This project provides a set of Java code examples illustrating the subset of new language features and APIs that were introduced in Java 11 that are of interest to developers
The examples are implemented as a set of easy to run tests, using JUnit (5).
For a broader look at the new features in JDK 11 that are of most interest to developers see my blog post Java 11 – New Features, Code Examples & Support.
The source code for the examples can be found in the src/test/java folder.
An explanation of the showcased language features, along with guidance on their usage, can be found in the Javadoc of each of the code examples. (See the commands for generating Javadoc below).
You will need to install a Java 11 JDK.
Support is provided for building and running the project using either Gradle or Maven as described in the sections below.
The minimum required version of Gradle will be installed if you execute the build using the supplied Gradle wrapper script (./gradlew).
To compile and run all the example tests, enter the following command in the project’s root folder:
./gradlew clean test
To generate the Javadoc, use the following command:
./gradlew clean javadocTests
The generated Javadoc can be found in the standard location for a Gradle project - build/docs/javadoc/index.html.
For more details of Gradle build support see build.gradle in the project’s root folder.
The minimum required version of Maven will be installed if you execute the build using the supplied Maven wrapper script (./mvnw).
To compile and run all the example tests, enter the following command in the project’s root folder:
./mvnw clean test
To generate the Javadoc, use the following command:
./mvnw javadoc:test-javadoc
The generated Javadoc can be found in the standard location for a Maven project - target/site/testapidocs/index.html.
For more details of Maven build support see pom.xml in the project’s root folder.
