Difference Between Eclipse and IntelliJ IDE

IDE is an acronym used for an integrated development environment. It is a product suite that combines essential devices that are required to compose and test various programming requirements such as code, software, etc. Designers utilize various devices all throughout the process of programming code creation, building, and testing. Improvement devices frequently incorporate word processors, code libraries, compilers, and test stages. Without an IDE, a designer must choose, send, coordinate, and deal with these instruments independently. An IDE brings a large number of those advancement related instruments together as a solitary system, application or administration. The integrated toolset is intended to improve programming advancement and can recognize and limit coding mix-ups and errors. Some IDEs are open source, while others are business contributions. An IDE can be an independent application or it very well maybe a piece of a bigger bundle.

Selecting the most appropriate IDE can make you or break you as a coder in your career. Most designers would be lost without the solace of their favored IDE, which deals with classpath, making documents, direction line contentions, and so forth. Today we shall discuss the two most famous IDEs that are used all across the horizons of the IT world. We shall try to differentiate between IntelliJ and Eclipse. The war between the two is never-ending. Some coders believe IntelliJ is better and some find their solace in Eclipse. We will demonstrate the differences between the two and then you can decide for yourself.

Introduction of Eclipse IDE

With regards to processing, Eclipse is an IDE that is used widely for creating applications utilizing the Java programming language and other programming dialects, for example, C/C++, Python, PERL, Ruby and so forth.

The Eclipse stage which gives the establishment to the Eclipse IDE is made out of modules and is intended to be extensible utilizing extra modules. Created utilizing Java, the Eclipse stage can be utilized to create rich customer applications, incorporated advancement situations, and different devices. Obscuration can be utilized as an IDE for any programming language for which a module is accessible.

The Java Development Tools (JDT) venture gives a module that enables Eclipse to be utilized as a Java IDE, PyDev is a module that enables Eclipse to be utilized as a Python IDE, C/C++ Development Tools (CDT) is a module that enables Eclipse to be utilized for creating application utilizing C/C++, the Eclipse Scala module enables Eclipse to be utilized an IDE to create Scala applications and PHPeclipse is a module to overshadow that gives total improvement device to PHP. 

Introduction of IntelliJ IDE

IntelliJ IDE is an extraordinary programming condition or coordinated improvement condition (IDE) to a great extent implied for Java environments. This condition is utilized particularly for the advancement of projects. It is created by an organization called JetBrains, which was officially called IntelliJ. It is accessible in two versions: the Community Edition which is authorized by Apache 2.0 and a business release known as the Ultimate Edition. The two can be utilized for making programming which can be sold. What makes IntelliJ IDE so not the same as its partners are its convenience, adaptability and its strong plan.

IntelliJ IDE was created by JetBrains, once in the past known as IntelliJ. It was first discharged in 2001, and it flaunted highlights like propelled code route and the capacity to refactor codes, which made it exceptionally prominent. It even got the qualification of being cast a ballot the best programming apparatus dependent on Java in 2010, sidelining built up devices like NetBeans, Eclipse, and JDeveloper. The open-source improvement condition for Android discharged by Google in 2014 is additionally founded on IntelliJ IDE. The IDE underpins numerous other programming dialects, for example, Python, Lua, and Scala.

The most compelling motivation it is viewed as outstanding amongst other programming devices dependent on Java is its help highlights, which makes it simple to utilize and makes the projects made by it all around planned. It additionally has propelled blunder checking highlights which permits quicker and simpler error detection.

Difference Between Eclipse & IntelliJ 

1). Multiple projects

This is an Eclipse champ without a doubt. It can open numerous tasks in a similar window, giving the coder authority over conditions and relations. Intellij has an alternative to open one anticipate with different modules, yet we observed it is bulky and in times somewhat carriage. If you are going to utilize plenty of undertakings together and hate to switch windows, then Eclipse should be your go-to IDE.

2). Code completion & inspection

While Eclipse can include modules, for example, check style, this one unquestionably goes for Intellij. The default code fruition and help with Intellij are quicker and better. On the off chance that you are a newbie engineer, Intellij can improve your code.

3). Performance

The more modules are introduced on the IDE, the more substantial it is for your PC. Nonetheless, saying that Eclipse handles enormous ventures quicker. Also, both of the IDE's is by all accounts RAM addicts. Ventures normally open quicker in Eclipse, as Intellij files the whole venture on startup, however, while taking a shot at a current task, Intellij works smoother. For instance, we have an enormous SOAP venture, which is difficult to deal with Intellij, so a few of us even learn Eclipse only for that.

4). Repository integration

Both of the IDE's have SVN\GIT\etc modules. Presumably, Intellij's module is progressively solid, has better GUI and simpler to utilize.

5). GUI builder

We found that the implicit Intellij GUI manufacturer is progressively agreeable, and as referenced above, convenience shrewd its simpler to learn, and increasingly charming to create.

6). Software License

IntelliJ IDE Community Edition is the open center, instead of open source, and is secured by the Apache 2.0 permit. While this implies you can utilize the IDE uninhibitedly for a venture, it likewise ponders the module environment as the permit does to some degree limit the improvement of modules and expansions. Be that as it may, as a business venture, IntelliJ IDE has the benefits of a company with a spending limit behind it, as opposed to a network-driven non-profit.

Eclipse IDE is completely open-source under the Eclipse Public License (EPL) v2, and the code is kept up by a non-benefit – The Eclipse Foundation. While having almost no suggestions on the improvement experience, the open-source permit of the IDE considers an increasingly broad module biological system and makes open source supporters feel warm inside realizing they use programming created by the IT network for the IT network.

