and always ready to clear doubts.
