How To Use switch In Modern Java

A practical guide to using switch in modern Java (14+), covering three orthogonal decisions: colon vs arrow syntax, statement vs expression form, and labels vs patterns. Arrow syntax is recommended over colons to avoid fall-through issues. Switch expressions are preferred when both forms work, due to exhaustiveness checks and clearer logical flow. Labels vs patterns is determined by the problem: use labels for value comparisons and patterns for structural checks. Also previews upcoming pattern matching features in Java 19, including when clauses and how switch may eventually replace if-else-if chains.
