We have two entities that we will use to compare for writing the code using collections in both Java and Kotlin. Our aim is to see the following:
We will use two entities called
Episode . The entities are just for demonstration. You can use anything, like
Money, etc. The Collections API makes working with
Sets fairly simple, and with Streams API introduced in Java 8, iterating over collections is much simpler. There are several operations (called intermediate and terminal) that you can apply to the collections without actually mutating them.
This gives a nice abstraction and better control over concurrency. Kotlin has taken things one step further and abstracted most of the boilerplate when it comes to using Streams. The syntax is much simpler, and it does the same thing with the same speed. With several examples, you will learn how to use Streams in Java and similar implementations in Kotlin.
Let’s initialize the data first.
Email is one of the most universal tools for sharing and receiving information across the globe, with users able to connect with others online with almost no compatibility or access issues. Using this tool, information can be instantly and securely sent to partners on the other side of the world, and personal information can be verified without divulging sensitive data about a user.
Along with this widespread use, however, comes key security measures that must take place in order to ensure the safety of your organization and data. This is particularly the case when receiving email information from previously unknown sources. These risks can include phishing attempts, malware, and other threats that can cause a negative impact to your business. Furthermore, when receiving an email address via account forms and user sign up information, you need to check that the information you are given is not only correct and real, but also that it does not lead to any malicious sources that could harm your organizational security.
The following APIs will allow you to instantly verify and validate an input email address without sending any kind of notification to the email user. This will help protect your organization in the event of any threats. The goal of this tutorial is to provide you with the tools to protect your organization’s information while providing a way to verify new accounts and user information.
This will be done through three separate functions. The first will analyze the validity of an email address’ syntax. The second will check for the address’ servers, and the third performs a full email address validation including returning the results for the previous two functions.

Convert Office Open Document Text File (ODT) to standard PDF, DOCX, PNG, and JPG using Java.
Microsoft has maintained its position in the spotlight for formatted document creation and editing for good reason. Its extreme ease of use and lack of a learning curve has transformed the Microsoft Office Suite into a household name for most computer users in the United States as well as globally. This is propagated further through its almost ubiquitous use in education, as students are raised and taught using these applications.
The issue that arises with these programs, however, is their operation costs. For Apple and other non-Windows-based Operating Systems, the purchasing fees for Office can be steep. This, then, creates a paywall separating potential users from programs to which they are already accustomed. As an answer this problem, Microsoft created the OpenOffice application, which is a free, opensource version of the classic Office Suite. Within this application, you can perform almost all of the same functions as Office Suite, including creating text documents like one would with Microsoft Word. These text documents can be made using OpenOffice Writer, and are formatted using the .ODT file type. While this file type can be opened and saved using OpenOffice Writer and Word, in order to convert the file to a different format such as PDF you will need to run it through a conversion process.
The following APIs will allow you to convert your ODT documents to PDF, DOCX, PNG, and JPG for use in whatever way you need. The goal of this tutorial is to provide a simple and efficient means for instantly converting your ODT files without needing to find or download any extraneous programming.

This article will be looking into one of the most popular questions in Java Language – What is Collection in Java? Also, what do you mean by Collections in Java? Are Collection and Collections the same or different in Java?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.
In this article, we will be installing OpenJDK on Centos 8.

The following five APIs will allow you to create barcode images in the three previously mentioned formats.
Barcodes are used universally in commerce and retail to aid in tracking, purchasing, and inventory. This allows organizations to keep accurate records of their supplies, products, and other items that are pivotal to their operations. For international and national use, there are different barcodes that are utilized for specific contexts. For example, UPC and EAN barcodes look similar in their formatting and can be used in similar ways, but UPC is a largely North American coding system; however, both UPC and EAN are used globally. QR Codes are also used globally but are usually employed for sharing complex sets of information like item details or website links.
The following five APIs will allow you to create barcode images in the three previously mentioned formats. This will allow you to print or create packaging with your personal barcodes attached, without needing to retrieve it from an outside source. This can be especially useful for small businesses as it provides increased independence as a company and improved visual, professional appeal for your products.
