Learn Java 12 Programming

By: Nick Samoylov

Overview of this book

Java is one of the preferred languages among developers, used in everything right from smartphones, and game consoles to even supercomputers, and its new features simply add to the richness of the language. This book on Java programming begins by helping you learn how to install the Java Development Kit. You will then focus on understanding object-oriented programming (OOP), with exclusive insights into concepts like abstraction, encapsulation, inheritance, and polymorphism, which will help you when programming for real-world apps. Next, you’ll cover fundamental programming structures of Java such as data structures and algorithms that will serve as the building blocks for your apps. You will also delve into core programming topics that will assist you with error handling, debugging, and testing your apps. As you progress, you’ll move on to advanced topics such as Java libraries, database management, and network programming, which will hone your skills in building professional-grade apps. Further on, you’ll understand how to create a graphic user interface using JavaFX and learn to build scalable apps by taking advantage of reactive and functional programming. By the end of this book, you’ll not only be well versed with Java 10, 11, and 12, but also gain a perspective into the future of this language and software development in general.

UDP versus TCP protocols

The differences between the UDP and TCP/IP protocol can be listed as follows:

  • UDP simply sends data, whether the data receiver is up and running or not. That's why UDP is better suited to sending data compared to many other clients using multicast distribution. TCP, on the other hand, requires establishing the connection between the client and the server first. The TCP client sends a special control message; the server receives it and responds with a confirmation. The client then sends a message to the server that acknowledges the server confirmation. Only after this, data transmission between the client and server is possible.
  • TCP guarantees message delivery or raises an error, while UDP does not, and a datagram packet may be lost.
  • TCP guarantees the preservation of the order of messages on delivery, while UDP does not.
  • As a result of these provided...
