Kotlin for Enterprise Applications using Java EE

By: Raghavendra Rao K

Overview of this book

Kotlin was developed with a view to solving programmers’ difficulties and operational challenges. This book guides you in making Kotlin and Java EE work in unison to build enterprise-grade applications. Together, they can be used to create services of any size with just a few lines of code and let you focus on the business logic. Kotlin for Enterprise Applications using Java EE begins with a brief tour of Kotlin and helps you understand what makes it a popular and reasonable choice of programming language for application development, followed by its incorporation in the Java EE platform. We will then learn how to build applications using the Java Persistence API (JPA) and Enterprise JavaBeans (EJB), as well as develop RESTful web services and MicroServices. As we work our way through the chapters, we’ll use various performance improvement and monitoring tools for your application and see how they optimize real-world applications. At each step along the way, we will see how easy it is to develop enterprise applications in Kotlin. By the end of this book, we will have learned design patterns and how to implement them using Kotlin.

Profiling

Profiling is another technique that is used to understand how the application behaves. In software engineering, profiling is a form of dynamic program analysis that measures various run-time performance parameters such as memory utilization, timing, control flow, and more.

Profiling is used to determine the time spent on each function when the application is running. Profiling tools gather runtime information and record resource utilization including memory, CPU usage, the time spent on functions, and so on. Profiling helps identify problems and looks at the code again to reevaluate the choice of data structures used to optimize for better application performance.

Different tools are available for profiling. Tools such as jvisualvm, jstat, JMC, JProfiler, and so on can be used for profiling applications.
