Switch vs When example 3

switch_ex_3.java

// execute all label expression that is valid
int day = 3;
switch(day){
    case 1:
    case 2:
    case 3:
        System.out.println("Wednesday is workday");
    case 4:
    case 5:
        System.out.println("Work day");
        break;
    case 6:
    case 7:
        System.out.println("Weekend");
        break;
}
// prints "Wednesday is workday"
//         "Work day"

when_ex_3.kt

// execute the first label expression that is valid
// prints different result depending on order

val day = 3;
when (day) {
    1, 2, 3, 4, 5 -> println("Work day")
    3 -> println("Wednesday is workday")
    6, 7 -> println("Weekend");
}

//outputs: Work day

// lets change the order of the labels
when (day) {
    3 -> println("Wednesday is workday")
    1, 2, 3, 4, 5 -> println("Work day")
    6, 7 -> println("Weekend");
}
//outputs: Wednesday is workday
