Java switch expression

Question

I dont get this @_@??? it's not working

int dayType=switch(day){ //illegal start of expression switch
case 1, 2, 3, 4, 5 -> "working day";
case 6, 7 -> "weekend";
default -> "invalid day";
};

Answer 1

The return type of your switch expression doesn't match the expected type. dayType is an int, but a String is returned.

int day = 3;
String dayType = switch(day) {
case 1, 2, 3, 4, 5 -> "working day";
case 6, 7 -> "weekend";
default -> "invalid day";
};
System.out.println(dayType);
