Practice mode — check each part and get hints as you go.

Task

Fill in daysInMonth using a switch expression with a grouped label: months 4, 6, 9, 11 have 30 days, month 2 has 28, all others 31.

Several values share one branch when listed with commas. The program prints 30, 28, 31. (Ignore leap years.)

Your solution

public class Main {

    public static int daysInMonth(int month) {
        // switch expression with a grouped label for the 30-day months

    }

    public static void main(String[] args) {
        System.out.println(daysInMonth(6));
        System.out.println(daysInMonth(2));
        System.out.println(daysInMonth(12));
    }
}
