Difference Between C and Java?: Are they worth your time? [2022]

difference between C and Java

Before we dive deep into our main topic difference between C and Java, it is important for us to have an introduction to both these languages. C was released in 1970 and it has been a language of its time and is still in use even today because of its speed and closeness to machine code.

On the other hand, Java is a programming language that first appeared in 1995 and it is now about 26 years old. Java has been the pioneer language in development because of its speed and efficiency since its arrival. Still, it is being used for a lot of purposes in which no other language is even a close match to Java.

Also, I’ll explain everything that is necessary for the readers to understand this article. I want you to follow along till the end of this article carefully in order to get to know about it in detail.

1. Understanding C and Java Programming Languages?

1.1 What is C Programming Language?

C is a procedural, low level, and compiled language and with the help of its procedural approach, it puts the data through different processes known as procedures and functions when a C program runs. It is also a statically typed language and it is difficult to learn for a beginner in terms of learning and writing programs with it.

C language was developed by an American computer scientist Dennis M Ritchie at Bell Labs and it was first released in 1972. There are a total of 32 keywords used in the C programming language. The best use of C programming language is Operating system development, GUI software development, etc.

1.2 What is Java?

Java was previously owned and first introduced by sun microsystems but later sun microsystems was acquired by oracle corporation which is its current owner. Java is a high-level class-based object-oriented programming language in which every object is dealt with as an object. The best thing about it is that it can be run on any platform no matter if it is windows or mac.

The Java Program code is compiled from a .java file and code is generated in the form of a .class file which is known as bytecode. This bytecode is capable of running on any platform no matter if it’s windows or mac simply with the help of an interpreter called JVM(Java Virtual Machine). It interprets the bytecode into machine code which is readable and executed by the machine.

2. What is the difference between C and Java programming languages?

Difference between C and Java



  1. Java came out as a solution for some tasks that both C and C++ were not capable of doing or not as efficient as Java can. That was also one of the main reasons that Java gets so popular among the developer community.
  2. Java is a platform-independent language which means that it is based on the principle ‘WORA(write once and run anywhere)’. It means that you have to compile the program only once and it’ll be able to run on any platform.
  3. Java is an interpreted language, it means that when the java program code is compiled it generates a code called bytecode and this bytecode is then interpreted using an interpreter called JVM(Java Virtual Machine). This JVM interprets it to the machine code for execution.
  4. Java is much more secure and makes the job easy for developers because it has automatic memory management and garbage collection.
  5. It is a high-level programming language, it means that it is easy for humans to understand, write and learn as its syntax is easy to read as compared to C but it is also slower than C because it is not directly compiled to machine code.
  6. It is used for Mobile application development, desktop application development, web-based application development, game development, dealing with big data, cloud-based application development, IoT application, and Enterprise application development.
  7. Java is a highly portable language i.e. you can take the bytecode anywhere and you can run it on any platform.
  8. Java is the most popular programming language even today for Enterprise level application development.
  9. It is not best known for graphics designing software development because it is not as fast as the C++ programming language.
  10. Java has built-in support for multi-threading which is a very useful feature and it can be used for developing multi-player games, etc.
  1. C is a procedural language and not an Object-Oriented programming language. It means that a program built using C will be built using a procedural approach and when the program is run it will put the data through different processes called procedures and functions.
  2. C is not a platform-independent language but it is a compiled and machine-independent language. It means that the source code in a .C file will be compiled using a compiler and .O files will be generated and then through a linker, these .O files or object files will be linked together and one executable file will be created.
  3. C is a compiled language, its code will be needed to be compiled for every platform in order to run it on a different platform because it is not a platform-independent language.
  4. It is not as secure a programming language as Java is.
  5. It is a low-level programming language, which means that it is close to machine code but also it is difficult for a beginner developer to properly program in it unless he is not well versed in it. Also, its speed is more than Java because it is a compiled language.
  6. It is used to build interpreters for languages like Python and has an interpreter that is also written in C, it is used in IoT(Internet Of Things) applications, for browsers and their extensions as well, for building databases, for developing graphics software that requires high-speed rendering e.g. most of the Adobe applications are developed using it.
  7. It is not a portable programming language and its programs cannot be taken to any platform as it needs to be compiled for every platform.
  8. It is extensively used for writing Desktop applications and Operating Systems Like windows.
  9. It doesn’t support automatic memory management.
  10. It is not as popular as the Java programming language is but still it fulfills a lot of uses even today because of its faster speed.

3. Are they still worth learning in 2021?

Both C and Java are great languages and they serve their respective purposes very well. C, C++, and C# are still the top-notch programming languages for Game development, system software, operating system development, etc. Similarly, Java has remained the most popular programming language until 2019 and is still the most preferred one for large enterprise-level applications.

If you want to learn a language for operating system development, GUI software development, etc. then C is the language you should go for. But if you wish to choose a language for mobile app development, web-based applications, cloud-based applications, and especially large enterprise-level applications then you are good to go with the Java programming language.

4. Conclusion

C and Java are both great languages and one cannot say that one of them can replace the other. But each of them is good for different reasons. So, instead of thinking about which is best among these, one should think that which of them is the best choice for our project based on the requirements of our project.

Whether C fulfills your project requirements or Java, the one that is best suited for your project is the right choice for you. Also, I’ve discussed all the relative concepts in this article in order to provide you with a proper understanding of both these languages.

Let me know in the comment section what do you think about it and what is your preferred choice out of these?
