In this guide, we will explore the variances between Java and C#. Prior to delving into their distinctions, it is essential to have an understanding of Java and C# along with their characteristics, instances, and various other aspects.

What is Java?

Java is an object-oriented, versatile, and contemporary programming language that serves various purposes. Initially developed by Sun Microsystems in 1995, it is currently under the ownership of Oracle. Its standout feature is the "Write Once, Run Anywhere" functionality, allowing Java programs to operate on diverse platforms equipped with a Java Virtual Machine (JVM). Java finds application in a range of domains, including web and mobile applications, cloud computing, IoT projects, and enterprise solutions.

Simple Example of Java to Add Two Numbers

Let's consider a basic example to demonstrate how Java operates.

Example

import java.util.*;

public class AddNum {
    public static void main(String[] args) {
        int num1 = 15;   // first number
        int num2 = 18;   // second number
        int sum = num1 + num2;  // adding numbers

        System.out.println("The sum of " + num1 + " and " + num2 + " is: " + sum);
    }
}

Output:

The sum of 15 and 18 is: 33

Explanation:

In this illustration, we are examining a class named AddNum which includes two integer variables, namely num1 and num2, each initialized with specific values. Additionally, an integer variable sum is declared to hold the outcome of adding the two numbers. Subsequently, the addition operation is executed, and the outcome is displayed by invoking the System.out.println method.

Features of Java

There are several features of the Java programming language. Some of them are as follows:

• ✅ Object-Oriented: Java is commonly focused on the concept of objects, which provides better code structure and reusability.
• ✅ Platform Independence: Java compiles code into bytecode that can execute on any device equipped with a JVM.
• ✅ Robust and Secure: It enables error checking and includes built-in security features to prevent vulnerabilities.
• ✅ Multithreading: It enables concurrent task execution, which makes it perfect for interactive applications.
• ✅ Rich Libraries: It includes comprehensive libraries for networking, database access, GUI development, and many more.

Disadvantages of Java

There are several Disadvantages of Java. Some of them are as follows:

• ✅ It runs slower than other programming languages, such as C , C++ , and Python , because it is interpreted by the JVM.
• ✅ Java programming needs higher memory and processing requirements than other programming languages.
• ✅ Java GUI frameworks are less modern than other UI technologies.
• ✅ When we write a Java program, it takes many lines, which makes it less concise than other programming languages.
• ✅ It doesn't provide many functions, such as Free and Delete, over which we don't have any control over garbage collection.

What is the C# Programming Language?

C# (pronounced "C-Sharp") is a contemporary, type-safe, object-oriented programming language created by Microsoft under the leadership of Anders Hejlsberg and his team in 2000 as an integral component of the .NET Framework. This language is frequently employed for developing applications and games on the .NET platform. Its primary objective is to offer flexibility, effectiveness, and security, encompassing various functionalities like exception management, generics, automatic memory management, and asynchronous programming. C# is recognized for its straightforwardness, adaptability, and robust integration with the Microsoft environment.

Simple Example of C# to Add Two Numbers

Let's consider a basic example to demonstrate how C# operates.

Example

using System;

class AddNum
{
    static void Main()
    {
        int x = 15, y = 30, sum;
        sum = x + y;

        Console.WriteLine("The sum of " + x + " and " + y + " is: " + sum);
    }
}

Output:

The sum of 15 and 30 is: 45

Explanation:

In this instance, we are examining a class named AddNum that defines two integer variables x and y, performs their addition, and saves the result in a variable named sum. Subsequently, the result is presented using Console.WriteLine, demonstrating the addition of the two integers.

Features of C# Programming

There are several features of the C# programming language. Some of them are as follows:

• ✅ Object-Oriented: C# supports the four main OOP principles, including inheritance, polymorphism, encapsulation, and abstraction.
• ✅ Cross-Platform: With .NET Core and .NET 5+, C# enables developers to create applications that run on Windows, macOS, and Linux.
• ✅ Rich Libraries: It offers extensive libraries for several tasks, including file handling, networking, and database access.
• ✅ Memory Management: Automatic garbage collection streamlines memory management.
• ✅ Versatile Applications: C# is utilized for web development (ASP.NET), desktop applications, mobile apps (Xamarin), games (Unity), and many others.
• ✅ Modern Features: It includes advanced features, including LINQ (Language Integrated Query), async/await for asynchronous programming, and pattern matching.

Disadvantages of C#

There are several disadvantages of C#. Some of them are as follows:

• ✅ It is slower than other programming languages, such as C and C++, because of the intermediate language compilation.
• ✅ C# applications take more memory because of the intermediate language compilation.
• ✅ It can be complex for beginners because of its object-oriented concepts and syntax.
