IntelliJ vs Eclipse: Better IDE for Beginners

This blog post compared Intellij Idea vs Eclipse.

Both IntelliJ and Eclipse are (IDE)s Integrated Development Environments competing with each other in the industry.

IDE basically is an application or a software environment that is used to create and program software.

It generally consists of tools including a code editor, a compiler or interpreter, and a debugger to write programs.

Computer software’s developer use IntelliJ IDEA’s integrated development environment for writing Java programs. A proprietary commercial edition is also available, licensed under the Apache 2 license. Commercial development can be done with both the licensed and unlicensed portions of the property.

Computing and programming are carried out using the Eclipse integrated development environment. In addition to the base workspace, it comes with an extensible plug-in system that allows users to customize the  environment in whatever they wish. 

IntelliJ Vs Eclipse- Comparison

Let’s go down and take a neutral tour through this integrated guide explaining what they are and which one leads the other with its plus points in different aspects.

Java Development

IntelliJ vs Eclipse for Java

This debate is an unending one as users of either IDE think that their selection is better than others. IntelliJ has been taking lead lately because of its smart completion and chain completion.

These are integral components for Java development. These features do not come handy in Eclipse in this fast-moving world.

Users of Eclipse think that it normally gets neglected and people do not really go deeper into measuring the breadth that it carries because of its productivity features including resourceful templates, refactoring support, JUnit 5 Integration, and quick outlines.

So browse your personal biases as you start off to work on a Java project.

memory usage

IntelliJ vs Eclipse memory usage

A study concludes that Eclipse IDE is thought to be more memory efficient than IntelliJ.

IntelliJ generally uses between 1.5 and 4.5 GB of heap while Eclipse requires between 512 MBs and 1.5 GB space for you to perform the desired function.

These figures might vary depending upon your programming needs and the task you’re working on, although this is an estimated idea.

The same study suggests that in object creation, Eclipse IDE creates objects at the rate of 2.4 MB per second, while IntelliJ creates objects at the rate of 69.65 MB per second.

In the creation of more objects, however, the consumption of your CPU has to be higher. But it is also recommended that IntelliJ’s pauses times are relatively better than Eclipse.

But users must keep this in mind that their IDE selection should not be relying upon the speed of their processing and memory usage or consumption.

Productivity of the IDE you select and its friendliness with you as a user should always be preferable when comparing two giant competitors.

shortcut keys

IntelliJ VS Eclipse shortcut keys

I can’t comment as to which one is easier in terms of its shortcut commands. Both Eclipse and IntelliJ have altogether a different set of shortcut keys for their users.

If you have switched from one IDE to another lately, then holding on to a totally different set of shortcut keys right away might be a bit challenging for you.

Just in case if you have switched yourself or any of your projects to Eclipse from IntelliJ, in order for you to organize your imports in IntelliJ, you had to press Control+Alt+O earlier.

Whereas to perform the same function now, you are supposed to hit Control+Shift+O.

For a whole guide of shortcut commands for the compatibility, this KeyMap of JetBrains is highly appreciated.

It can be so much helpful for you in determining the function of each short key. Note these shortcut commands down somewhere or memorize them for your convenience.

Although it is better for you to memorize them before configuring your projects in either IDE.

Else simply keep them handy in any way you like because working with them reduces a lot of time you will have to spend otherwise.

Also, in Eclipse, you can get the list of shortcut keys by pressing Control+Shift+L which is very helpful for new users.

While using IntelliJ, you can also customize keys for yourself which is very useful for those of you who are planning to or have already switched from Eclipse or any other IDE to IntelliJ.

Method of customizing a KeyMap in IntelliJ

Open the settings or Preferences dialogue manually or by pressing control+Alt+S. Then select keymap here and customize your predefined settings accordingly.

for beginners

IntelliJ vs Eclipse for Beginners

For beginners, I would forthrightly say that IntelliJ is relatively easier to use during the process of learning than Eclipse but at users’ own expense.

The learning curve of IntelliJ is considerably faster which makes the experience of development more user-friendly. Most internet users who are also Java programmers have unanimously agreed in testifying the ease of its code completion and inspection in comparison to Eclipse.

