Mastering the Java Virtual Machine

By: Otavio Santana

Overview of this book

Mastering the Java Virtual Machine is a comprehensive guide that will take you into the heart of Java programming, guiding you through the intricate workings of the Java Virtual Machine (JVM) and equipping you with essential skills to become a proficient Java developer. You’ll start by understanding the JVM, exploring its architecture and how it executes Java code. Through detailed explanations and real-world examples, you’ll gain a deep understanding of JVM internals, enabling you to write efficient and optimized Java applications. As you progress, you’ll delve into memory management and execution, unraveling the complexities of heap and stack management, garbage collection, and memory profiling. You'll learn how memory is allocated and reclaimed in the JVM, as well as how to optimize memory usage and identify performance bottlenecks in your applications. With this knowledge, you’ll be able to create Java programs that are not only robust but also highly performant. By the end of this book, you’ll have the skills needed to excel in Java programming, writing efficient, maintainable code.

Reflection

The Reflection API is a powerful and versatile tool that enables developers to access the inner workings of Java programs. In this chapter, we will explore the various capabilities of reflection, such as field access, method invocation, and proxy usage. Reflection allows developers to inspect and manipulate classes and objects at runtime, providing a dynamic gateway into JVM internals. Throughout this chapter, we will delve into the nuances of reflective field interactions, the intricacies of dynamically invoking methods, and the strategic deployment of proxies to enhance code flexibility. Join us on a journey into the heart of Java’s reflective capabilities, where the seemingly unchangeable becomes adaptable, and the boundaries of static code are stretched to accommodate the dynamic requirements of advanced applications.

In this chapter, we’ll explore the following topics:

  • Overview of reflection
  • Exploring practical reflection
  • Proxy
