Learning Kotlin programming from scratch

Today is the first day of your new life

You’re reading these lines — and that’s already the first step toward change. Many of our graduates felt at the beginning that programming was too complicated, that they should have started earlier 🕒, and that it’s hard to combine learning with work and family👶. But despite all doubts, they tried — and they made it.

There’s no “right” age or “perfect” past experience here. The main thing is your desire to learn and change 💪. Thousands of people before you started from very different points: from teachers to engineers, from moms on maternity leave to economists. All of them once doubted — but now they’re building a new career, earning more, and living more freely 💸.

If you have doubts right now — that’s normal. Everyone who read this lecture had them. But you’re not alone here. We’ll help you go through this path step by step, and you’ll see for yourself that life is wonderful 🎯.

JavaRush is not just a course, but a huge community of more than a million people 🌍. Every day someone solves a task here, gets support, finds a mentor, or makes a new friend. Success here is not an accident, but the result of teamwork and mutual support!

Kotlin — a modern next-generation language

Kotlin is a programming language created by JetBrains and officially supported by Google. It’s not an experimental tool, but a very powerful programming language used to build real products that millions of people use every day 🚀.

Kotlin combines simplicity and power. It lets you write code that’s shorter, clearer, and safer than many older languages. That’s why more and more companies choose Kotlin for new projects.

Most importantly, Kotlin is designed to be convenient for the developer. It helps avoid common mistakes, speeds up development, and makes the learning process more enjoyable.

Where Kotlin is used

📱 Mobile apps (Android):
Kotlin is the official language for Android development. Most new Android apps are written in Kotlin. By mastering it, you’ll be able to create apps that thousands and millions of people will use.

🌐 Web development:
Kotlin is used to build the server side of web applications. It’s used to create APIs, web services, and complex backend systems. Many modern startups and companies choose Kotlin for their servers.

💻 Desktop programs:
Kotlin makes it possible to create programs for Windows, macOS, and Linux. You’ll be able to write real applications that run on users’ computers.

☁️ Cloud services:
Kotlin is used in cloud platforms and server systems. It’s well-suited for building scalable and reliable solutions.

🔬 Automation, tools, and internal systems:
Companies use Kotlin to build internal tools, automate processes, and process data.

Why Kotlin is a great choice to start with

Kotlin was created with decades of development experience in mind. It removes many of the complexities of older languages and lets you focus on the program’s logic rather than technical details.

Kotlin code:

• is easier to read
• is easier to write
• is harder to break by accident
• is learned faster by beginners

This means you’ll see the results of your work faster — and that’s very important for motivation.

What you’ll achieve soon

As early as today, you’ll write your first real Kotlin program 🏆. In 3 months, you’ll master the tools used in real companies and build your first mini-projects. After completing the course, you’ll be able to apply for a Junior Kotlin Developer position. You’ll gain not only new knowledge, but also confidence: “I did it. I can change” 🏆.

2026 is an ideal time to start in IT, because demand for mature specialists with real life experience is only growing 📈. And your age is your strength 💪, not a weakness.

Most of our graduates had doubts at the start. But now they say: “I’m glad I didn’t back down then.” You’re next. Trust yourself, take the first step, and then we’ll go together 🤝. Start learning and you’ll see: it really changes your life! 🚀
