Branching Statements
switch (expression) {
case value1:
case value2:
Command;
break;
case value3:
case value4;
Command;
break;
default:
Command;
}
The preceding SWITCH statement is equivalent to the following IF-ELSEIF
statement in C++:
if (expression = value1) || (expression = value2) {
Command;
}
else if (expression = value3) || (expression = value4) {
Command;
}
else {
Command;
}
One main difference between C# and Java is the way each language handles
fall-through, where multiple CASE statements can run if a break command
isn’t inserted into each one. Consider the following SWITCH statement in
Java, which allows fall-through:
switch (age) {
case 17:
case 18:
case 19;
case 20;
System.out.println(“You’re too young to drink.”);
case 21:
System.out.println(“You’re old enough to drink.”);
}
In this example, the SWITCH statement will print the following if the value of
age is 17, 18, 19, or 20:
You’re too young to drink.
You’re old enough to drink.
