Difference Between C++ and Java

What is C++?

C++ is a general-purpose, high-level programming language developed as an extension of the C programming language. It combines both procedural and object-oriented programming features, offering a rich set of tools and libraries for system-level and application-level software development. C++ is known for its performance, efficiency, and versatility, making it widely used in areas like game development, system programming, and application development.

What is Java?

Java is a versatile, high-level, and object-oriented programming language known for its platform independence. It is designed to be "write once, run anywhere" and runs on the Java Virtual Machine (JVM), making it suitable for a wide range of applications, including web development, mobile app development (Android), and enterprise-level software. Java is appreciated for its portability, strong security features, and extensive libraries and frameworks.

Applications of C++ Programming Language

• System Software Development: C++ is commonly used for building operating systems, device drivers, and other system software due to its ability to interact closely with hardware.
   
• Game Development: Many computer and console games are developed using C++ because of its performance capabilities and direct access to hardware resources.
   
• Embedded Systems: C++ is favored in embedded systems programming for devices like microcontrollers, where efficiency and control over hardware are crucial.
   
• Performance-Critical Applications: Applications that require high performance, such as real-time simulations and scientific computing, often use C++ for its efficiency.
   
• Graphics and Multimedia: C++ is used in graphics libraries and multimedia applications to manage graphical elements efficiently.
   

Applications of Java Programming Language

• Web Development: Java is widely used for building dynamic web applications, including server-side components, web services, and web-based enterprise software.
   
• Mobile App Development: Java is the primary language for Android app development, making it a key choice for mobile application developers.
   
• Enterprise Software: Java is commonly used in large-scale enterprise applications, such as customer relationship management (CRM) systems and financial software.
   
• Distributed Systems: Java's platform independence and robust networking capabilities make it suitable for building distributed systems and networked applications.
   
• Desktop Applications: Java Swing and JavaFX libraries are used to create cross-platform desktop applications with graphical user interfaces.

C++ Program Example

Let's see a basic program in C++ to find out whether a number is even or odd.
 

Implementation

#include <iostream>
using namespace std;
int main() {
 int number =100;
 if (number % 2 == 0) {
   cout << number << " is an even number." << endl;
 } 
 else {
   cout << number << " is an odd number." << endl;
 }
 return 0;
}

Run Code

Output:

100 is an even number.

Java Program Example

Let's see a basic program in Java to find out whether a number is even or odd.
 

Implementation 

import java.util.Scanner;
public class Odd_Even {
 public static void main(String[] args) {
   Scanner scanner = new Scanner(System.in);
   // System.out.println("Enter a number: ");
   int number = 89;
   if (number % 2 == 0) {
     System.out.println(number + " is an even number.");
   } else {
     System.out.println(number + " is an odd number.");
   }
   scanner.close();
 }
}

You can also try this code with Online Java Compiler

Run Code

Output:

89 is an odd number.

Frequently Asked Questions

Q. Is Java better than C++?

C++ finds primary usage in extensive development for sectors such as banks and governments, while Java is predominantly employed in crafting consumer-centric products like applications, software, and video games.

Q. Is C++ harder than Java?

C++ proves tougher than Java due to its intricate nature and diverse paradigms. Java stands as a beginner-friendly language, suitable for new programmers, while even experts might struggle with C++.

Q. What should I learn first, Java or C++?

Learn Java first if you're new to programming or interested in web development and Android app development. Choose C++ if you want to delve into system-level programming or game development.

Q. Is C++ a dying language?

No, C++ is not a dying language. It's still widely used in areas like game development, system programming, and high-performance computing, and continues to evolve with new standards and updates.

Q. Which is more powerful, Java or C++?

In terms of raw performance and low-level control, C++ is often considered more powerful than Java due to its ability to work closely with hardware and fine-grained memory control.

Conclusion

C++ vs Java is undoubtedly a debatable topic as both are powerful programming languages and are used widely. Both of them have their strengths and weaknesses. C++ is a compiled language that provides greater control over memory management and performance while Java is an interpreted language that is more portable and simple to learn. Java is used for web development, and mobile development whereas C++ is used for game development and system programming. C++ vs Java, if you are a beginner go for Java due to its flexibility and more community support.
