In this article, we will try to understand C++ vs Java differences, similarities, which one is better, and so on. There are many similarities and differences between C++ and Java programming languages. Some key differences between C++ and Java are given below in the list:
| Comparison Index | Java Description point | C++ Description Points |
|---|---|---|
| Platform-independent | Java is a platform-independent language. | C++ is a platform-dependent language. |
| Mainly used for | Java is mainly used to develop applications and is widely used in web-based, Windows-based, enterprise, and mobile applications. | Mainly used C++ is in system programming. |
| Design Goal | It was designed and created as an interpreter for printing systems but later extended as a support network computing. It was designed to be easy to use and accessible to a broader audience. | C++ is an extension of the C programming language. It was designed for systems and application programming. |
| Goto | Does not support the goto statement. | Supports the goto statement. |
| Multiple inheritances | It does not support multiple inheritances throughout the class. It can be achieved by using interfaces in java. | Multiple inheritances are supported by C++. |
| Operator Overloading | It does not support operator overloading. | Supports operator overloading. |
| Pointers | You can not write the pointer program in java but it supports pointers internally. | You can write a pointer program in C++ because it supports pointer programming. |
| Compiler and Interpreter | Java uses both a compiler and an interpreter. At the completion time Java source code is converted into bytecode. Then bytecode is at runtime and produces output through an interpreter. | C++ codes are compiled and run using the compiler which converts source code into machine code. |
| Call by Value and Call by reference | Java supports call-by-value only. | Call-by-value and call-by-reference both are suported by C++ programming language/ |
| Structure and Union | It does not support structures and unions. | It supports structures and unions. |
| Thread Support | Java has built-in thread support. | C++ doesn't have built-in support for threads. |
| Documentation comment | (/** ... */) a comment is used for documentation in java to create documentation for java source code. | It does not support documentation comments. |
| Virtual Keyword | Java has no virtual keyword and we can override all non-static methods by default. | C++ supports virtual keywords so that we can decide. |
| Inheritance Tree | Java uses always a single inheritance tree because all classes are the child of the Object class. | A new inheritance tree is created by C++ always. |
| Hardware | Java is not so interactive with hardware. | C++ is nearer to hardware. |
| Object-oriented | Java is also an object-oriented language. | C++ is an object-oriented language. |

class Simple{
public static void main(String args[]){
System.out.println("Hello Java programming");
}
} Output:
Hello Java programming
File: main.cpp
#include <iostream>
using namespace std;
int main() {
cout << "Hello C++ Programming";
return 0;
}
Output:Output
Hello C++ Programming
