Java Vs Ruby on Rails - Which One is Better?

A BATTLE BETWEEN JAVA AND RUBY ON RAILS FOR ENTERPRISE APPLICATION DEVELOPMENT

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 and Ruby which are so far the most used enterprise application development languages. Before you Hire Ruby on Rails Development Team, go through the below comparison:

JAVA Java is a special programming language based on the syntax of the C and C++ programming languages. In 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, the Java developers have succeeded in making the 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. Java is strongly based on C++, making it easy for developers who have already studied this language to learn.

Pros of Java The multiplatform. Perhaps the price for having it is slow, but its main orientation is 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’ Large amount of resources available, both in bookstores and in documentation and community

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.

RUBY on RAILS The programming language Ruby is an interpreted 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 read 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 the, compared to compiled

programs, slightly lower execution speed is made up for by other properties

The language is thus 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 wit 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 system 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, which allows eg Ruby and thus also Ruby on Rails to run wherever a Tomcat container is available.

It serves the purpose in rapid 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.

Javascript and CSS files are minified and compressed, allowing your site to be faster and provide smoother browsing to your users.

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 one of the slower programming languages.

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 are slower.

Key Comparisons to Build Enterprise Applications in Java and Ruby 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, 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.

Runtime environment The Java Runtime Environment 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 are 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 lac 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.

Deployment The topic of deployment plays into the topic of development. In a J2EE environment, a lot of XML files are typically to be edited. 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 server 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 come 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.

Typing 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.

Heredity 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.
