About the Book
Java 21 is released. Check out my new book From Java 17 to 21 to upgrade to Java 21.
Java 17 is a LTS version of Java. Java 17 should be the next version to upgrade if you are using Java 8 or Java 11. It is expected that users of Java 8 and 11 will gradually migrate to Java 17. Spring 6 is released with requirement of JDK 17+. You must upgrade to Java 17 to use Spring 6.
This book covers major changes from Java 11 to Java 17. Below is a list of these features:
- Records

- Pattern matching
- Text blocks
- JFR event streaming, JVM constants API, hidden classes
- Changes to Java standard libraries
- New garbage collectors

If you are using Java 11 and planning to upgrade to Java 17, this book can provide you with a valuable reference.
