What led the author to write this book: Miroslav Wengner: The Interview
All of the code is organized into folders. For example, Chapter02.
The code will look like the following:
public class Vehicle
Following is what you need for this book: If you are an intermediate-level Java developer or software architect looking to learn the practical implementation of software design patterns in Java, then this book is for you. No prior knowledge of design patterns is required, but an understanding of Java programming is necessary.
With the following software and hardware list you can run all code files present in the book (Chapter 1-7).
| Chapter | Software required | OS required |
|---|---|---|
| 1 | Java Development Kit 17+ | Windows, Mac OS X, and Linux (Any) |
| 1 | Recommended IDE VSCode 1.73.1+ | Windows, Mac OS X, and Linux (Any) |
| 1 | A text editor or IDE | Windows, Mac OS X, and Linux (Any) |
We also provide a PDF file that has color images of the screenshots/diagrams used in this book. Click here to download it.
Java Development Kit 17+ is required to run the book's examples. To check if it is available on your system, execute the following commands:
$ java -version # Expected output: openjdk version "17" 2021-09-14 OpenJDK Runtime Environment (build 17+35-2724) OpenJDK 64-Bit Server VM (build 17+35-2724, mixed mode, sharing)
In case the JDK is not installed, feel free to visit the following links for help:
The project contains several *.jfr recordings. The file-name refers to the image that was created from this recording. Java Mission Control version 8.2 was used for image creation purposes. *.jfr files can be opened in the Java Mission Control application, which can be downloaded from the links below.
# Starting the JavaFlightRecorder for the patterns # Recordings are done on Java 17 $ java -XX:StartFlightRecording=filename=PATTERN_NAME_MAIN>.jfr,dumponexit=true,settings=profile MAIN_CLASS>
