For example,
Write a Java program that demonstrates the concept of fall through in a switch statement.
Program 2
The program should evaluate the value of a variable day and print the corresponding day of
the week.
• If the value of day is 1, print "Monday".
• If the value of day is 2, print "Tuesday".
• If the value of day is 3, print "Wednesday" and break the switch statement.
• If the value of day is 4, print "Thursday".
• If the value of day doesn't match any case, print "Invalid day".
• Ensure that there is no break statement after the cases for 1 and 2, to demonstrate fall
through behaviour.

1 public class FallThroughExample {
2 public static void main(String[] args) {
3 int day = 2;

4 switch (day) {
5 case 1:
6 System.out.println("Monday");

7 // Fall through, no break
8 case 2:
9 System.out.println("Tuesday");

10 // Fall through, no break
11 case 3:
12 System.out.println("Wednesday");

13 break;
14 case 4:
15 System.out.println("Thursday");

16 break;
17 default:

18 System.out.println("Invalid day");
19 }
20 }
21 }

The output of the preceding program is as follows:
