A Comparison of Two of the Most Popular Programming Languages, C# and Java

Java is one of the most preferred technology and global standard for implementing every kind of app, including web based, client-server, cloud, mobile and enterprise system. Java software development services provide the most reliable technologies that offer a lot of features for building extensive desktop, mobile and web app for valuable clients.

A typical Java web development company has numerous experiences as well as expertise in Java technologies. Java developers possess tech skills for delivering technology and industry-centric services, adhering to CMMi Maturity Level 3 processes that reduce app development time and cost as well as boost software quality.


Sun was the company that introduced Java. And understandably, when it comes to Java development services, it wanted to control the design and evolution. However, Microsoft also wanted a piece of the action, particularly wanted to change Java in certain ways that suited its requirements. This became a legal nightmare, and eventually Microsoft decided that rather than attempting to influence Java, it simply would design its own language, which is C#. It’s better than Java in certain ways, but also very similar in most ways that once a developer learned how to program in C#, it would be trivial to transfer knowledge to Java.

Java and C# Comparison


  1. The Java programming language is designed to be run on a Java platform, with the help of the JRE or Java Runtime Environment. On the one hand, the C# language is designed to be run on the CLR or Common Language Runtime.
  2. In Java, built-in data types, which are passed by value are called primitive types. In the C# language, built-in data types passed by value are called simple types.
  3. Java type safety is safe but C# safety is not.
  4. Java does not support conditional compilation. C# on the other hand supports conditional compilation with preprocessor directives.
  5. Arrays in Java are a direct specialization of Object. But Arrays in C# are System specialization.
  6. Java do not support structures and unions, but C# supports unions and structures.
  7. Java does not support go to statement, but C# does.
  8. Java supports both checked and unchecked exception. C# supports the unchecked exception.


  1. Facebook. The most popular social media also is powered by Java. Facebook makes use of HBase, which is a Java-based No-SQL DB as messaging platform, as well as uses Java in other areas.
  2. eBay. It’s a multinational e-commerce corporation that’s based in San Jose, California, which facilitates consumer-to-consumer and business-to-consumer sales via its website. The architecture of eBay is based on Java.
  3. Google. It uses Java extensively in Google Plus, High Scalability, GTalk and more.
  4. Amazon. Amazon also uses Java, aside from other languages.
  5. LinkedIn. LinkedIn is a business and employment-oriented services, which operates via mobile apps and websites. It’s primarily written in Java.


  1. Banshee. It is a cross-platform open-source media player. It was the default music player for a year in Ubuntu and some time in Linux Mint, but later on was replaced by Rhythmbox in both distributions.
  2. Visual Studio. The Visual Studio of Microsoft is an integrated development environment from Microsoft. Visual Studio includes a code editor that supports IntelliSense and code refactoring as well.
  3. It is a freeware raster graphics editor program for Microsoft Windows. It is developed on the .NET framework.
  4. Colectica. A suite of programs for use in managing statistical surveys and official statistics using open standards, which enable archivists, researchers. Currently, Colectica is in use by various University survey research groups, such as Longitudinal Studies National Statistics Offices, commercial survey research organizations and data archives.

With so much in common, the language to use ultimately would largely depend on the platform chosen for a project. These days, C# is primarily used on the .NET framework, Portable.NET implementations of the CLI and Mono. If the software or web app is being built for Windows, C# would work best with the .NET suite of technologies. This said, if wanting to develop for Linux, Unix or other platforms outside Microsoft, the big open-source ecosystem of Java is the better choice. The community constantly is creating new tools and libraries.

Neither the Java programming language nor the C# programming language would likely disappear anytime soon. Both programming languages have been around for some time that there really is nothing that could not be built in one that could not be done in the other. The bottom line is that the choice all boils down to the language that works best for the platform of choice for a project.
