Difference between C++ and Java2
| No. | C++ | Java2 |
| 1. | Call through the java Native interface and recently java Native Access. | No backward compatibility with any previous languages. But the syntax is highly influenced by c/c++. |
| 2. | Write once, compile anywhere (WOCA). | Write one, run anywhere/everywhere (WORA/WORE). |
| 3. | It allows procedural programming, functional programming, object-oriented programming, and template meta-programming. | It strongly encourages an object-oriented programming paradigm. |
| 4. | It allows direct calls to native systems libraries. | Pointers, references, and pass-by-value are supported. |
| 5. | Exposes low-level system facilities. | Runs on a virtual machine. Does not always provide full access to the features and performance of the platform on which the software runs. |
| 6. | It only provides object types and type names. | It is reflective, allowing meta-programming and dynamic code generation at runtime. |
| 7. | Optional automated bounds checking. | Normally performs bound checking. HotSpot can remove bounds checking. |
| 8. | It supports native unsigned arithmetic. | No native support for unsigned arithmetic. |
| 9. | It supports classes only and allocates them on heap. | Primitive and reference data types always pass by value. No Pointer. |
| 10. | Explicit memory management. | It supports classes only and allocates them on the heap. |
| 11. | It supports classes, structs, and unions and can allocate them on a heap or stack. | Automatic garbage collection, no concept of destructor, and usage of finalize() is not recommended. |
| 12. | It allows explicit overriding types. | Rigid type safety except for widening conversions. |
Give the advantages of Java over C++.
Advantages of java
Its benefits are as follows:-
- It is a simple programming language.
- It is an object-oriented programming language.
- In this, many computers can be run on one network.
- It is a very secure programming language.
- The feature of memory allocation and garbage collector is also available in this.
Advantages of C++
- The portability feature is available in C++ programming language. With the help of which the user can run the same program on any operating system.
- It is an object oriented programming language, this is its biggest feature. In object oriented programming language, we get features like classes, inheritance, polymorphism.
- It is a multi paradigm language. The term paradigm is used for the styling of the program.
- Memory management feature is also available in C++ programming language.
