What is IntelliJ?
IntelliJ IDEA is a computer program that helps people write code for software. It gives you tools, suggestions, and checks so you can create apps faster and with fewer mistakes.
Let's break it down
- Computer program: a set of instructions that runs on your computer.
- Helps people write code: it provides a special editor where you type programming language text.
- Tools: features like auto-completion, error highlighting, and debugging helpers.
- Suggestions: the IDE predicts what you might type next and offers fixes.
- Checks: it looks for mistakes while you type, so you can fix them right away.
- Create apps faster: because you spend less time searching for errors or writing repetitive code.
- Fewer mistakes: the built-in checks catch errors early, reducing bugs.
Why does it matter?
If you want to build software, a good development environment saves time, reduces frustration, and improves the quality of your code. IntelliJ makes learning to program smoother for beginners and boosts productivity for experienced developers.
Where is it used?
- Building Java desktop applications for businesses.
- Developing Android mobile apps using Kotlin or Java.
- Creating server-side services with Spring Boot or other Java frameworks.
- Writing plugins or extensions for other software, such as IDE add-ons.
Good things about it

Not-so-good things
- The full-featured Ultimate edition requires a paid license.
