C Vs Java: Everything you need to know

C vs Java - codeavail

Computer Science students always have a concern between C Vs Java. They are not able to decide which one is the best OOPs language. In this blog, our experts are going to share everything you need to know between C vs Java.

Java Programming

Java is a common-purpose programming language, released by Sun Microsystems in 1995. It is a computing platform for application development pre- Web apps, mobile apps, etc.

C programming

C is a procedural or general-purpose programming language designed by Dennis Richie in 1972. It is older than Java.

Java Hello World Example

  1. public class Hello{
  2. public static void main(String[] args){
  3. System.out.println(“Hello, World”);
  4. }
  5. }

C Hello World Example

  1. #include <stdio.h>
  3. int main(int argc, char ** argv)
  4. {
  5.   printf(“Hello World!\n”);
  6. }

From the graph above (Google Trends), we can say that which one is popular  C Vs Java.

Now, let’s talk about the offering, the features means.

Features of Java-

Java offers many features that make it the king of all programming languages-

Java is simple

It is an object-oriented language

Java is widely used because of its security feature.

Java Runs of JVM, this means it works (write once, run anywhere)

On the other hand,

The features of C show how C becomes the mother of all programming languages-

C programming gives you a structured oriented feature. That will split your code and task with a function.

C is a simple and easy programming language that provides a structured approach to solving your questions in parts.

This allows the user to allocate memory at run time.

With Dynamic Memory Management, you can manually determine your program’s memory requirements at run time.

Pointers in C helps store the memory address as its value.


C follows a top-down approach, which means that the flow of the program is more important than the data it operates on.

Another way, Java follows the down-up approach.

object management-

In C, object management is done manually.

There is a garbage collector in Java, which is automatically managed.


C does not support threads, on the other hand, Java is the opposite.


Java supports overloading for code readability, but not C.

Applications of C Vs Java in the real world

There are many real-time use cases in Java, but it is mainly used to develop applications,

  • Desktop applications
  • Web Applications
  • Desktop applications
  • Mobile app
  • Enterprise app
  • Scientific Application
  • Real-time software
  • Smart Card
  • Cryptography
  • Computer games etc.

C is mainly used to create new programming languages, but there are some important applications of C –

  • Design operating system
  • Design network tools
  • Evaluate Mathematical Equations
  • Create compilers of different languages
  • Developing graphical applications
  • Used in robotics

C is procedure-oriented while Java is object-oriented. To show how difficult the object-oriented will be, I will only tell you what its advantages are on procedure-oriented. Object-oriented is more modular i.e. code can be reused in different programs in the future.


Java is an interpreted language it is first converted to byte code and then JVM (Java Virtual Machine). While C directly compiled. This helps Java achieve more portability, i.e. it can run on most devices.


C is faster than Java in most cases.

Ease of understanding:

Java is easier to understand than c because Java is closer to the English language while c more towards refers to the machine language.


Everything in Java should not be initially declared you can declare it just before using it. Whereas in C you need to declare everything before the actual program starts.

Memory Management:

Java Memory is managed behind the scenes which we call a garbage collector who removes items that are no longer in use. While this user is defined in C, the programmer must use malloc and free functions to clear or allocate memory.

Method overload:

In Java, we can work with the same functions name called the method overloading. While in c you cannot work with the same function name.


Small elements in Java combine to solve the problem while the whole program is first defined in C and then separated into smaller elements.

Error handling: Java errors result in an exception thrown that can be controlled by using various exception handling but if there is an error in C you can do nothing but resolve it.

C Vs Java

  • C programming language is a procedural language. Java is a pure object-oriented language.
  • Header files- In C we use the stdio.h header file. Java does not support any header files.
  • Platform Independent- C is platforms dependant, i.e. you cannot run the equivalent code in another operating system. Java is a platform-independent language.
  • Pointers- We use pointers in C programming language. Java will not support pointers.
  • Operator Overloading– Operator Overloading concept is not in Java.
  • Multiple Inheritance- We not use many inheritances in Java. In Java, we use interfaces instead of many inheritances.
  • Translator- Java uses the compiler and interpreter but uses only the compiler in C.
  • Web application– Internet programming such as frames, the applet is used in Java, not in C.
  • Operator– dot (.) operator is used instead of the scope resolution operator.
  • Package- We can create our package in Java (set of classes) but not in C.

When you compile a Java program, an intermediate bytecode is generated, which is interpreted by the Java virtual machine itself. This way you write a program once, and the virtual machine can translate the bytecode into a command to a particular processor.

Java program execution is slower because the intermediate bytecode has to be interpreted.

Java uses a “Garbage Collectors” The programmable does not have to handle it so it automatically manages memory.

C Programming Language

  • C uses the concept of structures (not object-oriented).
  • In C we use the concept of pointers whereas there are no pointers in JAVA
  • Programmers in C need to manually manage the memory. “Malloc()” ” and “Free ( )” fundamental memory allocations are library calls.
  • We must declare Variables in C at the beginning of the block.
  • C supports statement, structure and union unlike Java
  • C has compiled to the machines “native language”, so it is much faster than the execution of Java.
  • We can’t reuse and publicly the code by default members.

The C program will have a larger memory footprint than the equivalent program written in pure machine code, but the total memory usage of the C program is much smaller than that of the Java program because C does not require the loading of the execution interpreter like JVM.

The main differences between Java and C are speed, portability, and object-orientation.
