You've probably been thinking about how much work you need to do to create a fully functional and working application. You may be surprised, but sometimes a dozen or so lines of code are enough! We live in such times, that many things are already "written", they work stable, and no one can afford to rewrite them constantly. To tell the truth, almost all modern applications are not fully developed from scratch. Professionals use proven libraries, which significantly influence the time of the coding process, which translates into acceleration of everyday tasks. You should also take advantage of their capabilities!

Must-have each web developer
This course will show you the most useful and used JAVA libraries. You will learn how to use OkHttpfor asynchronous communication withthe Internet. You will learn how to process JSON data in both directions, using the recently popular Gson. Once you masterserialization and deserialization in SimpleXml, you can easily handle XML data. You'll be writing a structured concise code. You'll achieve this with the help of the highly regardedLombokalibrary, which is probably already present in every JAVA project.
Answers to your questions
Probably not once have you looked at the technical documentation to solve your problem and then you thought to yourself with a little disappointment: Why are there no answers to my questions here? I need a manual, not an encyclopedia! Documentation is useful, but very often it does not explain the programming approaches behind which specific methods stand. Here this training comes in handy. You will learnhow to carry out tasks and gain valuable information about libraries, their operation, construction, and which places to look best.
The course presents the way the delegatemodel of events, call-back and deserialization of generic typesworks.The course explains a very popular programming approach based on reversal of dependencies, i.e.dependency injection.Knowledge of the issues presented in the training will allow you to approach the code completely differently. During the course, the following was highlightedsimilarities and rulesThis will help you to learn about other tools yourself in the future.
Work smartly, not hard!
Creating applications performing difficult, advanced tasks does not have to be difficult. You don't have to think about how the code will work, conduct experiments or look for hours of solutions,if the libraries provide us with reliable and ready-made solutions,which may prove to be the foundation of very good applications.Thanks to the training you will check it out with your own hands on functional examples. It turns out that for your application to work you need external data, such as current weather? Do you need current weather data for your application? Do you want to obtain public user data from the social network? You will learn to download them with the help of so-called endpoints, then process them so that you can use them as normal Java objects.
Save time with building systems
Creating runtime files, testing them, different versions of the application - these are the challenges that every programmer has to face. Let's add to this, a few dozen external solutions and the chance for your application to work incorrectly increases dramatically. Fortunatelyyou can avoid it. Enough, knowledge ofbuilding systems like Gradle or Maven. They will allow for easyautomation of tasks, clarification of differences in application versions and will allow for adding new functionalities.
What else is worth knowing?
To start the course you only need basic knowledge of Java. For complete beginners we recommend training:The foundations of Java.
