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:

C++ vs Java: Which One is Better to Choose for Your Future

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.

Java Program Example

class Simple{  
    public static void main(String args[]){  
     System.out.println("Hello Java programming");  


Hello Java programming 

C++ Program Example

File: main.cpp

#include <iostream>  
using namespace std;  
int main() {  
   cout << "Hello C++ Programming";  
   return 0;  


Hello C++ Programming
