C# vs Java: What To Choose For Your Next Application?

There are many programming languages in existence today and two of the most popular ones are C# and Java. Both languages have their own benefits and drawbacks, so it can be difficult to decide which one to use for your project. In this blog post, we’ll be comparing C# and Java in order to help you make a decision.

C# and Java programming languages share features and are used for similar purposes, leaving business professionals and developers perplexed as to which to use.

To begin with, their syntax is very similar. Both are known to be simple to learn, but they are also powerful general-purpose languages, making it difficult to choose which one to learn for those just getting started with programming or looking to expand their portfolio.

Let’s get to know more information about C# and Java in the next section:

What is C#?

C# (pronounced c sharp) is a type-safe general-purpose, object-oriented, and component-oriented programming language created by Microsoft’s Andres Hejlsberg and his team in the year 2000. This language is supported by the .NET platform. It is also included in Microsoft Visual Studio and supports Windows OS applications natively. The two pillars of C# design are modernity in features and simplicity in code. It is constantly updated with new elements and supports numerous integrations.

C#, interestingly, was originally developed as Microsoft’s response to Java’s increasing popularity at the end of the millennium.

What is Java?

Java is a general-purpose class-based object-oriented language developed by James Gosling (Sun Microsystems, now Oracle) in 1995. It is also network-centered and has few implementation dependencies. Java was intended to be a small-scale technology reserved exclusively for interactive cable TV before expanding and becoming one of the most widely used programming languages in the world. Java’s famous paradigm and motto “Write once, run anywhere” (also abbreviated as WORE) reflects the language’s inherent platform, operating system, and compiler independence.

Why should we compare C# and Java?

C# and Java are the perfect rivals. 

Both of them appear to have a lot in common. C# and Java are object-oriented and statically typed programming languages that use similar syntax and a “curly brace.” However, there are numerous factors that distinguish them as well. Java has been an industry standard since its inception. C# has come a long way as a standalone technology since its inception in 1999, based on the logic of JScript. Choosing between C# and Java can feel like a choice between the excitement of cutting-edge solutions and the security of well-known software, which makes it all the more compelling to investigate them thoroughly.

To create a thorough comparison, we will look at both languages’ performance, scalability, features, security, popularity, community, learning curve, speed of development, and cost of development.

C# vs Java: A full comparison

Performance

C# vs Java performance is a hotly debated topic among programmers. However, according to online benchmarks, C# performs better overall. It has a faster response time and uses less CPU power. To be fair, when combined with Just-In-Time compilers, Java also provides high performance. Multithreading architecture is built into both Java and C#, allowing multiple processes to run at the same time.

C# Wins!

Scalability

Internal scalability is not available in Java or C#. If you’re looking for an architecture that needs to support a large number of users or store a growing amount of data, their lack of standardized scalability can be significantly improved by astute Java and C# developers, hardware, and third-party applications like Async and Await (for C#) or NCache (for Python) (for Java distributed cache).

Features

As briefly mentioned in the performance section, multithreading or concurrency is a component of both C# and Java architecture (with Java executing it on a higher level). They also have automatic garbage collection to increase security.

Java is well-known for its portability and independence from specific platforms. Because Java code is compiled in bytecode, it can be executed on any computing machine or operating system without changing the syntax. This also means that Java is architecture-independent, emphasizing their “write once, run anywhere” philosophy. This programming language is network-centric and is intended to be used on the Internet. Among its other distinguishing features are robust memory management and Java’s concurrent accumulators, which have their own class and allow developers to use safe code threading.

C# is popular among developers because of its modern features that make coding easier. C# supports multiple operator overloading, event management with delegates, and indexers, to name a few of its components that contribute to a great coding experience. Programmers can improve code readability and maintainability by taking advantage of excellent lambda support, extension methods, and anonymous types. Furthermore, C# has a large standard library that contains many pre-made solutions for common development and business goals.

Furthermore, Java allows for both checked and unchecked exceptions, whereas C# does not.

None to Win here, it really depends on your requirements and your needs.

Security

Understanding a framework’s dangers can help you avoid them when writing code. Java’s design prioritizes security. Because it is statically typed, it significantly reduces type-related errors, and automatic code verification ensures that the entire code is correct before execution. The majority of Java’s flaws stem from integrated libraries and applications. In comparison, C# is far more vulnerable, particularly to SQL and CMD injections. In some ways, this is due to the large number of C# functions. To avoid problems, Microsoft’s website provides clear guidelines for secure C# coding.

Popularity and talent pool

According to the dev and engineering community Stackshare, approximately 9600 companies currently use Java in their tech stacks, while C# is reportedly used by approximately 2100 companies, placing it more than a fourth lower application-wise. Naturally, the job market for C# vs Java reflects this distinction. Java programmers are in high demand on LinkedIn, IT job boards, and other job search websites, while C# and .NET developers have fewer options. According to Glassdoor, the average salary for a Java programmer in the United States is around $79,000, while C# .NET developers earn less, around $68,500.

The Stack Overflow 2020 Developer Survey, which examines programming language use from the perspective of developers, appears to be consistent with other data on Java vs C# popularity. Java is ranked fifth among the most popular languages, with C# ranking seventh. When developers were asked which languages they preferred to work with, the picture changed. C# ranks nine places higher than Java, with 59.7% and 44.1% of developers expressing satisfaction, respectively.

Community

All programming languages have developers and engineers who prefer strictly one over another or simply enjoy coding with one specific environment or language. When it comes to C# and Java respective communities, it is no different. Both of them have great community support and large libraries that assist in the learning process or in solving particularly tough nuts.

Learning curve

C# and Java have very similar learning curves due to their very similar syntaxes and large communities of professionals and newbies who are always available to help. The good news is that it is not too steep. Neither is as simple as Python, but developers with moderate to advanced experience in the IT field should have no trouble. If you’re looking for a challenge, don’t be discouraged!

Speed of development

When it comes to speed of development, Java has a significant advantage due to its syntax. The syntax of Java is independent of IDEs and compilers and is consistent across all computing platforms. C# was originally designed to work best with the Windows operating system, but with cross-platform successors .NET Core and .NET 5, this issue has been largely addressed. Furthermore, C# promotes code reuse. In the end, having a team of competent web developers who know their programming language inside and out is what matters in the debate of speed and performance Java vs C#.

Cost of development

Syntax, like the speed of development mentioned above, can be important if you need a cross-platform application or intend to expand it in the future. Java’s high processing power comes at a cost: it requires serious hardware to support it. The cost of development is frequently affected by whether a project has its own or outsourced team, the hourly rates of developers, and the project’s complexity. Price estimation works best when your specific idea or technology, as well as its unique characteristics and industry needs, are considered.

Costs depend on the market, labor cost, industry, project specificities and characteristics.
