Water Tank Monitoring System using reusable libraries

Water is the vital source given to us by our planet. Global warming has reached to alarming state such every living or non-living or non-living organism will become a victim. Although Propagandas are done at scale, every human being on the planet should drive the change. One of the driving factors in reducing water wastage. Wastage of water occurs at various places, and one among them is overflowing water tanks and leakage in water tanks which is not affordable. Water tanks can neither monitor nor control the water level in the tank, leading to a large amount of water wastage. Listed below are the best libraries that can help you create applications to reduce water wastage.

Pharmacy Management System using reusable libraries

Health care industries around the globe are growing day by day. Equally pharmacy industry is rising to the same extent. The pharmacy system stores data, systemizes, and controls the use of the medication process with the pharmacies. The pharmacy management system helps the pharmacist maintain their stock and choose the right medicine by using the computer program. The pharmacist makes use of this system to control the pharmacy reliably. Patients sometimes prefer to visit the pharmacy instead of a doctor for minor illnesses, and the system enables the pharmacist to prescribe over-the-counter drugs for these ailments.

The technique for converting a JSON array to a CSV file using Apache Commons IO in Java can be helpful in several situations where you want to export data stored in a JSON array to a CSV file. This may be helpful in the following cases, for instance:&nbsp;&nbsp;
<ul>
 <li class="ql-align-justify">converting data saved in a database or other storage system that is represented as a JSON array;&nbsp;&nbsp;</li>
 <li class="ql-align-justify">exporting data from a web application or API that returns data in JSON format;&nbsp;&nbsp;</li>
 <li class="ql-align-justify">Transforming data from one format to another is part of the ETL (extract, transform, load) process.&nbsp;</li>
</ul>
&nbsp;
It offers a large selection of classes and methods that can be utilized to carry out different I/O-related operations, including reading and writing files, navigating directories and files, reading and writing to input and output streams, and more. When working with I/O operations in Java, Apache Commons IO is a valuable tool in your toolbox because it is a widely used library.&nbsp;&nbsp;
Here is an example of how you can convert JSON array to CSV using Apache common-io in Java for your application:&nbsp;

Convert json array to CSV using Apache common-io in Java

In Java, MongoClient is a class in the MongoDB-driver library for connecting to a MongoDB database and performing various operations on the data. It is the main entry point for the MongoDB Java driver and represents a pool of connections to a MongoDB server or a replica set. You can use the MongoClient class to perform various operations on the data, such as inserting, updating, and deleting documents, creating and dropping collections, and more.&nbsp;
 
To insert data into a MongoDB collection using the MongoClient class in Java, you can use the insertOne() or insertMany() methods of the MongoCollection class.&nbsp;
<ul>
 <li>insertOne(): A single document can be added to a MongoDB collection using the insertOne() method of the MongoCollection class in the Java driver for MongoDB. It puts a Document object into the collection as an argument.&nbsp;</li>
 <li>insertMany(): Multiple documents can be added to a MongoDB collection using the insertMany() method of the MongoCollection class in the Java driver for MongoDB. It puts a list of Document objects into the collection as an input.&nbsp;</li>
</ul>
 
Here is an example of how to insert a document into a MongoDB collection using Java;

How to insert a document/data into a MongoDB collection using Java

There are numerous libraries in Java that enable working with document files. An extensive and well-liked Java library is XDocReport.&nbsp;
 
A Java package called XDocReport enables you to create reports from documents in various formats, including Microsoft Word, OpenOffice, and others. It can be used to generate reports using information from many different sources, such as databases and XML files. The library enables the ability to add styles, graphics, and other formatting choices to the resultant reports. Popular Java frameworks like Apache POI, Freemarker, and Velocity can be coupled with XDocReport to offer a strong and adaptable solution for producing reports in your Java-based applications.&nbsp;
 
Here is an example of how to convert a docx file to a pdf file using XDocReport in Java:&nbsp;
