Scala v Ruby v Java: Discuss the differences between the three

Businesses are evolving, the need to provide rightful solutions to people are also very

much required, People have grown increasingly impatient and are always willing to

demand a life that is easier and fast. Programming languages such as Java, Ruby and

Scala are now helping businesses scale and implement their strategies with much

lesser costs and giving them an option to think twice before loosing a lot of money.

They have evolved how companies choose how to brand and market their products.

It’s safe to say that the technological revolution is upon us and it is our duty to be a

part of it or be left behind.

The first ever programming language was developed in 1883, they were in their early

days invented to make it easier to develop computer applications. As time has passed,

the applications of programming languages have increased ten-fold, from using to

just develop programs to use it in machine learning, artificial intelligence to help

predict the when the shares will go up or when they will go down. It is safe to say

that computer programming has come a long way.

Scala, Java and Ruby

Java is the oldest amongst the three and was created in 1996 in order to create a new

language that would allow consumer electronic devices to communicate with each

other. Now, known as the language of the internet it’s value has increased. With Java

and it’s OOP principles it provides better security and being very simple to code

makes it very user-friendly. This feature of Java makes it the perfect candidate to use

for developing mobile applications. It is compatible with software such as Android

Studio and Kotlin. Now you must be wondering why only Java? The reason is that it

can run on Java Virtual Machine(JVM), whereas Android uses DVK(Dalvik Virtual

Machine) to execute class files. These files are further bundled as an Android application


Java is also used widely in developing desktop GUI applications. Java also provides

GUI development capability through various means mainly Abstract Windowing

Toolkit (AWT), Swing, and JavaFX. While AWT holds a number of pre-assembled

components like menu, list, button. Swing is a GUI widget toolkit, it provides certain

advanced elements like trees, scroll panes, tables, tabbed panels, and lists.

Java EE platform is designed to help developers create large-scale, multi-tiered,

scalable, reliable, and secure network applications. These applications are designed

to solve the problems encountered by large enterprises. The features that make

enterprise applications powerful, like security and reliability, often make these

applications complex. The Java EE platform reduces the complexity of enterprise

application development by providing a development model, API, and runtime

environment that allow developers to concentrate on functionality.

Scala was invented in 2004 in order to address the criticisms faced by the Java

Language, the language was developed as more suiting to the newer age

advancements and requirements. Still being made on the Java Virtual Machine, it

consists all of our favourite Java Libraries. With all of the advantages offered by Java

writing long, scalable and precise code has always been difficult. It does not really

offer user the window to make small mistakes.

Scala on the other hand is much more user-friendly and gives the user an open

window to make certain small mistakes which do not later come back to bite them

when writing long, scalable codes. With this ease of writing and implementing code and

with its vast libraries of frameworks a lot of mobile applications have opted to go for

Scala instead of Java. Apps like Netflix and LinkedIn have already opted for the


Java is and still is one of the most widely known and used programming language

ever but with time, people’s expectations for results have increased and they have

become much more impatient to deal with things that take too much effort and

time. Scala has proved to be a perfect replacement for Java and can help make a life for

developers much easy once it is integrated into applications such as Android Studio

for app development.

One of the only reasons a person might consider to still using Java over Scala. I feel like

that is the only reason there are people who still use Java. With Scala being relatively

new it has not been integrated that well into all of these software that are helpful

for Android Development. When it’s integration with android studio or with the

invention of new upcoming software which will center around Scala, it certainly

possesses the potential to replace Java and become the future of the internet.

What makes Ruby different?

Ruby is often called a "language of careful balance." It was released in 1995 by

Yukihiro Matsumoto. Matsumoto had in-depth knowledge of multiple programming

languages, including Perl, Smalltalk, Eiffel, Ada, and Lisp. He created Ruby to

combine what he thought were the best features of these programming languages.

Ruby is a very flexible programming language that allows developers to alter how

the language itself works. You can add functionality to core language features or

even remove them if you need. Ruby is also a highly portable, cross-platform

language. Code you write on one operating system will run on Linux, Mac OSX, and

Windows. It will even run in UNIX, DOS, BeOS, OS/2, and more.

Ruby’s rise to fame was in the field of Web Development because of the popular web

development framework Ruby on Rails. Ruby on Rails was first released in 2005, and

it changed how web development was done. Before frameworks like Ruby on Rails,

developers had to spend a lot more time writing code to create a web application.

Ruby on Rails gives web developers everything they need to build a web application.

Rails uses conventions that define the structure of every Rails app, so developers can

spend less time configuring their projects. It has code generators that will generate

parts of your application with a simple command, so developers write less code.

The rapid development that Ruby on Rails makes possible also made it a popular

choice for startups because it allowed a small team of developers to build large

applications quickly. Some sites you may have heard of that use Ruby on Rails

include Github, Shopify, Kickstarter, Twitch, Instacart, Zendesk, SoundCloud,,

Hulu, and Square.

Ruby is also very efficient in helping its users with Static Site Generation, DevOps and

automation, web servers, data processing, and web scraping and scrawling.

Every programming language was developed in order to address the needs of a

programmer to help them write constructive code without that much probability of

them committing an error. Similarly comparing these three languages is

technologically unjust to its founders and users. Java is still the language of the

internet and still widely used by companies due to its large set of libraries, the ease of

writing and scaling its code and adding that with its integration into its

application-based softwares used for developing android and web applications

makes it a no brainer. Scala logically makes more sense to use but with it being new

not a lot of people have gotten a hand on it. It was reported that although its

userbase is constantly on the rise it is still early, early for businesses to fully find

individuals with a perfect grasp on the language and its frameworks.

Ruby is the language that can be said to be the most different out of them all. It was

created in order to find a ‘careful balance’. It involves the programmer being creative

and innovative, it allows its users to alter how it actually works, and this provides the user

an opportunity to display how creative and innovative he or she can be.