For beginners and seasonal programmers, IntelliJ is surely a great help, but for complex and colossal projects, Eclipse may also be deemed favorite because of its wide variety of plugins.

When I said above that IntelliJ is easier at users’ own expense, I had a certain group of people in my mind.

It is of the opinion that the learning of proper coding and decoding might be a car crash if beginners are steadfastly spoiled through IntelliJ’s code completion.

Also, it becomes confusing and a lot more complicated for them in case they have to deal with projects of considerable size later on.

workspace setup

IntelliJ vs Eclipse - easy to setup

Workspace is an area where there are stored preferences, configurations, and temporary information in Eclipse.

While one of the things you might notice initially right after launching your project in IntelliJ is that it does not have any concept of workspace. So this makes a huge difference.

As with Eclipse, you might have been able to work on several projects at the same time, but if you’ve recently switched to IntelliJ, you can only work with one project at once.

A single project of IntelliJ usually is comprised of a set of modules in contrast with a set of projects relying on each other in Eclipse.

So you will have to open each project in a separate window if you are still intent on working this way.

performance

IntelliJ vs Eclipse for performance

The speed of Eclipse is good when you have to deal with projects of larger scale as it is assumed to be coming with more plugins in comparison to IntelliJ.

And because it also indexes the entire project on start-up for you, you really don’t have to wait during the production of your project.

But then the more use of plugins you make of, the heavier your computer gets. This might be troublesome for those of you who are usually struggling with their machines.

On the other hand, the preset code completion by IntelliJ makes your job a lot more easier for you during the project.

Also, when you are working on your current project, you will notice that the speed of IntelliJ is faster than that of Eclipse.

So users must keep the highlighted differences of both Eclipse and IntelliJ in their minds if their concern is simply the performance of both Eclipse and IntelliJ.

IntelliJ Idea vs Eclipse for Selenium

IntelliJ vs Eclipse for selenium

In case you don’t have any idea what it is, Selenium is used for automation testing which is one of the functions of both IntelliJ and Eclipse.

If you are newly introduced to the webdriver of Selenium, then perhaps working with IntelliJ will be a better option because it is not as complex as Eclipse sounds with it.

The more growth you have, the better your understanding will be with both IDEs when testing automation.

Choosing a best IDE for yourself entirely rests on your own choice and interests. If you have just started learning the integration of IDEs with any language, then you will look up to IntelliJ.

But if you are an advanced programmer and have several projects on hand at the same time, then you might also like to go with Eclipse in finishing your tasks.

Whichever option you choose, be sure to think of the underlined points as they’ll help you move forward and pull off.

IntelliJ IDEA

intellij IDE for Beginner programmers

IntelliJ IDEA was first made public in 2001 for programmers to enjoy productive Java. It was developed and is still maintained by JetBrains, and it is licensed by apache 2.0.

It is said to be the most powerful, sought-after, and fully-equipped IDE for Java Developers. Also, it is known for its operations functioning without any plugin hassle.

IntelliJ IDE is available in two editions for its users. Its community edition can be accessed for free while its ultimate edition requires programmers to purchase it.

The community edition of IntelliJ is mostly used by Java and Android developers. It supports a number of other languages apart from Java including Kotlin, Groovy, Clojure, Scala and so on.

It also supports features such as advanced forecasting, code analysis and completion, deep static analysis, intelligent refactoring, debugging, and test-running.

Its ultimate edition comes with most upgraded features for developing web and desktop applications.

It offers its support for the integration of spring and web development frameworks along with Java EE support. For the programmers with projects of higher nature, it is recommended that they purchase it for better and improved results.

Although for beginners and intermediate users, the community edition has still a great quantity and a variety of features and functions for them to work with.

According to an estimate available on JetBrains’ webpage for IntelliJ, 72 percent of Java developers usually choose IntelliJ IDEA to carry out their engagements of app development.

This in itself is a self-explanatory figure to understand IntelliJ’s significance.

Eclipse

Eclipse is an open-source IDE for developing applications and has been giving IntelliJ a hard time in their race due to its own distinguishable features.

It was also released in 2001 and is supported by IBM. Like IntelliJ, it is popular for Java application development and android apps. It supports C/C++, PHP, Python, Perl, and other web projects through extendible plugins.
