C++ vs Java | 20 Key Differences between C++ and Java in 2023

Introduction to C++

C++ was additionally recognized by the identify “C with Classes”, which is a common objective object-oriented programming language. Bjarne Stroustrup developed this language in 1979 at Bell Labs. C++ vs Java lets you perceive the essential distinction between every language. It is a multi-paradigm programming language because it helps each procedural and object-oriented programming languages. C++ has the property of the C programming language and the lessons and objects for user-defined knowledge varieties. C++ is used with graphics functions, working methods, desktop functions, high-performance functions, for example, area probes, E-commerce, good watches, sport growth, cloud distributed system, databases, compilers, and so on. This weblog on C++ vs Java will enable you to study concerning the distinction between C++ and Java and the idea of various options.

The C++ is being utilized by high tech giants corporations corresponding to Microsoft, IBM, Google, Meta, Amazon, and so on. C++ has the properties of Object Oriented language corresponding to Encapsulation, Polymorphism, Inheritance, and so on. But with out having lessons and objects, the code of C++ might be compiled, therefore it is usually generally known as a semi object oriented language. Now, it’s not solely an extension of the C programming language however with fashionable updates and excessive efficiency it has turn into a well-liked and in-demand programming language.

History of C++

C++ is a programming language that Bjarne Stroustrup developed in 1979 whereas he was engaged on his Ph.D. thesis at Bell Labs. Stroustrup was making an attempt to create an extension to the C programming language, which might permit for object-oriented programming. He known as this extension “C with Classes,” however it will definitely turned generally known as C++.

C++ was designed to be an extension of C, nevertheless it additionally consists of many new options that aren’t present in C. These embody assist for object-oriented programming, exception dealing with, and templates, amongst others. C++ is a statically typed language, that means the kind of a variable should be recognized at compile time.

Over the years, C++ has turn into a well-liked language for a variety of functions, together with working methods, drivers, browsers, and high-performance computing. It is utilized in many areas of pc science, together with scientific and engineering simulations, knowledge evaluation, and machine studying.

C++ is standardized by the International Organization for Standardization (ISO) and is up to date frequently to replicate the most recent developments within the language. The most up-to-date model of C++ is C++20, which was launched in 2020

History of Java

Java is a programming language and computing platform that was first launched by Sun Microsystems in 1995. It was developed by James Gosling and a crew of builders at Sun Microsystems with the objective of making a language that was simpler to make use of and extra highly effective than different programming languages on the time.

Java was designed to be easy, object-oriented, and extremely moveable, making it simple to put in writing and run code on all kinds of units and platforms. It was additionally designed to be safe, with built-in assist for community communication and knowledge encryption.

One of the important thing options of Java is its use of the “virtual machine” idea, which permits Java applications to run on any system with a Java Virtual Machine (JVM) put in. This implies that Java code might be written as soon as after which run on any system supporting the JVM with out recompiling the code for every platform.

Since its preliminary launch, Java has turn into some of the standard programming languages on this planet, with thousands and thousands of builders utilizing it to construct a variety of functions, from the online and cell apps to backend methods and large-scale enterprise functions. It can be used as a educating language in lots of pc science applications and is a well-liked alternative for learners studying to program.

Features of C++ Language

• Object-Oriented Language (OOPs): C++ is an object-oriented language which means it has properties like lessons, objects, polymorphism, inheritance, encapsulation, abstraction, knowledge hiding, and so on. The OOPs assist in fixing issues successfully, forestall knowledge redundancy and make sure the flexibility of the code.
• Lambda Function: C++ helps the nameless perform known as a lambda expression. The syntax of the lambda perform is given as:

[capture](parameters) -> return_type { function_body }

• Static and Dynamic Memory Allocation: In C++ reminiscence might be allotted throughout compile time that’s static allocation and dynamically i.e., throughout run time. Many occasions, the programmer will not be conscious of how a lot reminiscence can be required to retailer the actual info within the outlined variable, so on this case, the dimensions of required reminiscence might be outlined at run time. The dynamically allotted reminiscence might be allotted utilizing malloc(), calloc(), realloc(), and so on capabilities.
• Fast and Powerful: Being a compiler based mostly language C++ executes the codes quicker. Also, it comprises many built-in capabilities, knowledge varieties, and so on that make C++ a robust language and the primary alternative for the programmer.
• Templates Creation: In C++ templates are used for generic programming, that’s templating is used to create class, generic capabilities, and so on which is used to carry out specific duties for multiple knowledge kind.

Introduction to Java

James Gosling developed Java at Sun Microsystems and it was launched on May 23, 1995. Java programming language is being utilized by hundreds of Software Development Companies and thousands and thousands of builders across the globe. Today, Java is among the hottest languages for growing Software Applications and fixing actual world issues. Java is a high-level object oriented language that helps the function of WORA – Write Once and Run Anywhere, which suggests, compiled Java code might be run on all platforms with none want for recompilation. 

As per the Java dwelling web page, greater than 1 billion computer systems and three billion cell phones use Java programming for utility growth. 

Features of Java Language

• Platform Independent: Java is a platform-independent language, which suggests you possibly can write as soon as and run wherever (WORA). The compiled Java code might be executed on any machine with none modifications. 
• Automatic Garbage Collection: Java is a rubbish collected language, the Java Virtual Machine (JVM) mechanically deallocates the reminiscence blocks, and programmers don’t have to delete them manually, as within the case of C and C++.
• Object Oriented Language (OOPs): Java is a pure object-oriented language. It helps options like encapsulation, polymorphism, inheritance, abstraction, knowledge hiding, and so on. In Java, every part is an Object.
• Multithreading: Java helps multithreading, which suggests a number of duties or capabilities of the identical program can execute in parallel. It helps to maximise the utilization of sources, and applications might be executed sequentially and in a well timed method.
• Memory Management System: Java presents a robust reminiscence administration system that helps to remove errors and verify the code each at compile time and run time.

Difference Between C++ and Java

The beneath desk lets you perceive the distinction between C++ vs. Java

Example of C++ and Java Program

Addition of Two Numbers in c++

#embody <iostream>
utilizing namespace std;
void essential() {
int a, b, sum=0;
cout << "Enter the worth for 2 integers: ";
cin >> a >> b;
// sum of two numbers in saved in variable sum
sum = a + b;
// prints the sum of two numbers 
cout << a << " + " <<  b  << " = " << sum;     
return 0;
}

Addition of Two Numbers in c++

import java.util.Scanner;  // Importing the Scanner class 
class Addition {
  public static void essential (String[] args) {
    int x, y, sum=0;
    Scanner myObj = new Scanner(System.in); // Creating a Scanner object
    System.out.println("Enter the primary quantity:");
    x = myObj.subsequentInt();    // Take the consumer enter
    System.out.println ( " Enter the second quantity:" );
    y = myObj.subsequentInt();   // Take the consumer enter
    sum = x + y;          // Calculate the sum of two numbers x + y
    System.out.println ("Sum is: " + sum);    // Print the sum
  }
}

Similarities between C++ vs. Java
