Look inside
Effectively reading and understanding existing code is a developer’s superpower. In this book, you’ll master techniques for code profiling, advanced debugging, and log evaluation to find and fix bugs and performance problems.

In How To Read Java: Understanding, debugging, and optimizing JVM applications you will learn how to:

  • Determine what code does the first time you see it
  • Expose code logic problems
  • Evaluate heap dumps to find memory leaks
  • Monitor CPU consumption to optimize execution
  • Use thread dumps to find and solve deadlocks
  • Easily follow a service-oriented or microservices system
  • Properly use logging to better understand Java app execution
  • Use Java debuggers efficiently

How To Read Java: Understanding, debugging, and optimizing JVM applications teaches code investigation techniques that will help you understand how Java apps work, optimize them, and fix the bugs that break them. You’ll go from the basics of debugging to advanced methods for locating problems in microservices architectures. Each new technique is explained with lively illustrations and engaging real-world examples.

about the technology

Tasks like searching for bugs, working through messy legacy code, and analyzing an application’s readiness to support new features consume a lot of developer time. In fact, most developers spend more time trying to read and understand code than they do writing it! In this unique guide, you’ll learn techniques like resolving deadlocks by examining thread dumps and locating memory leaks by inspecting the heap that will radically improve your efficiency when working with existing code in JVM languages like Java, Scala, and Kotlin.

about the book

How To Read Java: Understanding, debugging, and optimizing JVM applications teaches you how to better understand Java application code. It’s filled with code investigation techniques for tricky issues like uncovering glitches in code logic or locating intermittent runtime problems. Armed with these tools and practices you’ll save time whenever you need to identify performance issues, understand dependencies, discover the root cause of crashes, or interpret unexpected results. Whether you’re a senior software engineer or you’re just getting started, this invaluable guide will help you in the fundamental task of understanding how your applications work.
