Introduction
In software development, the Integrated Development Environment (IDE) plays a pivotal role, serving as the cornerstone of productivity, efficiency, and code quality. Among all those available IDEs all over the internet, IntelliJ IDEA and Eclipse emerge as titans, each boasting a dedicated user base, extensive feature sets, and robust development ecosystems.
This article will explore the main differences between IntelliJ and Eclipse and help you decide which IDE is better for you. Let us start by introducing both IDEs.
An Integrated Development Environment (IDE) is a software application that provides comprehensive tools and features to facilitate software development tasks in one cohesive platform. It typically includes code editors, debuggers, compilers, build automation tools, and project management features, streamlining the development process and enhancing productivity for programmers and developers.
What is IntelliJ?
IntelliJ is a cross-platform Java IDE developed by JetBrains. It supports many programming languages like Java, Kotlin, Groovy, etc. It is known for its intelligent code completion, refactoring and debugging tools, and colossal plugin ecosystem. These plugins extend its functionality and help to integrate IntelliJ with various other tools. It is easy to use and provides a smooth experience for new developers.
JetBrains offer different editions of the IDE for various purposes:
Community Edition: This edition is free and open source. It is a popular choice for individual developers and minor projects. It provides all the basic features of an IDE, like code completion, debugging tools, etc.
Ultimate Edition: This edition is a commercial version of the IDE. It has all features of the Community Edition plus more. It supports more programming languages and has more productivity features. It is a popular choice for professional teams and large projects.
Educational Edition: This edition is for educational institutions, students and teachers. It allows a smooth learning process.
What is Eclipse?
Eclipse is a cross-platform open-source Java IDE developed by the Eclipse Foundation. It supports multiple programming languages like Java, C/C++, Ruby, etc., with the help of plugins. As it is an open-source project, it has better community support. It is better for experienced developers as it has many plugins that might confuse beginners. It requires fewer resources and performs better.
It is more customisable and offers two types of IDEs - Desktop IDEs and Cloud IDEs. Cloud IDEs like Eclipse Orion and Eclipse Che allow users to develop software wherever they go in their browsers.
Apart from the standard code completion, debugging, refactoring, testing and version control features, it offers additional features such as the following.
It offers Intelligent code analysis features that detect potential errors, unused variables, etc.
It provides code navigation features to quickly locate a class or a method within a large project.
It offers database integration by running queries, editing data etc., from within the IDE.
It supports Spring framework and JavaEE technologies.
It offers various tools for web development.
Features of Eclipse
Apart from the standard code completion, debugging, refactoring (not built-in, but available through plugins), testing and version control features, it offers additional features such as the following.
It offers intelligent code analysis that highlights errors in real-time and offers quick fixes.
It provides code navigation features to locate classes and methods quickly and shows a hierarchical view of code structure.
It also offers database integration.
It has a large plugin ecosystem, which allows customisation and allows us to tailor the IDE to our requirements. These plugins also allow multiple programming language support.
Which IDE is better for beginners?
For beginners, IDEs with user-friendly interfaces, extensive documentation, and robust community support are ideal. IntelliJ IDEA and Eclipse are both popular choices, but many beginners find IntelliJ IDEA more intuitive and beginner-friendly due to its sleek design, helpful features, and built-in support for various programming languages and frameworks. Ultimately, the "better" IDE depends on individual preferences, project requirements, and learning goals.
Frequently Asked Questions
Is IntelliJ really better than Eclipse?
For many developers, IntelliJ IDEA is preferred over Eclipse due to its intuitive interface, powerful features, and seamless integration with modern development workflows.
Which is better NetBeans or Eclipse or IntelliJ?
The choice between NetBeans, Eclipse, and IntelliJ depends on personal preference, project requirements, and familiarity with the IDE's features and ecosystem.
Is IntelliJ IDEA the best IDE?
IntelliJ IDEA is widely regarded as one of the best IDEs due to its extensive feature set, intelligent code assistance, and strong community support.
Can we open Eclipse projects with IntelliJ?
IntelliJ automatically detects Eclipse projects on a computer and thus allows opening them quickly.
Which IDE is easier to set up?
IntelliJ is easier to set up as it comes bundled with a JDK (Java Development Kit), whereas Eclipse needs us to download the JDK ourselves.
What is the difference between JDK and JRE?
JDK (Java Development Kit) is a software development package that includes tools for Java development like compilers and debuggers. JRE (Java Runtime Environment) is the runtime environment required to run Java applications.
