Class PrimitivePatternsPreviewNotes

java.lang.Object
net.jrodolfo.java_evolution.java23.primitive_patterns.PrimitivePatternsPreviewNotes
public class PrimitivePatternsPreviewNotes extends Object
Explains primitive types in patterns, instanceof, and switch as a Java 23 preview feature.

Pattern matching had already improved reference-type checks and deconstruction with instanceof, records, and switch. Primitive values were still less integrated. This preview moves Java toward a more uniform pattern model for both reference and primitive values.
