Difference Between C++ vs Java
There are so many differences and similarity given below between the Java Programming Language and C++ Programming (Java vs C++).
| SN | Comparison | C++ | Java |
|---|---|---|---|
| 1. | Platform | C++ is a platform-dependent | Java is a platform-independent |
| 2. | Platform Scope | It cannot run on different platforms, once it compiled. | Write Once Run Anywhere (WORA) – Due to JRE and Byte code, it can be able to run on any platforms. |
| 3. | Origin | Based on C. | Based on C++ and C. |
| 4. | Relationship | C++ was designed to solve a different set of problems. Mainly used for system programming. | Java was not designed to replace C++. Java is mainly used for application programming. |
| 5. | Compiler and Interpreter | C++ uses compiler. | Java uses compiler as well as interpreter. |
| 6. | Concepts | C++ is a partial or semi Object-Oriented Language. | Java is full Object-Oriented Language. |
| 7. | Multiple Inheritance | C++ support multiple inheritances. | Java doesn’t support multiple inheritances because the subclass gets the ambiguity. |
| 8. | Scope resolution operator | C++ support scope resolution operator (::)- A Scope operator is used to defining a method outside the classes and is also used to access the global variable inside the method that contains the local variable with the same name. | Java doesn’t support it. |
| 9. | Overloading | C++ has both features, method overloading as well as operator overloading. | Java support only method overloading. |
| 10. | Threads Supports | C++ doesn’t support any built-in thread mechanism. Third-party libraries need to support threads in a program. | Java supports built-in threads. Import java.lang.Thread inorder to use threads. |
| 11. | Pointers | C++ supports pointers, which points to the address. | Java doesn’t support pointers because of security reasons, if you get the address of any variable then it can be able to breach the security. |
| 12. | Call by value or Call by reference | C++ support both call by value as well as call by reference | Java doesn’t support the call by reference because java doesn’t support pointers. It supports only call by value . |
| 13. | Preprocessor directives | Preprocessor directives (#) is use to include the libraries, C++ support Preprocessor directives e.g #include<iostream>. | Java doesn’t uses Preprocessor directives to include the libraries or class, It uses the import keywords to import any packages e.g import java.util.Scanner; |
| 14. | Memory Management | C++ uses the manual memory management using Mallac(), Realloc(), Calloc(), Free(), and etc. | Java support automatic memory management system known as Garbage Collection. |
| 15. | Intermediate Code | C++ doesn’t generate any byte code (intermediate code) after compilation. C++ generates executable native codes. | Java generates a byte code (intermediate code) after compilation. |
| 16. | Is Case Senstive? | Yes | Yes |
| 17. | Representation of Strings | C++ represents the strings in the form of Array. | Java represents the strings in objects. |
| 18. | Output Format | Using std libraries, Syntax : cout<<"Codenaive"; |
It uses the print() function of System.out class System.out.print(“Codenaive”); |
| 19. | Code Execution | Direct execution by Operating System. | Code is excuted by JVM (Java Virtual Machine ). |
| 20. | Database Connectivity | No | Yes |
| 21. | Sandbox Model | Not Supported | Supported due to JVM. |
| 22. | Templates | Templates are the most powerful features in C++. e.g template <typename T> |
Java doesn’t support templates. |
| 23. | File Extension | .cpp is used as extension for C++ program, e.g hello.cpp. | .java is used as extension, e.g hello.java. |
| 24. | Unions | It supports Unions. | Java doesn’t support Unions. |
| 25. | Structures | C++ support Structures. | Java doesn’t support Structures. |
Conclusion
We learn in this tutorial, how java is related to C++, what is the difference between C++ vs Java. Now, we know that both languages have their own importance at various aspects of features. As discussed, c++ is better in system programming e.g Kernal( creates by C/C++) whereas java is better in an application programming language.
