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.

Proxy

Dynamic proxies in Java are indispensable tools that enable the creation of objects at runtime, implementing one or more interfaces, and intercepting method invocations. The MapperRepository class introduces us to the profound utility of dynamic proxies, where their application becomes paramount in seamlessly switching between entities and their corresponding map representations.

Dynamic proxies stand as veritable champions in the arsenal of Java’s runtime capabilities, offering a trove of advantages that elevate code’s adaptability, flexibility, and conciseness. Their inherent adaptability allows for creating proxy instances on the fly, accommodating diverse interfaces at runtime, and facilitating seamless integration in scenarios where object structures are only known at runtime. The ability to intercept method invocations empowers dynamic proxies to inject custom logic seamlessly, enhancing functionalities without compromising the integrity of core operations...
