- Pros and Cons of Ruby
Talking about better programming language without defining a specific comparison criterion can be subject to lengthy debate. Many of us are interested in the popularity of languages in various domains (web, mobile, business/desktop, embedded systems), while some are focused on the fastest-growing languages and those most in demand by employers.
Here we have focused on Java vs Ruby, which are the most used enterprise application development languages. Before you hire Ruby on Rails Developer, go through the below comparison.
The Java Affair
Java is a special programming language based on the syntax of the C and C++ programming languages. The development of Java was carefully from the beginning to ensure that certain serious programming errors cannot even occur.
So there are no pointers in Java, and thus, the programmer cannot accidentally access the wrong memory address. Among the programmers, Java is highly valued as an easy-to-learn, object-oriented, secure, and computer-language independent programming language.
In recent years, Java developers have succeeded in making the compiled programming language more and more powerful. Java is a very sophisticated and lightweight programming language that, for a good reason, relinquishes certain features of C++, such as pointers, multiple inheritances, and header files.
Instead, many sophisticated features, such as exception handling, concurrency, and graphical user interface, have been integrated into the Java programming language. Java applications run both under Windows and under MacOS, the various Linux and Unix derivatives, and even in the web browser – and on different processor substructures, whether x86, ARM, or PowerPC.
Comparing Ruby Vs Java, Java is strongly based on C++, making it easy for developers who have already studied this language to learn.
Pros and Cons of Java
Pros of Java
- The multiplatform. Perhaps the price for having it is slow, but its main orientation is the performance itself but the ease to develop applications for different technologies (desktop, mobile, web)
- Once you learn its syntax, they are very easy to alternate.
- It is the JDK, a quite complete class library that can be exploited thanks to a language perfectly oriented to objects that running on the virtual machine, allows you to forget something as cumbersome as memory management (you know, pointers, reservation, and release of memory).
- Something verbose, but that can also be good, leave things ‘clear’.
- A large number of resources available, both in bookstores and in documentation and community.
- Faster than interpreted languages and not much slower than compiled languages as there is always an option; you are not tied to any idea, bookstore, or way of doing things.
Cons of Java
- It is its syntax; if we compare it with C# or Python, we see it quite cumbersome and, unlike its similar in.NET, C# is a language that evolves very slowly.
- Its main objective is not the performance and this although it brings an advantage also a disadvantage.
- It is ES for the creation of multimedia applications or that imply minimally advanced functionality (of computer vision).
- The implementation of generics is not completely object-oriented; has native types; having so many options to choose from can result in complicated decisions when you do not know the options well.
The Ruby Vs Ruby on Rails Matter
The programming language Ruby is an interpreted server-side scripting language. Therefore, no compilation process is required, and the Ruby code is not executed directly by the processor but by a so-called interpreter. This reads the script code and converts it at runtime into processor executable code.
Thus, to run Ruby scripts, an appropriate interpreter must be present on the executing machine. The disadvantage of Ruby vs Java is that compared to compiled programs, slightly lower execution speed is made up for other properties.
Thus, the language is much more flexible and dynamic and allows programming constructs such as reflection, dynamic typing, or dynamic scoping. But above all, it brings the great advantage of Transportability with itself. Ruby code is platform-independent and can run on any machine that has a Ruby interpreter.
Ruby interpreters are available for today’s popular platforms Windows, Mac OS X, and Linux, but some classic operating systems such as MS-DOS, Mac OS 9, or IBM OS / 2 also have sophisticated environments. With JRuby, there is even an interpreter for the Java Virtual Machine JVM, which allows e.g., Ruby for java developers and thus also Ruby on Rails to run wherever a Tomcat container is available.

Pros and Cons of Ruby Language
Pros of Ruby
- It serves the purpose of rapid web development as the first features of your site are emerging rapidly.
- The implementation of new features is made easier; your project can evolve continuously.
- The many default behaviors make it possible to focus more on the real added value of your project: customized functionalities, rich interfaces, interactivity.
- The architecture of the framework “constrains” the developers in their way of coding. A constraint perhaps, but especially the guarantee of having a code “clean” and easily exploitable by other developers.
Cons of Ruby
- Ruby’s support community is not as big as Java support communities.
- Several reference sites that run regularly and sometimes test response programming languages often describe Ruby as a slower programming language.