7). System Requirements

IntelliJ IDE can be introduced on Windows, macOS, and Linux with the accompanying equipment:

  • You need at least 2 GB RAM however 4 GB RAM is what is recommended
  • The next requirement is 1.5 GB of free hard disk space along with at least 1 GB RAM specially allocated for caches
  • A minimum screen resolution of 1024×768
  • Eclipse IDE can run on anything that supports JVM including Windows, macOS, Linux, and Solaris. The hardware it demands is very basic:
  • Eclipse IDE can keep running on whatever supports JVM including Windows, macOS, Linux, and Solaris. The equipment it requests is extremely essential:
  • You require at least 0.5 GB RAM at least however, 1+ GB RAM is recommended
  • The next requirement is 300 MB hard disk space however ideally, 1+ GB is recommended
  • You need a Processor that runs with a speed of 800 Mhz at least, 1.5 GHz or faster is recommended

It's anything but difficult to see that the base necessities for Eclipse are progressively unassuming. Since we're not intending to run an IDE on our smartwatch, it's sheltered to accept that even the least expensive PC from a previous couple of years can run both easily gracefully. Notwithstanding, if the execution is what you're searching for, a piece of similar equipment probably won't give you similar outcomes on both the IDEs under discussion.

8). Programming Languages & Frameworks Supported

While we are contrasting IDEs for Java improvement, it bodes well to investigate what different dialects are upheld by your IDE of decision. No one can really tell when you may be compelled to alter JavaScript code or troubleshoot COBOL (ideally never).

SQL Server Quiz

IntelliJ Community Edition underpins Groovy, Java, Kotlin, and XML/XSL straight out of the crate. You can download and introduce modules to enable you to program in: Clojure, CloudSlang, Dart, Elm, Erlang, Go, Gosu, Haskell, Haxe, Julia, Lua, Perl, Python, Rust, and Scala. The systems upheld are Android, Ant, Gradle, JUnit, JavaFX, Maven, Python, SBT and TestNG.

If you require support for HTML/XHTML/CSS, JavaScript, PHP, SQL or different dialects or application improvement systems, you will be compelled to overdo it on an Ultimate release to create in IntelliJ.

Eclipse IDE is written in Java language, so the instruments and SDK for Java advancement are a piece of the fundamental establishment. In any case, because of it being open-source, Eclipse IDE has a colossal biological system of modules that will give you a chance to program with basically every language and structure out-there in one IDE. As of now, with the modules accessible on the Eclipse commercial center, it can bolster more than 100 programming dialects and very nearly 200 application advancement systems.

9). Ease of Use

With regards to convenience, it gets super-difficult to pass judgment. No two clients are the equivalent, and inclination can come down to things like UI customization alternatives or tweakable code culmination. Most designers we've asked affirm the feelings on the Internet – IntelliJ IDE is friendlier to novices on account of its simplicity of code fruition and investigation.

Another preferred position IntelliJ has over Eclipse is that many characterize Eclipse as all the more a gathering of modules than an IDE all alone. So on the one hand, IntelliJ gives you what you need out of the crate. On the other, on the off chance that you need to invest some energy modifying a situation to your particular needs and tinker with the source, Eclipse is the best approach.

Significantly, numerous engineers guarantee that the convenience and smart coding backing offered by IntelliJ is really an impediment in learning and understanding the complexities of Java programming. Of course, a portion of these designers prescribes unassisted coding in a content processor and accumulation in the terminal to drive amateurs to truly realize what they're doing before they incline toward mechanization and AI to do a portion of the work for them. Main concern, "great" coding isn't about set in stone it's tied in with the understanding that coding dialects, and Java explicitly, is a living and breathing thing that changes after some time.

10). Plugin & Extension Ecosystem

As of now, the IntelliJ modules commercial center offers a sum of 3,374 modules, with some of them accessible solely to supporters of the Ultimate Edition, and the Eclipse commercial center incorporates 1,668 arrangements and augmentations for the IDE.

Having picked up ubiquity at a stunning pace, the Community Edition of IntelliJ prompted comparably quickened the development of its module environment in the previous two years. Likewise, with Eclipse module interoperability isn't constantly guaranteed – your mileage may change, all things considered with numerous other open-source arrangements. With IntelliJ IDE, modules are better reviewed by JetBrains and are more averse to conflict with each other.

To an individual developer, the selection wouldn’t necessarily depend on the number of downloadable plugins but rather the availability of specific components needed by the developer to be featured in the IDE of their choice.

For an individual designer, the determination wouldn't really rely upon the number of downloadable modules yet rather the accessibility of explicit parts required by the engineer to be included in their preferred IDE.

11). Popularity

The ubiquity of one IDE over another ought not to be your criteria for the decision. Be that as it may, the size of the network and number of fans among Java engineers can have sway on profitability and usability.

SQL Server training

As recently referenced, IntelliJ IDE has had a developing being a fan since JetBrains discharged the Community Edition in 2001 and surpassed Eclipse in ubiquity in 2016. As indicated by stack share, IntelliJ IDE currently has more fans, more focuses on Reddit, however far fewer inquiries on Stack Overflow.


Knowing the differences between the two most popular IDEs can be a great asset for you. Learn all these differences by heart as it will help you in choosing a better IDE for your respective project. It is also a popular question in the Java interview questions. Therefore, you can use this information there too.
