Java Switch Statement

switch selects one of many blocks to run, based on the value of an expression. It works with int, char, String, enums and wrapper types.

Java

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");
}

Wednesday

Fall-throughWithout break, execution continues into the next case.

Java

String d = "SUN";
String type = switch (d) {
    case "SAT", "SUN" -> "Weekend";
    default -> "Weekday";
};
