🚀 Modern Java Switch Expressions (Arrow Syntax & yield)

Introduction

Introduced in Java 14, Switch Expressions modernize branching syntax: they eliminate accidental fallthrough, allow switch to return a value directly, and use clean arrow syntax (->).

🎯 Arrow Syntax (`->`) Without `break`

1public class ModernSwitchDemo {
  public static void main(String[] args) {
      int dayOfWeek = 3;
4 
      // Switch returning a value directly!
      String dayType = switch (dayOfWeek) {
          case 1, 2, 3, 4, 5 -> "Weekday (Classes Active)";
          case 6, 7 -> "Weekend (Lab Sessions Only)";
          default -> "Invalid Day Number";
      };
11 
      System.out.println("Day Status: " + dayType);
  }
14}

🌾 The `yield` Statement for Multi-Line Blocks

When a switch branch requires multiple statements before yielding a value, use yield:
