Digging into the JVM's Underside
 |
Description
Book Introduction
“An exciting adventure deep into the Java Virtual Machine.”
Back when programming was primarily done using C and C++, the difficult memory management and platform portability issues were a significant burden for developers.
In such a situation, Java, which appeared with the slogan “Write once, run anywhere,” was considered a groundbreaking language.
And the technology that laid the foundation for making that slogan a reality was the Java Virtual Machine (JVM). While the JVM seemed to grant developers the gift of automatic memory management and platform independence, it came at a price: poor performance and out-of-memory errors.
And the reality is that even today we are not free from such problems.
To solve these problems, we need to understand the core principles of how the JVM handles complex, low-level problems.
『Understanding the JVM』 examines the core operating principles of automatic memory management, execution subsystem, compilation, and concurrency, which are the four main topics of the JVM, and introduces how these principles affect the execution of software actually written in Java and how the JVM operating mechanism can be applied to problems encountered in the development field.
Developers who wish to build robust systems using Java, which has grown from the days of creating small applets to a language that supports a corner of the Internet world, will find many ideas and inspiration in this book.
