Difference between Java and C++

Difference between Java & C++

JAVA:

1. Java is a platform-independent programming language because its bytecode can be run on any computer.
2. It is mainly used for application programming, such as window applications, web-based applications, enterprise, and mobile applications.
3. The Java language does not support multiple inheritance through classes; it uses interfaces instead.
4. It uses both a compiler and an interpreter.
5. In Java, memory management is handled by the JVM (Java Virtual Machine), meaning memory is allocated and deallocated automatically.

C++:

1. C++ is a platform-dependent programming language because code written on one computer cannot be run on another without recompilation.
2. C++ is mainly used for system programming.
3. C++ supports multiple inheritance, where code from one class can be used in another. This means you can inherit functions created in one class into another, so you don't have to write them again.
4. The C++ language uses only a compiler.
5. It supports destructors, which are used to destroy memory, allowing for manual memory management.

Explained in Simpler Terms Below:

• Java is a "platform-independent" language, which means you can run it on any computer. C++ is "platform-dependent," so you have to write it separately for each type of computer.
• Java is mainly used for "application programming," like mobile apps and websites. C++ is mainly used for "system programming," like operating systems and drivers.
• Java does not support "multiple inheritance," but C++ does. This means in C++, you can "inherit" from more than one class, which helps avoid repeating code.
• Java uses both a "compiler" and an "interpreter," whereas C++ uses only a "compiler."
• In Java, the "JVM" (Java Virtual Machine) manages memory automatically, while in C++, you have to manage memory manually using "destructors."

Feature	Java	C++
Platform	Platform Independent	Platform Dependent
Primary Use	Application Programming	System Programming
Multiple Inheritance	Not supported (uses interfaces)	Supported
Compiler/Interpreter	Uses both	Uses only a compiler
Memory Management	Automatic (by JVM)	Manual (using destructors)
