Object Oriented Programming Basics to Advance Java OOP


Knowing any programming language basics
Understanding Java syntax


From this course, you can learn Object-Oriented Programming from basics to advanced concepts. All code examples in the course are written in Java but that’s doesn’t mean you can’t apply the knowledge from this course in other programming languages. You can easily use the knowledge from this course in any language if you want to build applications with the help of an object-oriented programming approach. 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 exercises 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 have different practical tasks which will help you learn and understand Java better. One of the key tasks where you can practice your knowledge is the implementation of a backend system for an online store. Also, you have a lot of tasks that use domain-specific terminology: accounts, transactions, users, carts, menu, services, etc. So that means you are learning programming without abstract concepts like it is written in the books or in other courses. You learn domain-specific terminology and during the lessons, we investigate specific extracts from code that can give you a clear vision of how you can apply the knowledge in real life.- Open source codeWe 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 knowledgeAfter 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 studentsKnowing 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 lessonSometimes 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.So don’t wait! Take a look at the lessons’ preview if you still have doubts! Buy this course today, and you will get all updates for FREE! For those who successfully passed this training course, or for students who were recognized for asking amazing questions, there is a special offer from the IT-Bulls company! The creator of this course is IT-Bulls company CEO and Founder. We are always in search of talents to run our amazing startups together with you. 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! See you at the lessons! 🙂
