C++ vs. Java: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 26, 2023
C++ is an object-oriented programming language with low-level capabilities; Java is an object-oriented language that runs on a virtual machine.

Key Differences

C++ is a direct successor of the C language, introducing object-oriented features to its procedural predecessor. Java, on the other hand, was designed to be simpler than C++ and to support network computing, which was becoming increasingly important at its time of introduction.

C++ code is typically compiled to machine code for a specific platform. This means software written in C++ needs to be compiled separately for each platform it's meant to run on. Java, conversely, is compiled to bytecode, which runs on the Java Virtual Machine (JVM), making it platform-independent as long as the JVM exists for the platform.

Memory management in C++ is manual, using explicit constructs like "new" and "delete" for dynamic memory allocation and deallocation. In Java, memory management is largely automatic, with the garbage collector reclaiming objects that are no longer in use, eliminating the need for explicit deallocation.

In terms of standard libraries, C++ offers the Standard Template Library (STL) which provides a collection of template classes to help manage data. Java provides a more extensive standard library that covers everything from data structures to networking to graphical user interfaces.

C++ provides more control over system resources and performance due to its proximity to system hardware, making it popular for system/software development and games. Java is generally favored for web applications, mobile apps (Android), and enterprise software due to its platform independence and built-in security features.
