There are about 700 programming languages to choose from when venturing into the world of computer programming . Among them, both C# (pronounced C sharp) and Java are popular options. After you’ve narrowed your choices down to these two, deciding which will be the most useful for you will depend upon what type of programming you want to pursue.
Let’s dive deeper into both C# and Java, discuss the features and examples of both languages, and help you decide which will be the most useful for you.
C# is an object-oriented and component-oriented programming language designed for maximum code reusability. Developed in 2000, the intent of C# is to be simple, general-purpose, and modern, receiving regular updates every few years to remain competitive with industry standards. As of June 2022, the current version of C# is 10.0 .
The language supports both strong and implicit variable typing making it flexible to your preferences. C# has automatic garbage collection, so you do not have to be concerned with manually managing memory or dealing with stale objects. Since C# has language interoperability with other .NET languages, anything written in C#, F#, or Visual Basic is available for use. That results in additional functionality available to you through external libraries and repositories.
When looking at C# versus Java syntax, you will find that C# is less verbose. You can say more with fewer lines, making it a little easier to read.
Microsoft created C# and it can be used to make native Windows applications. It has a robust community you can draw from, and since Microsoft owns it, C# has first-class features and functionality on the Windows operating system.
C# is a general-purpose language, making it is a good choice for many projects. It’s a popular choice for dynamic websites and web applications, and it can take care of all parts of a Model, View, Controller style framework. As a result, it can make calls to a database, handle URL routing, and spit out HTML to the user’s web browser. C# can also be used to create interactive APIs if you want to provide data service to other developers or applications.
If you want to make video games, you’ll be happy to learn that C# is an industry staple. C# and C++ are the languages used for the Unity engine. Cuphead, Subnautica, and Genshin Impact were all made in Unity. CryEngine, Godot, and Stride engines also use C#.
Java is very popular for creating both client and server-side applications. It has a similar syntax to C and C++ but is easier to understand. It also has fewer low-level features since that functionality is handled automatically by the compiler and Java Virtual Machine.
Users and developers alike enjoy Java’s built-in security features. Because compiled Java programs run on the Java Virtual Machine, the program is in a sandbox environment, keeping the user safe from any malicious code that makes its way into the program.
Java’s motto is “Write once, run anywhere.” Once compiled, a Java program can run on any machine with a Java Virtual Machine or JVM. Oracle, Java’s owner, has JVM versions for Windows, Linux, macOS, and Solaris (Oracle’s proprietary UNIX operating system).
The versatility of Java means it can be used to create almost anything. It can make desktop applications, mobile applications, games, website backends and servers, and can even run machines. Wikipedia uses Java for its article search and most stock trading platforms were created with it, as well. Alphabet, Meta, Twitter, and just about any big tech company you can think of all use Java in some way or another, and even the Mars rover control systems use Java.
Thanks to technology today, there are many different options for learning C# versus Java online. One option is to self-learn by using blogs, articles, Youtube videos, etc. It’s important to remember that you can spend all day studying the language, but the best way to learn to code is to dive in and start building.
If self-learning is not appealing to you, you have several other options. First, you can earn your bachelor’s degree at a university. Software engineering and computer science are the two most common majors programmers pursue. Most potential employers will likely prefer a bachelor’s degree, but it’s not always required.
If college is not the best path for you, two other popular options for learning are enrolling in boot camps and completing certificate programs—you even have the option to do both.
Bootcamps are an excellent option if you’re looking for a fast and intense way to learn C# and Java. These are best for those who can commit to a full-time, short-term intensive and prefer hands-on instruction.
Bootcamps typically take place in person at the coding school offering the camp. You’ll have an instructor who can answer any questions you may have and help you overcome any challenges or mental blocks. Most bootcamps offer these intensives for several different programming languages, so whether you’ve decided to learn C# or Java, there’s a camp for you. A quick search of “coding bootcamps near me” should help you find the best option.
You can build a solid foundation or fine-tune skills in your chosen language with certificate programs. Coursera works with world-class universities and companies to offer certificate courses in C#, Java, and many other programming languages.
Once you've made an informed decision on which language you would like to pursue learning—C# versus Java, in this case—look for a certificate program that best suits your needs and get to work. Earning a certificate is an effective way to get the necessary training to prepare you to enter the workplace of your choosing.