- Compared to other computer languages, Ruby is quite new and has its own unique coding language. Some programmers consider this a disadvantage because they have to take a lot of time just to learn the language before using it.
- Ruby on Rails development updates is slower.
Ruby vs Java Maturity
How mature is the Java programming language?
- The first stable Java version JDK 1.0.2, known as Java 1, was out in 1996.
- The next one, JDK 1.1 came in 1997, and henceforth the Java 2 Standard Editions J2SE were released in 1998, 2000, and 2002 (J2SE 1.4).
- Sequentially out of order, the next Java update was codenamed Tiger and versioned J2SE 5.0 to emphasize its scalability, maturity, stability, and security.
- Successfully thereafter, Java standard editions 6, 7, 8, 9, and 10 were released in 2006, 2011, 2014, 2017, and 2018.
- In September 2018, a long-term support LTS version of Java SE 11 was released, and in the following order, stable versions 12, 13, 14, and 15 were released last in September 2020.
Looking at the above successful and efficient version history of Java, we can understand the vast community, maturity, stability, and scalability of the Java programming language.
When developing an enterprise application, you indeed need a programming language that is proven and trusted by the public.
How mature is Ruby programming language?
- Ruby on Rails general-purpose programming language – the first stable version released 1.0 in December 2005.
- Next in line was 1.2 released in January 2007.
- The successive 2, 3, 4, and 5 versions of RoR along with their advances that are now extinct, were released over the years from 2007 to 2017.
- The latest version of Ruby on Rails 6.1 was out in December 2020, and the community is waiting for the- to be announced TBA version 7.
Again, after viewing the history of RoR, we can say that the community is strong and has an amazing scope in the future. You can surely rely on the rails framework for your enterprise application development.
Ruby Vs Java Architecture
One by one, we will go through the programming architecture of both the programming languages- Ruby vs Java 2021.
Java Application Architecture
The Java programming architecture will make you understand how the Java code is executed and implemented. There are two consecutive processes- compiling and interpretation. Here is the step-by-step bifurcation that takes place when you run a Java program file.
➼ The code that you write first goes to the Java compiler.
➼ The compiler converts the source code into byte code.
➼ This byte code then moves to the java virtual machine.
➼ Here, the JVM converts the byte code into machine code, and hence your java program is executed.
Rails Application Architecture
Ruby on Rails follows the convention over configuration COC strictly and implements the model view controller MVC architecture so that developers can easily maintain their RoR application. The biggest advantage of using the MVC architecture pattern is that you can keep the business logic and the display of your application separate, and hence your application doesn’t obstruct entirely when something goes wrong. It keeps the model (database), view (frontend), and controller (business logic/ app flow) distinct. Let us understand each term for further understanding.
✦ Model: In an RoR application, the models consist of database information that enables validation and helps them to communicate amongst themselves.
✦ View: The view, frontend of an RoR application consists of HTML pages and several other formats such as PDF, RSS, XML, etc.
✦ Controller: This part interlinks the model with the view- the logic of your application. The controller processes the browser requests and sends the results to the view.
Enterprise Application Development Factors: Ruby on Rails and Java
At Java one comes at present as a serious developer not over. The momentum in the Java area is unbroken. Java is the strategic platform of most major players in the market, only C# can keep up. In comparison of Java vs Ruby in 2021, Ruby is a niche language.
Also, Ruby as a scripting language for Java programmers plays a minor role. About 3/4 of the Java programmers use Jython instead. Below are a few comparisons between Java and Ruby programming languages:
✦ Runtime environment
The Java Runtime Environment JRE is a Sun-created standard. The virtual machine (VM) is a so-called bytecode – interpreter, that is, by a compiler interprets generated intermediate code. There are environments of different manufacturers.
At least one virtual machine with just-in-time compilation and hot-spot technology is available (see Java_HSpot). Up to VM version 1.3 there was criticism of the performance of the virtual machine. The fastest implementation was of course the version supplied by Microsoft, which, however, is no longer developed as a result of several legal disputes. Current Java implementations, if you can say that in a general way, are fast enough. For Ruby, there is one in C written, relatively slow interpreter.
Performance bottlenecks can be compensated by outsourcing to C routines. However, Ruby 2 is being worked on. JRuby allows the execution of pure Ruby code in the Java VM, extensions are left out.
