Java Memory Management: A comprehensive guide to garbage collection and JVM tuning
Improve application performance by tuning, monitoring and profiling both the garbage collector and JVM
Key FeaturesUnderstand the different parts of Java memory and the various garbage collectors so you can select your preferred oneExplore how memory management can help to effectively improve performanceLearn how to spot and avoid memory leaks to enhance application performanceBook DescriptionUnderstanding 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 learnUnderstand the schematics of debugging and how to design the application to perform wellDiscover how garbage collectors workDistinguish between various garbage collector implementationsIdentify the metrics required for analyzing application performanceConfigure and monitor JVM memory managementIdentify and solve memory leaksWho this book is forThis book is for all levels of Java professionals, regardless of whether you're a junior or senior developer, a DevOps engineer, a tester, or the system admin of a Java application. If you currently don't have in-depth knowledge of Java memory, garbage collection, and/or JVM tuning, then this book will help you to take your Java skills to the next level.

A fundamental guide for anyone working with a memory intensive application in Java
It's not going very deep but it explains thé basics super clearly with great explanations and illustrations
It's also pretty short

The book I wish I had read it when I had less experience in Java.
Book is simple and concise. It provides basic knowledge about what Garbage Collector is and how it works. An explanation of different GC algorithms across GC implementations is very clear. Also, author provides a bunch of JVM flags to tune GC a little bit. And what I really like is the author advice – when you want to tune GC be sure that you don't have anything else to tune but GC.
I can definitely recommend this book to those who just started the path of Java developer (0.5-1 year experience).

Perfecta introducción
Da contextualizacion, demuestra los casos con ejemplos, muy claro y preciso, va acorde a lo establecido para Java, y da las herramientas necesarias para replicar los casos
