    Description

      refer to JEP 361 

       

      Example:

      double getPrice(String fruit) {
  switch (fruit) {
    case "Apple":
      return 1.0;
    case "Orange":
      return 1.5;
    case "Mango":
      return 2.0;
    default:
      throw new IllegalArgumentException();
   }
 }

      Can be changed to 

      double getPrice(String fruit) {
    return switch (fruit) {
      case "Apple" -> 1.0;
      case "Orange" -> 1.5;
      case "Mango" -> 2.0;
      default -> throw new IllegalArgumentException();
    };
}
