Requirements

  • A computer (Windows, macOS or Linux) where you can install the JDK and IntelliJ IDEA
  • No programming experience needed: the course starts from the very first program
  • About 4–6 hours a week for lessons and homework

Description

This course takes you from zero to a working backend developer, one small step at a time. Every lesson is an interactive page: you step through code like a debugger, try ideas in small labs and answer a checkpoint at the end of every part, so you know you understood before you move on.

Each lesson exists in Azerbaijani and English. Every code output and every quiz answer is checked by running it with JDK 25.

After each lesson you get homework in three levels, with the expected output for every task, so you can check your own work.
