That means bringing your development and operations teams together with shared purpose and regular feedback through DevOps.Ĭontainer adoption supports these practices by offering an ideal application deployment unit and self-contained execution environment. It starts with the people in your organization and the automation processes that help them collaborate. More specifically, it’s a way to build and run responsive, scalable, and fault-tolerant apps anywhere-be it in public, private, or hybrid clouds. These benefits are achieved through self-service and on-demand provisioning of resources, as well as automating the application life cycle from development to production.īut to fully utilize these benefits, a new form of application development is needed.Ĭloud-native development is just that-an approach to building and updating apps quickly, while improving quality and reducing risk. Organizations adopt cloud computing to increase the scalability and availability of apps. Its goal is to deliver apps users want at the pace a business needs.īut what about the "cloud" in cloud-native applications? If an app is "cloud-native," it’s specifically designed to provide a consistent development and automated management experience across private, public, and hybrid clouds. In short, cloud-native app development is a way to speed up how you build new applications, optimize existing ones, and connect them all. They are designed to deliver well-recognized business value, like the ability to rapidly incorporate user feedback for continuous improvement. JnaLib.Cloud-native applications are a collection of small, independent, and loosely coupled services.
JnaLib.printf("\Please Enter Your Name:\n") JnaLib.printf("\nArgument %d : %s", i, args) JNAApiInterface jnaLib = JNAApiInterface.INSTANCE The second Java file is the implementation file which imports the Interface class and calls its API for validation. Public interface JNAApiInterface extends Library Step-3) Create another Java Class to Call C API It is the interface file which contains the definition of the JNA functions defined in “C” library. Next, create a Java class file that loads the C library as mentioned below. Step-2) Create a Java Class to Load C Library
#Cloud native java code example download
The first step for you is to download and import JNA (Java Native Access).Īfter that, you need to create a Java project and import the JNA jar files.
Create a Sample JNA project Step-1) Download JNA Jars It will step-up your coding speed if you are working on Java project making use of C Libraries. JNA, if you compare it with JNI is far easier to use and implement.
For now, let’s focus on learning the JNA concept and its application. We’ll cover the JNI method at length sometime later. It’s also quite popular but requires writing additional Java wrapper code to handle data types and methods of the underlying C/C++ library. There is an alternative method known as JNI which can also load a C/C++ DLL.

It supports multiple platforms and the following C library types.ġ- DLL (Dynamic Link Library) on Windows platforms.Ģ- SO (Shared Object) on Linux platforms. JNA is a platform independent technology to call Native C APIs from the Java code. 2.3 Step-3) Create another Java Class to Call C API.2.2 Step-2) Create a Java Class to Load C Library.
