Factors Java C++
Memory Management Automatic garbage collection and support heap allocation Automatic garbage collection and support heap allocation
Manual management and support garbage collection named smart pointers
Input and Output Utilize ‘System.in’ for input and ‘System.out’ for output It uses ‘cin for input’ and ‘count for output’ operations
Portability Quiet and portable due to JVM It is dependable, so it is less portable
Overloading Limited options as operation cannot be overloaded It supports operator overloading and custom method
Compatibility Easily integrated and depends on JVM Limited compatibility and depend on OS and compiler
Language High-level programming Low-level programming
Pointers It only exists as an implementation detail for references A pointer can be incremented or decremented to point to a new address
Libraries It has in-build standard libraries and a rich ecosystem It is backward compatible with C, APIs, and operating system
Platform Dependency Java incorporates platform-independent; once it is compiled into ‘bytecode’, it can be implemented on every platform C++ facilitates platform-dependent and requires to be compiled on every platform
Type Strongly typed and object-oriented programming language Combine procedural and object-oriented programming language
Multiple Inheritance It does provide multiple inheritance Support multiple inheritance for complex hierarchy
Structures and Union No structures or unions because of complex data types Members and inheritance are public by default in C++
Real-World Applications Gaming application, desktop app, enterprise, financial, web-based, and mobile operating system Graphic User Interface, database software, video game development, operating system, databases, and web browsers
Performance Slower performance because of startup loading time Faster performance due to low-level language
