” Want to understand the difference between C and JAVA, you are at the right place!  You might wonder what are these kind of words? “

Here, is a detailed, yet very-easy-to-understand distinctions. (*You can also directly scroll down to the comparison table between C and JAVA).

In the present era, Technologies are changing rapidly. Along with these changes, programming languages are also evolving. The languages C, C++, and Java are the languages which mainly focused. 

These languages hold tremendous value in the market. So in this article, I will throw some light on the difference between C and Java to choose your career or a certification accordingly.

C Language: 

We are going to cover the following points here

  • History of C language
  • Features of C language
  • Applications of C language
  • Advantages of C language
  • Disadvantages of C language

History of C language

C language is a general-purpose, high-level language. C language was developed by Dennis Ritchie in 1972 at BELL Laboratories of AT&T(American Telephone and telegraph), which is located in the USA. 

It was initially created to develop the UNIX operating system. It was first implemented on the DEC PDP-11 computer in 1972. 

Features of C language:

  • C language is simple as it provides a structured approach, which means to break the problem into parts. 
  • It can be executed on different machines, which makes it a machine-independent language.
  • C language is also called middle-level language as it is intended to do low-level programming such as to develop system applications like kernel, driver, etc.
  • It also supports the features of the high-level language. 
  • C language provides a lot of inbuilt functions, which makes development fast. 
  • It also supports features of dynamic memory allocation. 
  • There is a free() function that can free the allocated memory at any time. 
  • C language provides this feature of the pointer, which can interact directly with the memory. 
  • C language is also extensible as can it quickly adopt new features. 

Applications of C language :

  • Operating Systems – The first operating system (i.e., UNIX) was designed using C language.
  • Embedded Systems – C language can be used when working with scripting applications and embedded systems drivers.
  • GUI means Graphical User Interface. C language was used to develop Adobe Photoshop, one of the most popularly used photo editors.
  • Google– Even the google chromium-browser and Google file system were developed with C/C++.
  • MySQL– MySQL is used in DBMS (i.e., Database Management Systems ) was written in C/C++.
  • Games– As C language is relatively faster in performance than Java, so it helped develop many popular games like Tic-Tac-Toe, The Snake game and, The Dino game, etc.

Advantages of C language:

  • There are many advantages of C language
  • It is a powerful and efficient language.
  • Easy to learn
  • Comparison speed is very fast
  • Portable language
  • Built-in functions
  • Qualities to extend itself
  • Middle-level language
  • System programming
  • Helps in understanding the fundamentals of computer theories

Disadvantage of C language:

  • The object-oriented programming feature is not there in C language.
  • Runtime type checking is also not available.
  • It does not provide a namespace feature, so you can’t be able to use the same variable name again in one scope.
  • Constructors and destructors are not available. 
  • C language lacks in exception handling.

Java language:

We are going to cover the following points here:

  • History of Java
  • Features of Java
  • Applications of Java
  • Advantages of Java
  • Disadvantages of Java

History of Java:

Java was developed by James Gosling and colleagues at Sun Microsystems in the early 1900s. Java was intended to be compiled to a bytecode, which is then run by a Java Virtual Machine. It was started as a Project called “OAK” by James Gosling in June 1991.

Features of Java:

  • Java is an Object-oriented Language.
  • Unlike various other programming languages like C/C++, Java is not compiled into a platform that is specific to the machine, but rather it is compiled into platform-independent byte code. 
  • This byte code is distributed over the entire web and interpreted by the JVM (Java Virtual Machine) no matter which platform it is to be run.
  • Java is easy to learn and understand. If you know the basic concept of Object-oriented programming Java, then it would be very simple to master.
  • With Java’s security feature, it enables to development of tamper-free systems and virus-free. There are authentication techniques in Java which are based on public-key encryption.
  • Java compiler produces an architecture-neutral object file format; with the presence of a Java runtime system, Java Compiler enables many processors to execute the compiled code.
  • As Java is architecture-neutral and has no implementation-dependent aspects, which in turn makes Java portable. 
  • Java is robust, as it emphasizes mainly on compile-time error checking and runtime checking and so makes an effort to eliminate error-prone situations.
  • Java’s multi-threaded feature allows us to write programs that can perform multiple tasks simultaneously. This design feature allows the developers to construct interactive applications that can run smoothly.
  • Java provides high performance with the use of Just-In-Time compilers.
  • It is basically designed for the distributed environment of the internet.
  • Java is dynamic in nature. It is said it is more dynamic than C/C++ since it is designed to adapt to an evolving environment. 
  • Java programs can carry a huge amount of runtime information that can be used to verify and resolve access to objects at runtime.

Applications of Java:

  • Desktop GUI Applications.
  • Mobile Applications.
  • Big Data technologies.
  • Web-based Applications.
  • Scientific Applications.
  • Gaming Applications.
  • Business Applications.
  • Enterprise Applications.

Advantages of Java:

  • Java is easy to learn, write, compile, debug.
  • Java is object-oriented. 
  • Java allows us to create modular programs and reusable code.
  • Java is platform-independent. This means we don’t need doesn’t need any special software to be installed to run java code, and they can run on many machines, but the JVM needs to be present on the machine.
  • Java is Multi-threaded. This means it can perform many different tasks at the same time.
  • It is secure, as it doesn’t allow explicit pointers.

Disadvantages of Java:

  • Performance is slower than other languages like C/C++,
  • Java is comparatively more memory consuming then C/C++.
  • Memory Management in Java is managed through garbage collection, So whenever the garbage collector runs, it affects the performance of the application. 
  • This happens because all other threads in the have to stop to allow the garbage collector thread to work efficiently.
