We can consider Java as a general-purpose programming language that is based on object-oriented approaches using class-based methods. Java applications are mainly used to compile the byte code that executes in the background on the ava virtual machine (JVM).

The syntax of Java is equivalent to C and C++ and it was released in 1995. Java is preferable to develop the application for Scientific applications, Embedded systems, and middleware products.

Advantages of Java for software development:

Simple: Java is more specific to use, write, compile, debug, and retain than alternative programming languages. It is much easier than other Object-oriented languages as per its automated memory and garbage collection mechanisms.

Object-Oriented: Object-oriented languages define certain features such as classes, objects, abstraction, inheritance, polymorphism using these developers can easily create modular programming and reusability of code.

Secure: It provides the security mechanism on the compiler, interpreter, and runtime environment
Distributed computing – Java has excellent networking capability. It is organized such that distributed computing is manageable with the networking capacity that is naturally incorporated into it.

Platform-Independent: Java provides the convenience of writing programs in various types of OS and software platforms and it runs on any java-compatible browser. This provides the capability to move code efficiently from one computer system to another with its reusability features.

Robust: It is a robust and reliable programming language. Its compilers can easily catch errors in the coding using exception handling, and garbage collection approaches using these qualities make Java a more robust programming language.

Multithreaded: Java is suitable for performing multiple tasks at a single time. Java is used mainly for finance and stock-based use cases with IoT-enabled devices. It is an open-source technology as Oracle OpenJDK (Java Development Kit). It provides the support of Kotlin, Scala, Groovy, etc.

Disadvantages of Java

Performance: From the performance perspective, Java consumes the memory and comparatively to actively compiled languages like C or C++.

Memory Management: In Java, memory is contained via garbage collection, whenever the garbage collector executes, it impacts the performance of the application. as per the threads have to be controlled to allow the garbage collector thread to perform.

Look and feel: The default look of the GUI applications written in Java is significantly different from the native look.

.Net Core

: Dot NET Core is an open-source framework and enables the capability to handle various types of applications and run into different types of operating systems such as Windows, Linux, and mac-OS operating systems using cross-platform techniques.

Below are the listed features that involve certain techniques.

  • The .NET Core runtime provides a type method, a garbage collector for cleaning up unused resources, native interop, assembly loading, and other important services. The .NET Core framework libraries define primitive data types, fundamental utilities, and app composition classifications.
  • The ASP.NET runtime presents a framework for creating modern cloud-based internet-connected applications, for example, web apps, IoT apps, and mobile backends.
  • The .NET Core CLI tools and language compilers using (Roslyn and F#) allow the most acceptable .NET Core developer experience.
  • The dotnet tool is utilized to establish .NET Core apps and CLI tools. It sets and hosts the runtime, delivers an assembly loading policy, and establishes beneficial apps and tools.
  • Dot NET Core Framework can be utilized to create various kinds of applications such as web, desktop, mobile, cloud, and IoT enabled, machine learning, microservices, and gaming.
  • Dot NET Core contains all the features that are needed to execute a basic Dot NET Core app.
  • It provides the in-built capability of NuGet packages using this developers can easily integrate certain essential packages in the .net Core solution.
  • Dot NET Core application pace up the performance decreases the memory tread and provides the best manageability techniques.
  • The runtime allows the most suitable execution of .NET Core binaries.
  • ASP.NET Core is a framework and a collection of libraries that are willing to operate to create web apps and APIs.
  • .NET Core CLI (common language interface) is the platform CLIs, as it allows developers to create, build, publish, set up, and scaffold their projects.
  • It provides a self-contained solution with .Net Core 3.0 on Windows, Linux, and Raspberry
  • Lesser Code: The most delinquent technology indicates that it uses less coding, making it effortless for the coders to optimize their code using fewer statements.
  • Maintenance: It is easy to maintain as the code written in Dot NET is short. It is easy to understand when new developers start work on the existing application they can easily understand and enhance it as per certain logic.

Disadvantages of Dot NET Core

Tooling is challenging in Dot NET. As per the regular update by Microsoft, When trying to create an application and trying to discover the root cause for a certain exception, it could be a bit challenging because there is a regular update in the documentation that happens on the latest framework.

The documentation of the ASP.NET Core is not significant when compared to different development technologies. It is being updated very repeatedly and any intervals present are being served actively by Microsoft and other supporters for the project.

