Java Vs Ruby: Which is Better for Web App Development?

The title says it all. It’s the comparison between Java and Ruby on Rails Programming language.

If you are new to web app development and building a business application, then be aware of the difference.

Both Java and Ruby on Rails are extensively used programming languages and adopted by pioneer brands.

Make a wise decision between the two by checking the end-to-end comparison based on the following key points.

Let’s get started.

Top Brands Using Java

* Google

* Uber

* Airbnb

Top Brands Using Ruby

* GitHub

* Crunchbase

* Bloomberg

* Dribble


Introduction of Java 

Java is an extensively adopted programming language and computing. Sun Microsystems started the inception of Java in 1995 and since then there is no turning back. It runs on JVM (Java Virtual Machine) that helps run any compatible software written and used several times without changing the bytecode. 

If you are keen to develop a web app based on Java, then get connected with a reliable Java software development company. Discuss your requirements with Java experts accordingly. 

Features of Java

Features of Java


Object-oriented language


Static typing

Multithreading capabilities

Automatic garbage collection


Introduction of Ruby

Ruby is an open-source scripting language and is freely available on the web. Yukihiro Matsumoto designed and developed Ruby in 1990. Ruby has similar features to Python and Perl scripting languages. The programming languages focus on easy-to-understand and simple syntax.

Developers use Ruby which simplifies the web app development task and allow to use of fewer lines of coding.

Pros and Cons of Java

What you will like about Java

What you don’t like about Java

1. Static typing feature to build a large codebase

1. Performance might suffer due to compilation and CPU intense features

2. Easy syntax derived from C

2. Java Virtual Machine has an overhead on memory

3. Standard for enterprise computing

3. Verbosity makes the code difficult to read at times

4. Fully backward compatibility

4. Garbage collector might cause little delays

5. Write Once Run Anywhere- build the program in Java and access it anywhere regardless of the operating system

5. Memory leaks

6. Follow Remote Method Invocation (RMI) for distributed computing

6. Long compilation time

7. Automatic garbage collection and memory management


8. Java is the basic and easy to learn a language for the talent


9. An extensive line of educational resources of Java is available


10. Huge ecosystem available to support multiple languages


11. Multithreading capacity


12. Built-in security manager


Pros and Cons of Ruby

What you will like about Ruby

What you don’t like about Ruby

1. Short code length

1. Runtime speed is not that good

2. Reduced development time

2. Incapable to handle projects that require an extensive memory

3. Rapid application development

3. Follow strict rules and guidelines. Something might not be preferred by developers

4. Flexible and easy to understand syntax


5. An extensive ecosystem of tools and libraries


6. Automatic memory management


Java Vs Ruby on Rails 

Java or Ruby? It’s an imperative question to answer. There are several factors based on which we have done the comparison between the two programming languages. 

1. Code Readability: When it comes to code readability Ruby takes the lead with the usual practice of Gems as extended functionality. Whereas in Java, developers use libraries and frameworks to read and understand the code. 

2. Performance: Java performs better in comparison to Ruby. Java is used extensively by popular brands, including the most used Google. It offers an upscale level of performance to web apps belonging to established brands to startups.

3. Scalability: Both the programming languages offer more or less the same scalability. Still, if you have to choose between the two, then make way for Java.

4. Community: Ruby has a bigger community and quick support structure. It helps resolve the issues and answer queries in the shortest possible time. Even Java does not stay behind with having extended community support. 

5. Popularity: Undoubtedly, Java is highly popular than Ruby owing to its early inception and widespread usage. However, Ruby is also gaining traction across the marketplace.

6. Security: Java is highly secure than Ruby-based on better availability of resources and frequent updates. More importantly, Java is designed to create enterprise-level applications having robust security and allows companies to hire Java developers from a reliable tech partner.
