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.

Why do we have frameworks?

We’ll explore the underlying reasons for the prevalence and evolution of Java frameworks in software development. Adopting frameworks aligns seamlessly with established software development practices, arising organically as a response to the perpetual quest for efficiency, reliability, and scalability. Developers, faced with the challenges of crafting intricate and feature-rich applications, find in frameworks a strategic ally that provides a structured and standardized foundation, facilitating the reuse of components and streamlining development processes.

A key motivation behind the widespread use of frameworks is their capacity to address challenges related to redundant code and duplicated bugs. By encapsulating best practices, design patterns, and common functionalities, frameworks empower developers to concentrate on distinctive aspects of their applications, fostering code efficiency and reducing the likelihood of errors. It expedites development...
