C++ vs Java: Difference and Comparison

Computer programming languages are programs or instructions to communicate with the computer. There are a host of languages used. However, the most common ones include C++ and Java.

C++ and Java are object-oriented programming languages (meaning data is stored in objects) but differ in multiple ways.

Key Takeaways

  1. C is a procedural programming language developed in the 1970s, while Java is an object-oriented programming language developed in the 1990s.
  2. Java includes built-in memory management and garbage collection, simplifying memory allocation and deallocation, while C requires manual memory management by the programmer.
  3. Java is designed for cross-platform compatibility, running on the Java Virtual Machine (JVM), whereas C code must be compiled for a specific platform to run natively.

C++ vs Java

C++ is a general-purpose, object-oriented programming language that can create low-level systems software and high-performance applications. Java is also an object-oriented programming language, but it is designed to be platform-independent, meaning the same code can run on different platforms without modification.

C vs Java

However, the above is not the only difference. A comparison between both the terms on certain parameters can shed light on subtle aspects:

What is C++?

Bjarne Stroustrup of AT & T Bell Laboratories in 1979 first developed C++. C++ is an intermediate programming language (having all properties of C language, i.e., built on C) and both high and low-level language attributes.

C++ is a hybrid language as it supports procedural and object-oriented programming.

The idea behind C++ is “write once and compile anywhere.” C++ language is compatible with other high-level languages and supports various inheritances (even multiple inheritances).

Other advantages include its object-oriented feature, which enables code reusability and provides programmer control over memory management, multi-paradigm programming, exception handling, and function overloading.

C++ is not free from drawbacks. The ordinary ones include more memory consumption due to pointers, security issues, absence of built-in thread management, complexity in a high-level environment, difficulty applying to web applications, and no support for garbage collection.

C++ is mainly used in application and system development.

Other uses where C++ could ideally be deployed include well-known operating systems, digital image processing, 3D graphics, real-time arithmetical simulations, cloud storage, programming telephone switches, and even core-banking application systems.


What is Java?

Java is a multi-purpose, high level and advanced programming language developed in 1991 by Sun Microsystems. Java was initially called OAK but later renamed Java in 1995 to take benefit of the world wide web.

The idea behind the Java language is “Write once, run anywhere, everywhere.” This concept is possible in reality as byte code generated by the Java compiler is independent of the platform and can run on any machine.

Java is an object-oriented language with advanced attributes. Java can run on most systems as Java virtual machines exist for multiple systems.

Java offers several advantages that make the language suitable for web use. Some applications/websites may not even be open or work unless Java is installed.

Java is not free from drawbacks. Java only supports single inheritance though effects of multiple inheritances can be achieved using interfaces.

Other drawbacks of Java include non-compatibility with other languages, more memory consumption, programs taking a long time to run, and increased hardware cost.

Java is mainly used for application programming and is the most preferred language in the software industry. Also, Java is utilized for developing web content.

Java is present on the majority of mobile phones. Other areas of application include business applications, cloud computing, enterprise applications, animation, and gaming. Java is the future of artificial intelligence(AI) and big data.

Main Differences Between C++ and Java

  1. C++ is a procedural, object-oriented programming language that does not follow a specific root hierarchy. Java is an object-oriented programming language having a single root hierarchy.
  2. C++ is based on “Write once, compile anywhere” and is compatible with most other high-level languages. Java is based on “Write once, run anywhere, everywhere” but is incompatible with other languages.
  3. C++ is faster but harder to program. Java is more compact.
  4. C++ only uses a compiler. Java uses both a compiler and an interpreter.
  5. C++ supports operator overloading and multiple inheritances and has support for pointers. Java does not support operator overloading, multiple inheritances, and pointers.
  6. C++ does not provide built-in support for the internet and is not portable. Java has built-in support for the internet, and the byte code is portable and executable on any platform.
