Improve application performance by tuning, monitoring and profiling both the garbage collector and JVM

Key Features
Understand the different parts of Java memory and the various garbage collectors so you can select your preferred one
Explore how memory management can help to effectively improve performance
Learn how to spot and avoid memory leaks to enhance application performance
Book Description
Understanding how Java organizes memory is important for every Java professional, but this particular topic is a common knowledge gap for many software professionals. Having in-depth knowledge of memory functioning and management is incredibly useful in writing and analyzing code, as well as debugging memory problems. In fact, it can be just the knowledge you need to level up your skills and career.

In this book, you'll start by working through the basics of Java memory. After that, you'll dive into the different segments individually. You'll explore the stack, the heap, and the Metaspace. Next, you'll be ready to delve into JVM standard garbage collectors. The book will also show you how to tune, monitor and profile JVM memory management. Later chapters will guide you on how to avoid and spot memory leaks.

By the end of this book, you'll have understood how Java manages memory and how to customize it for the benefit of your applications.

What you will learn
Understand the schematics of debugging and how to design the application to perform well
Discover how garbage collectors work
Distinguish between various garbage collector implementations
Identify the metrics required for analyzing application performance
