C Vs Java: Everything you need to know

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 about
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>

2.  

3. int main(int argc, char ** argv)

4. {

5.   printf(“Hello World!\n”);

6. }

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)

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

Portability:

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.

Speed:

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.

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 platform dependent, 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.

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 machine's “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.
