What’s New in IntelliJ IDEA 2022.1 Beta 2 for Java Developers?
IntelliJ IDEA 2022.1 Beta 2 introduces Java 18 support, new @snippet Javadoc tags, enhanced switch pattern‑matching, updated JUnit 5 annotations, and editor inspections that alert developers to formatting mismatches, helping Java developers stay up‑to‑date with the latest language and tooling features.
IntelliJ IDEA 2022.1 Beta 2 has been released, bringing several important updates for Java developers.
Java enhancements
With the official release of Java 18, IDEA now supports new features such as the @snippet tag for embedding example code in Javadoc via the standard Doclet @Snipket tag.
The switch expression pattern‑matching introduced in JDK 17 has also been updated and is now fully supported.
Other updates include making UTF‑8 the default charset in JDK 18 and removing warnings for non‑static inner classes that do not capture this.
JUnit 5 enhancements
IDEA adds support for new JUnit 5.7 annotations, including @EnabledIf / @DisabledIf, @NullSource / @EmptySource, and @TempDir.
Editor optimizations
A new “Incorrect formatting” inspection notifies developers when a file’s current format does not match the configured code style, with options to enable or disable it.
