In this post we will develop a Hello World application using React. Before we starts we need to install node.js and npm on machine.
Download node.js from nodejs.org . For windows and mac download installer, for Ubuntu machines follow Installing nodejs on ubuntu machine using package manager. Continue reading “Getting Started With React : Setting up and building Hello World App in React”
We have already completed Continuous Integration and Continuous Delivery part of vision for application deployment. In this chapter, we cover another stepping stone in achieving end to end automation and that is Continuous Monitoring.

This chapter is a bit more theoretical but covers a premium service of Microsoft Azure platform that can be used for specific use cases that Azure Web Apps may not be able to handle effectively. Other than that, it is important to know why we are covering Azure Web Apps and App Service Environment. The reason behind that is it is equally important to have environment ready for package deployment. When we consider it in the context of Java, we need to deploy WAR file in different environment. Here, we are dealing with Platform as a Service so we need not to worry about installing runtime environment else we also need to find ways to automate it.

In the last chapter, we covered details on Visual Studio Team Services (VSTS). In this chapter, we will see how to utilize VSTS for Continuous Integration. We will use sample spring application available on the GitHub and try to integrate it with VSTS.
We have already seen in the Chapter 2 how to use Team Foundation Version Control; in this chapter, we will also see how to create a project where code is managed in Git.

In this chapter, we will introduces the Visual Studio Team Services and sample application structure that is necessary to understand before automating process of building and deploying application in desired environment. We will cover basics of agile process framework supported in the VSTS. This chapter also explains how to use VSTS to manage Code and integrate VSTS with Eclipse IDE so check in process can be managed directly from IDE.

What is Package?
Package in Java is a way of organizing the code. In simple terms, its an directory or directory hierarchy which is used to store the code files. A statement like import java.util.Scanner means that on system java is a directory which in turns have sub directory name util, which have Scanner class. To create custom package the procedure is to create a directory and sub directories and declare it java file. Consider a class A, which belongs to a package org.demo, save it as A.java.

Comparison plays important role in any programming language. Almost all the sorting techniques involves comparison. In Java, all the predefined classes and primitive data types supports comparison. User defined data types needs to provide the comparison logic, Comparable and Comparator comes in picture. For the primitive data type, how to compare is inbuilt and can be achieved using different comparison operators like <, >, <=, >=. Assume int a = 10 and int b = 20, then a<b is true.
