Java vs C sharp (Difference between C# and Java)


As technology is growing, by the way, we are using programming, you must be thinking that how? Generally, you may see, that every person playing the video game, and doing online work with mobile and laptop, Actually this all games and software made by using programming language.

Every programmers and reader who is interested in the programming language must know Java vs C sharp topic. However, there are many programming languages but these both languages are very popular in the world of programming.

Java and C sharp are widely used as a programming language in the program. They derive both from C family language and both support OOps concept, but yet there is some difference between Java and C#. Let’s discuss both languages before start Java vs C sharp topic.

I know that you have knowledge about both languages but yet let’s discuss some important point of Java and C sharp languages.

What is the Java language?

Java language is a popular general-purpose programming language. In other words, it is object-oriented, concurrent, class-based, and specifically designed to have as few implementation dependencies as possible. Java language is a fast, secure and reliable programming language.

Java language has the facility for developers to “write once, run anywhere”. It means that compiled Java code can run on all platforms that support Java with no recompilation.

As well as Sun Microsystems which was initiated by James Gosling and released in 1995 as a core component of Sun Microsystems’ Java platform originally developed it.

According to Oracle (the company that owns the Java language), Java runs on 3 billion devices worldwide.

First of all, you should know the history of java. let’s discuss.

History of Java language!

Java language has been made underneath James goose, microphone Sheridan organisation, However, and at the start, it had been developed for tv nevertheless, Java language wasn’t capable for that point cables TV system. thus it’s has begun to use for programming.

Thus they keep Java’s name Oak in the starting as a result of the associate Oaktree was outside of Gosling’s workplace. however then, finally, its name modified to Java that is impressed by Java tea. Ever since then there square measure several java versions launched by “sun microsystem” that concludes it below.

Features of Java Language:

  1. Java language is platform-independent
  2. An object-oriented Language
  3. Java language is fast
  4. Java language is secure
  5. Large Standard Library
  6. Garbage collection.
  7. Architecture-neutral
  8. Network.

Let’s discuss briefly on the above features.


1. Java is platform-independent

 One of the best features of Java programming is if we make any application in java language for a specific platform, thus we can run that code on any Operating system.
Furthermore, you have to do that you have to install JVM in your system.
Also, JVM will convert java coding into bytecode and after that CPU will execute that bytecode with the help of JVM.

2. Object-Oriented

Object-oriented is a concept where any large problems divided into smaller parts by creating an object thus we can use that code again in our programme.

3. Automatic Garbage Collection

When we compile a java programme then it converts into bytecode and this bytecode runs on JVM. However, when the object creates, It creates on the heap.

And Actually, there is no need for some object objects after some time. Garbage collector finds them and deletes to use that space for free.

3. Java language is fast

As you know java code is compiled into Java bytecode by the help of JVM. And JVM executes them in full speed.

4. Java language is secure 

If you want to run your java code then you have to compile first, and so JVM is used for converting code into bytecode.
However, for running JVM code you have to install JVM in your pc, and this JVM updates from time to time with their security features. So we can say Java is a most secure language.

5. Large Standard Library 

It has a large set of the library.

6. Architecture-neutral

As you know there is a fixed memory size for primitive data types in java. besides, if you know about the C language, it occupies 2 Mb memory space for 32-bit architecture and 4 Mb space for 64-bit architecture, where java use 4 Mb for both architectures.

7. Network

Java language is designed for web-based application development.

Let’s move on C# points.

What is the C# language?

C# language is a simple, modern, general-purpose, object-oriented, in other words, the multi-paradigm programming language developed by Microsoft within its .NET initiative led by Anders Hejlsberg.

However, C# language is very much based on C and C++ programming languages, so if you have a basic understanding of C or C++ language, then it will be fun to learn C#.

The syntax of C# language is highly expressive, likewise, it is simple and easy to learn. The curly-brace syntax of C# programming will be instantly recognizable to anyone familiar with C, C++ or Java programming.

Programmers who know any of these languages are typically able to begin to work productively in C# within a very short time.

However, C# language syntax interprets many of the complexities of C++ and provides powerful features such as nullable value types, enumerations, delegates, lambda expressions and direct memory access, which are not found in Java.

Features of C# language:

  1. Object-oriented.
  2. Automatic Garbage Collection.
  3. Standard Library.
  4. Familiar syntax.
  5. Avoid the problem of memory leak.
  6. Modern language.
  7. Typesafe.
  8. Scalable and Updateable.
  9. Component oriented.
  10. Structured programming language.
  11. Rich Library.
  12. Fast speed.

Let’s discuss briefly on the above features.

Features of C# language in the brief


object-oriented is a concept where any large problems divided into smaller parts by creating an object. Therefore, we can use that code again in our programme. C# language supports OOps concept.

Automatic Waste Collection

as we explain above in java. Garbage collection works the same as in java.

Standard Library

Also, it has various functions so that we can develop an application fast.

Familiar syntax

C# syntax is very easy to learn those who already know C and java language they can understand easily.

Avoid the problem of memory leak

The major benefit of C# language is its strong memory backup. However, c sharp programming language contains high memory backup. Hence, memory leakage problem and other such types of problem is not occurring as it happens in the case of Java language.

Finally, we will discuss on our main topic Java vs C# language.

Java vs C sharp (Difference Between C# and Java)

Java language is a high level, secured, robust and object-oriented programming language. While C# is an object-oriented, multiparadigm and modern programming language. However, java is designed to be run on a Java platform, by the help of Java Runtime Environment (JRE) while C# is designed to be run on the Common Language Runtime (CLR). 

However, there are many differences between C# and Java. Some of them are explained in the table.

    5. Call by Reference and reference types can be provided by C# language.


Above in Java vs C sharp topic, I described their definition, its feature, differences between them and similarity in both. Java and C# both are the popular programming language but there are many differences and similarity between them along with there are many advantages of c# and java. However, differences between C# and Java makes them differ from one another. Some points are absent in Java whereas some in C# due to this these points they differ. Above all, Java vs C sharp topic helps the programmer to choose a perfect language for its program that has enough quality which is essential for their program.
