To be effective developers, you need to master the programmer’s tools. This includes working with source control systems like Git, debugging skills, and mastering integrated development environments (IDEs) like IntelliJ IDEA or Eclipse. These tools help you increase your productivity and work more efficiently.

1.7. Practical Projects

Theoretical knowledge alone is not enough. To start a career as a Java Junior developer, you need to gain practical experience. Solving problems and participating in projects with real business tasks are crucial. This experience helps you apply what you have learned and prepare for the work environment.

Soft Skills
