Java vs C sharp: Top 8 Important Differences To Know

Java is one of the most commonly used languages when it comes to programming languages. It is a high-level and general-purpose programming language. Java uses to develop server-side applications. Along with Java, C sharp is also a popular language. C sharp is a simple, modern and general-purpose programming language that creates multi-platform applications. However, the Java vs C sharp debate has been going on for years. Java was always the king, but with the new features add in C sharp, the debate might change. Both Java and C sharp have their strengths and weaknesses. This blog will discuss some of the differences between Java vs C sharp.

What is Java?

Java is both a programming language and an operating system. Java is a high-level programming language that is robust and secure.

James Gosling regards as the “Father of Java.” Indeed, Java was created in 1995 by Sun Microsystems (which is now an Oracle company).

Furthermore, it is a computer platform for developing applications. As a result, Java is lightning fast, safe, and reliable. In addition, the use of this language for Java application development in laptops, data centres, gaming consoles, scientific supercomputers, mobile phones, and other devices.

Pros of Java

  • Java is a strong programming language because of its superior memory management.
  • In Java, everything is an object that handles both data and behaviour.
  • Java is a basic programming language because it is simple to learn and understand.
  • Its code can execute natively on different platforms, eliminating the need to build it each time.
  • Java is a secure programming language because it does not utilize explicit pointers.

Cons of Java

  • The Java programming language is quite expensive because of its increased processing and memory needs.
  • Java supports automated garbage collection, which the programmer has no control over.
  • Because Java programmes operate on top of the Java virtual machine, they require more memory.

What is C sharp?

C sharp is a general-purpose, object-oriented programming language created by Microsoft in 2000 as part of the.NET strategy. As a result, it’s an excellent option for developers of the web and games. In other words, C sharp is also known as C#.

C# has a multitude of features, making it simple to learn. Many complex tasks abstract away by the language. Thus, while designing logic for an application or game, one does not have to worry about memory management and garbage collection concerns. It’s a higher-level language that’s easier to understand.

Pros of C sharp

  • C sharp is a computer language that works well with Windows.
  • It is simple to locate more C sharp developers, whether on a contract or full-time basis.
  • C sharp is a compiled language, so the code on the server is binary.
  • The majority of internet examples for Net languages are written in C sharp.

Cons of C sharp

  • C# is less versatile since it is highly dependent on the.Net framework.
  • Poor x-platform GUI
  • Because C# is an integral component of the.NET framework, the webserver must run Windows.

Similarities between Java vs C sharp

  • Java and C sharp are server-side, back-end programming languages inspired by the C family.
  • They are both object-oriented programming languages, which means that programmes are built around classes and objects.
  • They are both strong languages that can scale and manage large amounts of data.
  • Java and C sharp are compiled languages; they often run quicker than languages such as Python.

Significant Difference between Java vs C sharp

There are many differences between Java and C sharp programming, which are as follows:


Oracle developed Java, a high-level, robust, and secure programming language.

On the other hand, Microsoft developed C sharp, a programming language that runs on a framework for the Internet.


The design of Java programming language to execute on a Java platform using the Java Runtime Environment (JRE).

Whereas, the design of a C sharp programming language for use with the Common Language Runtime (CLR).


The usage parameter is essential in the difference between Java vs C sharp.

Messaging, web application, and highly concurrent application use in Java programming.

On the other hand, the use of games, mobile development, and virtual reality in C sharp.

Data types

Java provides primitive types as built-in data types.

Whereas, simple types are built-in data types that provide by value in C sharp.

Conditional compilation

Java does not allow conditional compilation.

On the other hand, the C sharp supports conditional compilation by using preprocessor directives.


The next factor is cross-platform in the difference between Java vs C sharp.

Java’s bytecode is extremely efficient for cross-platform use.

C sharp, in comparison to Java, needs to improve on this aspect.


We hope you have enjoyed our Java vs C sharp blog. Whether you are trying to decide what programming language to learn next or already have experience with either language, we hope you found this blog helpful.

Java and C sharp are very similar in many ways. They are both object-oriented programming languages. The use of these languages to create software programs. The use of both to run on the .NET framework. The main difference between the two languages is that Java is cross-platform, meaning that it can run on any platform, and C sharp can only run on Windows.
