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.

Java Class Library

JCL is a collection of packages that implement the language. In simpler terms, it is a collection of the .class files included in the JDK and ready to be used. Once you have installed Java, you get them as part of the installation and can start building your application code up using the classes of JCL as building blocks that take care of a lot of low-level plumbing. The JCL richness and ease of usage has substantially contributed to Java popularity.

In order to use a JCL package, one can import it without adding a new dependency to the pom.xml file. Maven adds JCL to the classpath automatically. And that is what separates standard library and external libraries; if you need to add a library (typically, a .jar file) as a dependency in the Maven pom.xml configuration file, this library is an external one. Otherwise, it is a standard library or JCL.