✦ Development Environment
Although Java is compiled, turn-around times are remarkably short. That’s because current development environments like Eclipse use an incremental compiler. Java programmers have access to a phenomenal arsenal of tools that override many seemingly annoying language specifics at first glance.
Among Ruby programmers, it is still widely used to rely on vim or emacs for lack of mature development environments. However, the first commercial development environments are already appearing and both the integration into Eclipse and the FreeRIDE written in FXRuby will be further developed.
The topic of deployment plays into the topic of development. In a J2EE environment, a lot of XML files are typical to edit. In addition, special archive files (Jar, Ear, War, etc.) must be generated. All of this can either be done via plugins integrated into the development environment, or you can use a deploy tool from the application service provider.
For small standalone applications, it is sufficient to master Ant. Webstart addresses the subject of updates. In Ruby, RubyGems develops to the deployment standard. Also, the web framework Ruby on Rails or the continuous integration server Damage Control comes as Gems, therefore (the latter uses even the former). In combination, Rant and Rake offer as build tools. In addition, there are the usual, platform-dependent delivery strategies in both Java and Ruby, such as Windows installer or Debian packages.
Java is strictly typed. Typing is mostly static. But there are type errors, which are found only at runtime. In particular, up to Java 5, developers often had to explicitly designate castings, ie the assumed runtime type itself. Types in Java are classes and interfaces. With Java 5 the compiler was drilled with Generics and Autoboxing. In contrast, Ruby relies entirely on dynamic polymorphism. The type of variable is not fixed until runtime.
Types are always classes. Mixins are Ruby’s answer to Generics and Interfaces. So far, the theory. Enterprise applications in Java are mostly created with J2EE. This framework largely breaks with static typing. Enterprise Java Beans are found as remote objects through a name lookup only at runtime. The code then contains strings and no classes, which makes refactoring even more difficult. In addition, there is a time-consuming and error-prone deployment.
Java, like Ruby, only allows simple inheritance. In Ruby, you can have multiple inheritances, while in Java, you can only declare which interfaces a class implements. In Java, this limitation causes generative programming concepts such as aspect-oriented programming and generics to be more widely discussed and used.

Ruby and Java: Similarities and Differences
Ruby vs Java Similarities
➛ Both Java vs Ruby follows the object-oriented paradigm.
➛ The garbage collector looks after the memory management in both Ruby on Rails vs Java.
➛ Objects in both languages are strictly bound by types. When it comes to Java vs Ruby performance
➛ Both of them have all the same method types- public, private, and protected.
➛ They have embedded doc instruments.
Why Choose Ruby Over Java?
Here are the various reasons why RoR is better than the Java programming langue for developing enterprise applications.
- When it comes to RoR vs Java, RoR helps you write the same program code in comparatively fewer lines.
- You get improved bug-fixing when using RoR.
- Unlike Java, Ruby on Rails code doesn’t need to be compiled, just interpretation.
- When you use Ruby on Rails, your application code becomes readable and flexible.
- Java is quite strict which is not the case with Ruby on Rails. RoR developers can skip few lines of code.
- The way Java requires types for class member variables, that is not the need for ruby on rails.
- Developers can leverage the third-party toolkits like GUI FXRuby, Ruby-GNOME2, Qt, wxRuby, etc.
- Developers can be casual, and RoR language wouldn’t mind they don’t use parentheses.
- Users are free to use private variables.
- Ruby on rails does not need casting or static type checking.
Now, let us look at the other side as well.
Why Choose Java over Ruby on Rails?
Here are the key reasons why you should choose Java over RoR programming langue for developing enterprise applications.
- When comparing Ruby vs Java performance, Java is a clear-cut winner as it offers better application performance.
- As per the Java architecture, the JVM transforms the code into machine code quicker and hence your Java application code is executed speedily as compared to RoR.
- Being the most popular programming language, you have the benefit of finding your solution easily with Java.
In the end, let us revisit the key highlights of both the robust programming languages- Ruby vs Java.
After exploring the needs of your enterprise application development and looking at the similarities and differences between Ruby and Java, choose the favorable one. You may also have the advantage of using both Java and Ruby on Rails together because they enhance each other’s features.
