Overview of this book

Java is one of the most preferred languages among developers. It is 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’ll then focus on understanding object-oriented programming (OOP), with exclusive insights into concepts such as 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 with the help of sample programs and practice examples. You’ll 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 and also build a sample project to help you understand the applications of these concepts. By the end of this Java book, you’ll not only have become well-versed with Java 17 but also gained a perspective into the future of this language and have the skills to code efficiently with best practices.

Garbage collection

Automatic memory management is an important aspect of the JVM that relieves the programmer from the need to do so programmatically. In Java, the process that cleans up memory and allows it to be reused is called GC.

Responsiveness, throughput, and stop-the-world

The effectiveness of GC affects two major application characteristics – responsiveness and throughput:

  • Responsiveness: This is measured by how quickly an application responds (brings the necessary data) to the request; for example, how quickly a website returns a page, or how quickly a desktop application responds to an event. The smaller the response time, the better the user experience.
  • Throughput: This indicates the amount of work an application can do in a unit of time; for example, how many requests a web application can serve, or how many transactions the database can support. The bigger the number, the more value the application can potentially generate and the more user requests...
