Tasks:

1. Basic switch.

Update the program so that it prints "default", using switch statement:

 public class BasicSwitch {
    public static void main(String[] args) {
        int a = 20;
        switch (a) {
            default:
                System.out.println("default");
                break;
            case 7:
                System.out.println("seven");
                break;
            case 10:
                System.out.println("ten");
                break;
            case 20:
                System.out.println("twenty");
                break;
        }
    }
}

2. Basic switch breaks.

Update the program so that it prints "twenty", using switch statement:

 public class BasicSwitch {
    public static void main(String[] args) {
        int a = 20;
        switch (a) {
            default:
                System.out.println("default");
            case 7:
                System.out.println("seven");
            case 10:
                System.out.println("ten");
            case 20:
                System.out.println("twenty");
        }
    }
}

3. Switch days in month printer.

Rewrite 7. Days in month printer. from task 3 with switch :

 public class SwitchDaysInMonthPrinter {
    public void amountOfDays(int month) {
    }
 }

4. Range numbers printer.

Create that will be printing if number is between 1 and 5("number is between 1 and 5"), 6 and 10("number is between 6 and 10") or "out of range" using switch statement. Number to be defined will be passed to method arguments:

    public class RangeNumbersPrinter {
         public void printRange(int number) {
         }
    }

5. Leap year printer.

Create a program to check whether a year is a leap year or not("leap" if true otherwise "not leap"). Year will be passed as argument in method parameter:

    public class LeapYearPrinter {
         public void isLeapYear(int year) {
         }
    }

So what should happen if we do not set break to any of the statements? (self exploring section).
