Book review: JAVA HOW LOW CAN YOU GO

Source: Dev.to

Overview

I liked JAVA HOW LOW CAN YOU GO: Low‑latency design for RFQ and high‑frequency trading (covering Java 24+ and beyond) because it goes beyond normal Java development and focuses on areas that really matter in low‑latency systems.

Key Topics

• Performance and concurrency
• Garbage collection and memory handling
• Networking and system‑level design
• Connection to trading technology, including:
  • RFQ platforms
  • Market making
  • Exchange matching
  • Order routing

These topics are presented in a practical context rather than as purely theoretical concepts.

Audience

The book is most helpful for Java developers who already know the basics and want to understand how high‑performance systems are built. It is also a strong resource for interview preparation, especially for roles in:

• Banks
• Hedge funds
• Electronic trading teams

Low‑latency concepts frequently appear in these interviews.

Conclusion

Overall, this is a practical book for developers who want to move closer to performance‑focused Java and real trading architecture. It feels more job‑relevant than many general Java books and is one of the best resources for interview preparation.
