Difference Between C++ vs Java You Should Know 

0 54

C++ and Java are both popular programming languages. But both languages are different from each other in many ways. Nowadays, C++ vs Java programming languages are more used in IT Companies. C++ was designed for applications and system development, and Java is intended to be a virtual machine that is very secure and highly portable.

They have some similarities, But you will read the differences between C++ and Java based on several features and factors in this blog. This blog will surely help you.


Let’s go through the other points to compare C++vs Java languages:-

What is C++?

C++ is a computing programming language. Bjarne Stroustrup developed the C++ language at AT&T Bell Laboratories, and it is mainly used for the development of systems and applications. It was the C++ language that first began in concepts such as classes and objects. 


What is Java?

Java is one of the most widely used programming languages and was first released on computing platforms by Sun Microsystems in 1995. It is used as the Server-side language for most back-end development projects, including big data and Android development. It is commonly used for desktop computing, other mobile computing, numerical computing, and games.  


Difference between C++ vs Java

There are many differences between C++ and Java programming languages. C++ vs java lists are shown below:-



  • Between Class names and filenames, no strict relationship. Header files and implementation files are used for specific classes in C++.
  • I/O input mechanism used in statements and cout, e.g., in » a; cout « b;0.
  • C++ supports only compilers.
  • C source code is compatible, except in some exceptional cases.
  • A flexible model with constant security available.
  • C++ compiles anywhere.
  • Support for Procedural Programming and object-Oriented programming language.
  • The interface allows direct calls to native system Libraries.
  • Memory management access to a programmer.
  • There is no such root hierarchy. C++ supports both procedural and object-oriented programming, and It is called a hybrid language.
  • It supports procedural programming and object-oriented features.
  • C++ has a goto statement. Although, it is not good to use a goto statement.

Example C++ program.


int main()


std::cout <<“Hello World!”:

return 0;




Hello World



  • Enforced is the strict relationship, e.g., The source code for class payroll has to be in pay
  • I/O input mechanism is quite complex, and one byte is read at a time.

      ( is easy, e.g System.out.println(a);

  • Any previous language with no backward compatibility. C/C++ influences the syntax.
  • The model encourages weak encapsulation.
  • Java writes once anywhere.
  • It supports an object-oriented programming model.
  • Interface java native through only call and java native recently access.
  • Memory management system controlled.
  • Java is an object-oriented programming language, and that’s why It follows a single root hierarchy.
  • It supports automatic garbage collection. Java does not support destructors.
  • It has no use as a go-to statement. The keywords got, and const is reserved even if they are not used.

Example Java program


class Simple


public static void main(String args[])


System.out.println(“Hello java”);




Hello Java

Key Difference:-


Codes written in C++ need to be compiled on every platform, and It is a platform-dependent language.Java is platform-independent. Java can be executed on any platform and once compiled into bytecode.


C++ is compiled into an object code that can then execute to produce an output, and it is a compiled language.Java is compiled and interpreted language.


It must be compiled for each platform.C++ code is not portable. However, Java code is translated into byte code. Byte code is portable, and it can execute on any platform.


C++ is manual memory management. We need to allocate and deallocate memory manually using the new and delete operators.Java memory management is system-controlled.


C++ supports various types of inheritances, including one and multiple inheritances.

Problems arise from multiple inheritances, C++ uses the virtual keywords to resolve the problems. Java supports only single inheritance.


C++ is static polymorphism. C++ methods and operators can be overloaded, and Java does not allow the operator to overload.


C++ does not allow the operator to overload, and only Java method overloading is allowed.

The practical keyword is absent in Java. However, Java can override all non-static methods by default or in simple terms. All non-static techniques in Java are virtual by default.



C++ and Java both have a large area of applications. Below is the application of c++vs java languages:

 Applications of C++ Programming language:

  1. Develop powerful software ( like Passenger reservation system).
  2. C++ is majorly used in game development.
  3. C++ writes MySQL.
  4. These are popular applications Adobe Premiere and Illustrator that are scripted in C++.
  5. C++is used in many advanced medical types of equipment like MRI machines and so on.


Application of Java programming language:

  1. Develop Desktop GUI applications.
  2. Develop Android and Mobile applications.
  3. Java applications are fixed technologies like disk players, SIM cards, and so on.
  4. Java Enterprise Edition(EE) gives an API and runtime environment for running powerful enterprise software. 
  5. Web services like Internet connection, web app, and Network applications.


Final words 

In the C++ vs java blog, you have learned in detail about the two most popular languages, their differences, and their similarities. Many students are confused about C++ and Java languages. This blog will help you understand C++ and Java Languages.C++ mainly uses the development system and application, and Java uses web app development and android development.
