What is the Difference Between Intellij and Eclipse?

🆚 Go to Comparative Table 🆚

IntelliJ and Eclipse are both popular Integrated Development Environments (IDEs) for Java development, but they have some key differences:

  1. Licensing and Source: IntelliJ is a commercial product developed by JetBrains, while Eclipse is an open-source project.
  2. Out-of-the-box Features: IntelliJ offers more out-of-the-box features and is considered more beginner-friendly. Eclipse, on the other hand, requires the Java Development Kit (JDK) to be installed and supports Java only out-of-the-box. However, Eclipse supports more programming languages via plugins than IntelliJ.
  3. Performance: Eclipse handles large projects faster than IntelliJ, but IntelliJ works faster and smoother when working on existing projects.
  4. Usability: IntelliJ is considered easier to use and has a faster learning curve compared to Eclipse. Users have reported a more satisfying user experience in IntelliJ, with features like code completion, dropdowns, quick view, and project wizards being more intuitive.
  5. Debugging: IntelliJ is known to have a better debugger than Eclipse.
  6. Plugin and Extension Support: IntelliJ has better plugin and extension support than Eclipse.

In summary, IntelliJ is a more feature-rich and beginner-friendly IDE, while Eclipse is a more customizable and open-source option. IntelliJ is faster and smoother for existing projects, while Eclipse handles large projects better. Ultimately, the choice between the two depends on your specific needs and preferences.
