C++ Vs Java: Difference Between C++ & Java

- Advertisement- Trusted Teller

Object-oriented programming (OOP) is a pc programming precept that focuses on constructing the software program design around “objects” as a substitute of logic or function. An object refers to a data field possessing unique attributes (characteristics). Essentially, OOP places extra emphasis on the manipulation of objects rather than the logic behind the manipulation.

Although C++ vs Java are each object-oriented programming languages, they’re quite different from one another. For example, C++ attracts inspiration heavily from the C programming language and is designed for system development. Nonetheless, Java relies on a secure and portable virtual machine and is explicitly built for application programming and network computing.

In this Article, we’ll dive deeper into the C++ vs. Java debate and learn more concerning the distinction between C++ and Java. 

C++ vs Java: A brief discussion of their history

What’s C++?

C++ is an intermediate-level programming language that mixes the options of the C and Simula (first OOP language) programming languages. C++ encompasses each high-level and low-level options, and it was the primary programming language to introduce the ideas of Class and Objects. It’s appropriate with the foremost platforms, resembling Home windows, Mac OS, and likewise UNIX. 

History of C++

Bjarne Stroustrup developed C++ at AT & T Bell Laboratories within the year 1979. Stroustrup had a imaginative and prescient of juxtaposing one of the best options of C and Simula languages. The thought was to design a language that retains the facility of C whereas also supporting object-oriented programming. Stroustrup developed C++ “with a bias toward system programming and resource-constrained, embedded software program functions and large-scale systems. The core highlights of C++ are high performance, effectivity, and flexibility.

What’s the Java language?

Java is a high-level, class-based OOP language that’s primarily based on the WORA (write as soon as, run anywhere) principle. This means compiled Java code can seamlessly run on all platforms with no need for any recompilation. Sometimes, Java applications are compiled into bytecode to run on any Java virtual machine (JVM), regardless of the underlying system architecture. Java’s syntax is fairly much like C and C++ – it options lesser low-level dependencies.

History of Java

Initially, Java was developed by Sun Microsystems. Sun Microsystems launched the language as the main component of the Java platform within the year 1995. In 2009, after Oracle Co. acquired Sun Microsystems, it turned the proprietor and host of Java and Solaris, the 2 top-class property of Sun Microsystems.

C++ vs. Java: The differences between C++ and Java

Listed here are the main variations between C++ and Java:


Whereas C++ is primarily designed for system programming, Java is constructed for utility programming and is now extensively used for developing web-based, enterprise, and cellular functions.

Root hierarchy

As C++ combines procedural and object-oriented programming, it doesn’t have a strict root hierarchy. Java is a pure OOP language that follows a single root hierarchy.

Platform dependency

C++ is a platform-dependent language, however Java is platform-independent. So, you must compile the C++ source code on each platform. Nonetheless, when you compile the supply code into bytecode for Java, you possibly can efficiently execute it on any other platform. 

Compiler & interpreter

Since C++ is a compiled language, the C++ source code is first compiled into object code after which executed to generate an output. Java is a compiled and interpreted language. The compiled output of a Java source code is a platform-independent bytecode.

Class relationship

In C++, there’s no stringent relationship between class names and filenames. Thus, you possibly can have a number of classes in a C++ program and set something as their filename (the filename and class identify needn’t be the same. Opposite to this, Java enforces a strict relationship between the source code class and the filename. So, the category containing the source code and the filename have to be the same.

Memory management

C++ helps manual memory management. Thus, you might want to allocate or deallocate memory manually utilizing the “new” and “delete” functions. Contrarily, Java helps system-controlled memory management.

C++ helps each single and a number of inheritances, however Java solely helps single inheritance. For a number of inheritances in Java, you might want to use Java interfaces.


C++ helps the overloading of strategies and operators. This course of is known as static polymorphism. Java permits solely method overloading.

Virtual keyword

Since C++ features dynamic polymorphism, it makes use of a digital keyword with a function to indicate that the actual function will be overridden within the derived class. The virtual keyword idea is absent in Java – solely the non-static strategies will be overridden by default. 

Thread support

C++ lacks built-in support for threads, and as a substitute, it depends on third-party libraries for thread support. In contrast to C++, Java has built-in thread support. You possibly can inherit any thread class and override the run method.

Pointers support

C++ offers robust support for pointers and permits developers to put in writing powerful programs utilizing pointers. Nonetheless, Java has restricted support for pointers. So, you can not use pointers in Java as naturally as you possibly can whereas writing a C++ program.

Whereas C++ affords no support for documentation comments, Java helps documentation comments. You should utilize (/** … */) to create documentation comments for Java source code.

Goto statement

C++ helps the goto statement, whereas Java doesn’t support the goto statement.

Call support

C++ has assist for each call by value and call by reference, whereas Java solely helps call by value.


To conclude, C++ vs Java sport quite a few differences regardless of being OOP languages. We hope this text affords you a greater understanding of the important thing differences between C++ and Java
