Switch case yield

Why do dis not work

i wont an switch case with yield. But it not compile

userColor is input from user. Data type String

String animalColor = switch (userColor) {
            case "green" -> {
                if (animal.equals("Frog")) yield "Frog";
              
            }
            case "yellow" -> {
                yield "Budgie";
            }
            case "pink" -> {
                yield "Pig";
            }
            case "brown" -> {
                yield "Cow";
            }
            case "black" -> {
                yield "Panther";
            }
            case "white" -> {
                yield "Mouse";
            }
            case "white/black" -> {
                yield animal;
            }
            case "gold" -> {
                yield "Goldfish";
            }
            default -> {
                yield "Unknown";
            }
        };

Her how it look if it frog or orca…

  String animal = "";
        if (Objects.equals(userColor, "green")) {
            System.out.println("Do you mean Frog");
            String isFrog = myObj.nextLine();  // Read user input
            isFrog = isFrog.toLowerCase(Locale.ROOT);
            if (Objects.equals(isFrog, "yes")) {
                animal = "Frog";
            }
        } else if (Objects.equals(userColor, "white/black")) {
            while (true) {
                System.out.println("Do you mean Orca or Zebra");
                String isOrcaOrZebra = myObj.nextLine();  // Read user input
                isOrcaOrZebra = isOrcaOrZebra.toLowerCase(Locale.ROOT);
                if (Objects.equals(isOrcaOrZebra, "orca")) {
                    animal = "Orca";
                    break;
                } else if (Objects.equals(isOrcaOrZebra, "zebra")) {
                    animal = "Zebra";
                    break;
                } else {
                    System.out.println("Type Orca or Zebra");
                }
            }
        }

But that compile easy

All compile but case not.
it says:
Switch expression rule should produce result in all execution paths

thanks for help

>Solution :

You can also so

   String animalColor = switch (userColor) {
            case "green" -> {
                if (animal.equals("Frog")) yield "Frog";
                yield "";
            }
            case "yellow" -> {
                yield "Budgie";
            }
            case "pink" -> {
                yield "Pig";
            }
            case "brown" -> {
                yield "Cow";
            }
            case "black" -> {
                yield "Panther";
            }
            case "white" -> {
                yield "Mouse";
            }
            case "white/black" -> {
                yield animal;
            }
            case "gold" -> {
                yield "Goldfish";
            }
            default -> {
                yield "Unknown";
            }
        };
