Class SwitchYieldPreviewExamples

java.lang.Object

net.jrodolfo.java_evolution.java13.SwitchYieldPreviewExamples

public class SwitchYieldPreviewExamples
extends Object

Demonstrates yield in switch expressions as a Java 13 preview refinement.

Java 12 previewed switch expressions, but block branches still needed a clear way to produce a value when they contained multiple statements.

Java 13 adjusted the preview by adding yield. It solves the readability problem by making the branch result explicit.
