What Will I Learn?
  • apply the OOP principles in practice;
  • design their own OOP-based programmes;
  • operate with the basic concepts in programming - classes, objects, overloading and overriding, inheritance and many more;
  • understand the logic in multi-class projects and read the code with ease;

  • The IDE I am going to use is IntelliJ, you may opt for any other environment you are used to. Please, have it installed, as we are not starting from the installation process, but a step ahead.

Once we cover the idea of classes and objects, you are to be introduced to the basic OOP principles - encapsulation, inheritance, abstraction and polymorphism, The lectures are structured in a way to let you move in pace with the instructor, applying everything you have just seen by yourself. The logic of every piece of code is to be explained in details. Once the theoretical part cover, you'll complete 3 more projects, by yourself, as I'll be guiding you on the way. Nowadays, every programmer needs to be aware of what OOP is and how it is applied - so, why not making the first step now? 

Who is the target audience?
  • This course is for everyone who has basic knowledge of programming (what a variable is, what an if-statement is, how a loop works).
  • The language we are going to use is Java, but keep in mind this is a course about principles, not about syntax.
  • So, anyone, with any programming background is welcome.

I have been teaching for seven years now, always inspired by the enthusiasm of people, acquiring new knowledge. Keep It Super Simple - the basic principle to follow, every complex theory or concept turns out clear and easily applicable. Currently, I am a technical writer and an Android developer, aimed at creating educational software products. 

Before going into technology, however, I have been teaching English as a foreign language for more than 7 years. Teaching is what my passion remained - as people need to be explained, to be shown, to be helped to start speaking. I have been preparing students for the Cambridge FCE and CAE exams for more than 4 years. At the same time, my adult student have been on various levels - starting from the alphabet (A0) to being advanced (C1 level).
