Git – Introduction

There are many popular DVCS systems like Git, Mercurial, Bazaar which has grown maturely to implement distributed revision across their products. Git is widely used by the development teams across the world due to its simplicity, active open source the development team  and frequent releases/patches. Before moving forward with the git concepts, few of them terminologies which will be frequently used in this tutorial are defined below :
Remote Repository : This refers to the specific project space on the central server where the project source code is stored and will be used by the team members for checkout or commit.
Local Repository (.git directory): There is a local folder “.git” which is automatically created when the project or folder is git tracked. The “.git” folder is like a local database which will contain all information related to branches, commit history, user configurations, and metadata.
Branches / Tags – Has the same definition as that of SVN /VSS.
Checkout – Since git has a local copy of all branches, a checkout of a branch would always be a local operation and not a remote server call as in SVN. 
Clone – When a git clone command is invoked, the entire remote repository is fetched which includes the branches, tags, commit history and file changes.
Staging Area - is a file located in the project git directory, that stores information about what will go into your next commit.

Right way to close HttpsURLConnetion using try with resources in java 8

HttpsURLConnection does not implement the AutoCloseable interface in Java 8 or later versions.

However, you can create a wrapper class that implements AutoCloseable and encapsulates the HttpsURLConnection object, and then use the wrapper class in a try-with-resources block.

If you are new to Spring batch please check the earlier post about S pring batch introduction In this post we will see Spring boot batch example, Spring boot batch parallel processing example Spring boot batch parallel processing allows multiple batch jobs to run in parallel to minimize the total elapsed batch processing time. This is not a problem as long as the jobs are not sharing the same files, db-tables, or index spaces. If they do, this service should be implemented using partitioned data. We will create the application having the following 2 jobs -  1st Job: Reads the P roduct information from the database and after processing will give the rating to the project. 2nd Job: Reads the Invoice the information the database and update back to the database.  We are not focusing on the business logic here but the processing of data using multiple jobs. Technical Details -  Java 8 Spring Boot 2.x Spring Batch 4.x MySql 5...
