Start with the basic course, which covers the basics of syntax, data types, and logic. It is designed to gradually introduce you to the world of Java without overloading you with complex concepts. You will learn how to build simple programs and understand the structure of the code. This is a good start to move on to more complex topics.

All you need is a desire to learn and stable access to a device with a text editor. The courses cover examples that you can repeat yourself. There is no need for additional software at the start. Gradually, you will learn how to customize the working environment for yourself.

Each course is a separate level that logically continues the previous one. Topics are not duplicated, but develop: from basic principles to multithreading, working with APIs and network logic. This allows you to form a holistic understanding of the language. You will feel how the complexity and depth increase with each course.

The course topics cover Java syntax, conditional operators, arrays, collections, classes, objects, error handling, multithreading, and networking. You will learn to create structures, build program logic, and work with code on real-world examples. Over time, you will be able to implement full-fledged applications. The learning process is gradual, from simple to complex.

Yes, all courses contain practical tasks. They help to check how well the theory is learned. Tasks of different levels of complexity - from simple examples to project mini-tasks. This is a great opportunity to immediately apply knowledge in practice.

You can if you are already familiar with the basic concepts of Java. However, we recommend that you review the list of topics of previous courses to make sure that you do not miss important fundamental things. It is better to go through a few initial blocks for confidence. The sequence helps to avoid gaps in knowledge.
