Java — Switch

Basic switch

int day = 3;
switch (day) {
    case 1:
        System.out.println("Monday");
        break;
    case 2:
        System.out.println("Tuesday");
        break;
    case 3:
        System.out.println("Wednesday");
        break;
    default:
        System.out.println("Other day");
}

String switch

String fruit = "Apple";
switch (fruit) {
    case "Apple":
        System.out.println("Red");
        break;
    case "Banana":
        System.out.println("Yellow");
        break;
}

Switch expression (Java 14+)

String result = switch (day) {
    case 1 -> "Monday";
    case 2 -> "Tuesday";
    case 3 -> "Wednesday";
    default -> "Other";
};
