SwitchDemoFallThrough.java
class SwitchDemoFallThrough
{
public static void main(String[] args)
{

/*
* Each break statement terminates the enclosing switch statement.
* Control flow continues with the first statement following the switch
* block. The break statements are necessary because without them,
* statements in switch blocks fall through: All statements after the
* matching case label are executed in sequence, regardless of the
* expression of subsequent case labels, until a break statement is
* encountered.
*/

int month = 10;
String monthValue;
switch (month)
{
case 1:
monthValue = "January";
System.out.println("monthValue : " + monthValue);

case 2:
monthValue = "February";
System.out.println("monthValue : " + monthValue);
case 3:
monthValue = "March";
System.out.println("monthValue : " + monthValue);

case 4:
monthValue = "April";
System.out.println("monthValue : " + monthValue);

case 5:
monthValue = "May";
System.out.println("monthValue : " + monthValue);

case 6:
monthValue = "June";
System.out.println("monthValue : " + monthValue);

case 7:
monthValue = "July";
System.out.println("monthValue : " + monthValue);

case 8:
monthValue = "August";
System.out.println("monthValue : " + monthValue);

case 9:
monthValue = "September";
System.out.println("monthValue : " + monthValue);

case 10:
monthValue = "October";
System.out.println("monthValue : " + monthValue);

case 11:
monthValue = "November";
System.out.println("monthValue : " + monthValue);

case 12:
monthValue = "December";
System.out.println("monthValue : " + monthValue);

default:
monthValue = "Invalid month";
System.out.println("monthValue : " + monthValue);

}
System.out.println("Month is : " + monthValue);
}
}
Output
monthValue : October
monthValue : November
monthValue : December
monthValue : Invalid month
Month is : Invalid month
