C++ Vs Java | Difference | Comparison

In today's competitive coding, java and C++ are widely used programming languages. These two programming languages are also frequently employed in the sector because of some fantastic characteristics. Because of its effectiveness, fast, speed and dynamic memory use, C++ is a very well-liked programming language. In terms of software development, java is unmatched by any other programming language and is widely employed in the IT sector.  Let us debate C++ Vs Java and understand more about it. 

What is C++?

C++ was designed in 1979 by Bjarne Stroustrup as a high-level, general-purpose computer language. In addition, C++ is an extension of the C programming language. With classes, C. C++ was the first computer language to introduce the concept of object-oriented programming. C++ is an object-oriented programming language that was discovered. It was designed originally for system programming and embedded systems. However, it has subsequently been employed in the creation of several apps. Desktop programs, video games, and servers such as e-commerce, online search, and SQL servers are examples.

What is Java?

An object-oriented programming language called java features a virtual machine platform that enables you to generate applications that can run on almost every platform. the slogan of java was written once, run anywhere.

C++ Vs Java | Difference between C++ and Java: 

  • Java is platform neutral but C++ depends on the platform.
  • C++  was developed by Bjarne Stroustrup at bell labs in 1979 as an extension of the language. Java was developed by James Gosling while he was a Sun Microsystems employee.
  • C++ supports the goto statement, but java doesn't support the goto statement.
  • C++ is mainly used for system programming. Java is mainly used for window-based,  web-based, enterprise, and mobile applications.
  • C++ impacted the creation of C99, Java, JS++, Lua, Perl, PHP, Python, Rust, Seed7, and other programming languages. BeanShell, C#, Clojure, Groovy, Hack, J#, Kotlin, PHP, Python, Scala, and other programming languages were impacted by Java. 
  • C++ was designed for system and application programming. It was a C programming language extension. Java was initially developed as a printing system interpreter and then expanded to accommodate network computing. It was created to be user-friendly and open to a larger audience.
  • Languages like Ada, ALGOL 68, C, ML, Simula, Smalltalk, etc. had an impact on C++. Ada 83, Pascal, C++, C#, and other languages had an impact on Java. 
  • C++ support multiple inheritances. Java doesn't support multiple inheritances through the class. Java interfaces may be used to do that.
  • Java only allows call by value, while C++ supports both calls by value and call by reference. Java does not support calls by reference.
  • C++ support operator overloading. Java doesn't support operator overloading.
  • C++ support pointers. In C++, you may create pointer programmes. Internally, Java supports pointers. However, Java does not support writing pointers. It implies that Java only supports certain types of pointers.
  • The C++ support structure and unions. Java doesn't support structure and unions.
  • C++ doesn't support documentation comments. Java support documentation comment(/** ....*/) to create documentation for java source code. 
  • C++ doesn't have built-in support for threads. In order to support threads, it uses third-party libraries. Java provides built-in support for threads.
  • The >>> operator is not supported by C++. Java supports the unsigned right shift >>> operator, which fills the top of negative values with zero. for a positive integer. That the same way that the >> operator does.
  • C++ uses compilers only. C++ is compiled and runs using the compiler which converts source code into machine code so, C++ is platform-dependent. Java uses both compiler and interpreter. At the moment of compilation, bytecode is created from Java source code. The interpreter executes this bytecode at runtime to produce output. Java is platform neutral since it is interpretable.
  • C++is nearer to hardware. java is not interactive with hardware.
  • C++ always creates a new inheritance tree. Because all classes in Java are subclasses of the object class, there is only ever one inheritance tree used. In Java, the Object class serves as the origin of the inheritance tree.
  • C++ uses cin and cout for an output operation. Java uses the system. in and system.out for output.
  • C++ supports a virtual keyboard so that we can decide whether or not to override a function. Java has no virtual keyboard. All nonstatic methods are by default overridable. So, by default, nonstatic methods are virtual.
  • C++ is an object-oriented language. However, a single root hierarchy is not achievable in the C programming language. Java is also an object-oriented language. however, everything is an object in java. Due to the fact that everything derives from java.lang objects, there is only one root hierarchy.
  • C++ support both global and namespace scope. Java supports no global scope. 
  • pIn C++ programmer is responsible to check the errors. While Java is a system responsible to check errors in the program


It is better to learn more about java for those who are interested in working in the software industry or who already have a position in software engineering because of the diversity and flexibility it offers. However because C++ is far quicker than Java, it may end up being a better programming language for those trying to design operating systems, gaming engines, etc. When great speed is required.  Still, if you have any questions or queries in your mind on C++ Vs Java then please ask us in the comment section below.