.Net Core Vs Java

The comparison between Java and Dot NET is mentioned below

Basics Microsoft developed .NET as an open-source framework. and Java was developed by James Gosling it is Java as a programming language that Sun Microsystems then established in 1995.

Target Platforms Both of these languages enable to run the application on Linux and Windows. As per the best principal approach, Linux stages are mainly performed by Java developers and on the other hand, Dot net developers are allowed to use it as per the conditions of the defined windows.

Switch & Strings C# languages provide to use a switch statement on a string variable. Java 7 was the primary discharge that allowed this concept, so more founded Java frameworks do not provide the switch expression sentence structure.

Integrated Development Environment The IDE in Java furnishes a compiler, code editor, and debugger to facilitate the function of code building. The platforms are very user-friendly and beginners can effortlessly begin with them. In the case of Dot NET, Visual Studio is incorporated into it which contains many language-specific components. The IDE performs as a numerous workspace interface that supports development actions such as editing and compiling.

Programming Languages Java and .Net core platforms provide support for standard programming languages, using Ruby and Python. One of the distinctive features of Java is that it defines a single language between different platforms using this program can be written with it operate independently across different OS types.

On the different hand, the .NET framework maintains C#, Visual Basic, F# as per the ability of a multi-programming environment, and Java is based on a single programming language that is a generous approach in supporting multiple.

Why Dot NET is Better Than Java

After the detailed level of understanding on Java and .Net core here we will understand the various factors of why Dot net core is better than Java.

Secure Platform
Dot NET is scanned by Microsoft’s Asp.NET as a closed and secure platform. Hence, security-related issues can be easily addressed and handled professionally and can be used with the latest technologies. As java is open-source, but comparatively from the Dot net core, it has fewer resources and professional support. And Java provides regular updates during runtime that can impact the user experience and annoy many users as per the usage. Dot NET doesn’t encounter such difficulties.

Most Suitable Runtime as CLR
Common Language Runtime(CLR) is excellent in multiple technical parameters than JVM and JRE. As JVM is a compiler it completely translates Java Byte Code into exhaustive instruction for or underlying operating systems, not instantly for computing machines. Hence, it is always lagging and requires regular updates for support of better-operating systems. But using CRL of Dot net developers can not face these challenges.

Most appropriate Programming Languages
Java is a programming language on the other side Dot NET is a framework that utilizes C# for writing codes. Java is an easy-to-learn programming language with rigid patterns and C# is flexible as it is a high-level language with excellent Object-Oriented Programming properties. Hence, newbies usually begin by working with Java and then come into C#.

Powerful IDE
Dot NET operates Visual Studio IDE(Integrated Development Environment), which contains all the tools and important features with modern templates and packages with these tools, developers can develop applications in more robust and simpler ways. It lets developers design, program, test, and debug any classification of application targeted at ASP.NET.

Flexible App Deployment

Using .net core we can deploy a web application with the best Convenience and flexibility abilities we can consider it as a reliable process.

Here are two ways to deploy the web app:

Framework-dependent deployment: This type of deployment is based on shared-system elements. It can be executed only by the app you have created and 3rd party dependencies. This enables saving memory on host systems.

Self-contained deployment: It is not dependent on shared components. The features of .NET Core runtime and .NET libraries are made different from other .NET Core applications.

Worldly-wise Programming Features

The ASP.NET Core stack has robust additional and advanced features These contain:

  • Language independence
  • Asynchronous programming
  • Comfortable to update and customize feature-rich enterprise-grade web applications
  • Excellent development of MVC web applications and RESTful APIs
  • Multiple language support
  • Automatic memory management
  • Cross-platform architecture
  • Package management
  • Garbage collection
  • These features make it more comfortable, quicker, and efficient for developers to create robust and advanced web applications.

What Types of Projects are Best Suited for ASP.NET Core?

Here are the examples of various types of projects and use-cases we can start using ASP.Net core.

Mobile: We can develop mobile-based applications on tablets and smartphones. It is classified into two distinct categories.

Web-based Apps: With Web-based apps, we no need to configure and install procedures and they can be executed via a mobile web browser.

Hybrid Apps: It is about the native portable mobile apps, it can be installed on the device, but internally it can be run on the web apps inside of the application container.

