The Java software development kit (JDK), version 17 or higher, is necessary to use with Eclipse and Spring Boot 3. In this book, we are using the Windows operating system, but all tools are available for Linux and macOS as well. You can get the JDK installation package from Oracle (https://www.oracle.com/java/technologies/downloads/) or you can use OpenJDK versions as well. You can check the version of the installed Java SDK by typing the
java –version command in your terminal.