Web Apps: These apps are deployed and can be published to a web server and executed via an internet browser utilizing HTTP and HTTPS protocols. We can consider it as a collection of HTML web pages as a single source of UI and can be run or executed on local or remote networks.

Web Services: It is a web method-based Services that combine with the client through a unique address (URL) with the help of SOAP, XML, and HTTP(S) protocols to access or consume additional services, apps, and components.

Internet of Things (IoT) Apps: They are constructed on the Internet of Things devices and can be developed for any specific use case to get the real-time data and collect and store it into the database from various types of business sources such as industrial automation, automotive, healthcare, smart homes and buildings, wearable technology, and other sources.

To secure the data in ASP.NET project, SSL certificate is also necessary, which secures the data between the server and the browser. To secure ASP.NET application, configure application to use SSL certificate.

When to Choose ASP.NET Core?

As a developer’s thought process sometimes it is confusing when to choose ASP.Net Core. When we have certain requirements to develop an application from the initial stage then we should go with NET Core, as it’s the future design framework. Or if we have our existing application to migrate using .Net Core it provides the best features of migration and compatible techniques on this.

NET Core is one of the most prevalent and valued web-development frameworks to create web apps. Developers can build robust apps faster with the ASP.NET Core Framework. As it’s a cross-platform open-source project with outstanding technical assistance support.

Best Way to Consume JSON from REST API in .NET


You can consume an API in two ways. One is to do it synchronously and the other asynchronously. It is very important to consume APIs and web services. You can create online endpoints using the service oriented architecture so different clients may be able to access it across the web. We communicate many if not most of the digital systems through the Application programming interface (API).

Use of REST

The importance of web APIs is increasing because it gives direct communication lines between the client and the customer for a wide range of applications. Such distributed systems use Representation State Transfer (REST) design models. REST principles set the rules for the design of the web APIs. This results in a simpler and more general web service that is saleable and easier to consume.

We had many powerful service oriented frameworks and technologies that people used though they were not always easy to use. These included the traditional ASP.NET services, XML-based services, WCF services, and SOAP based services. One of the best web based architecture is .NET that has come a long way. One of the reasons is that RESTful services have become predominant model design. This makes consuming and exposing RESTful services easier. But, we cannot say the same of the .Net world.

So, to make it clear, easy and concrete, lets build something right away. We will start with a simple console application project. Fire up Visual Studio (I’m using VS 2012), and create a new console application project.

Consuming JSON REST

Update the new version

When we get to use a new version of the .NET framework and features, we must revise it so we can implement it in a new and easier way. There are many opinions and discussions, techniques and samples on how to sample the .NET applications. To understand it more clearly, the idea is to build something first. This console application project is a simple weather API client. It uses the Open WeatherMap.org JSON API. Through this API, we can locate a city and get the weather forecast for it.

We will implement a simple Weather API client by using the Open WeatherMap.org JSON API. The API will allow us to locate a city location and get the weather forecast information.Lets create a new class to manage the API client logic. Right click on the project, select Add->Class. Name it WeatherApiClient.cs.


To manage the API client logic, we create a new class. Click on the project and click on AddàClass. Name this as WeatherApiClient.cs. To keep it simple, we make the class static so you can call methods straightaway from the main program class. We first implement the synchronous client method. Create a new void method in the class and call it GetWeatherForecast (). Again, make this static.


Two options for methods

We need to use a method to consume the API. You can use two different classes, the WebClient or the HttpWebRequest. In general, we see that the WebClient offers a simpler and easier implementation. The HttpWebRequest allows more control over the execution of the requests. Here we use the WebClient and uses a method called DownloadString (). This method receives a string URL and sends back a response string having the JSON response. You have to add a reference to System.Net in the project to use WebClient.

Here is the main code you need:
public static class WeatherApiClient
	public static void GetWeatherForecast()
		var url = "http://api.openweathermap.org/data/2.1/find/citylat=51.50853&lon=-0.12574&cnt=10";
		// Synchronous Consumption
		var syncClient = new WebClient();
		var content = syncClient.DownloadString(url);
		// Create the Json serializer and parse the response
		DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(WeatherData));
		using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(content)))
			var weatherData = (WeatherData)serializer.ReadObject(ms);

For this, you declare a sample URL then create the WebClient variable. Call the method to pass the URL. Call the method and put a breakpoint to it to check the response from the API. View the JSON response through the Text Visualizer tool. This works straight and gives us the JSON response when we call the API.
