Writing switch statements

• All switch statements include a default case.

  The default case is the last case in a switch statement. The default case includes a break statement that prevents a fall-through error if another case is added.

• If a case does not have a break statement, the case will fall through (see case A in the following code example).

  Your statement should include a comment in the break statement's place, as you can see in the following example after case A. In this example, if the condition matches case A, both cases A and B execute.

You can write switch statements using the following format:

switch (condition) {
case A :
    // statements
    // falls through
case B :
    // statements
    break;
case Z :
    // statements
    break;
default :
    // statements
    break;
}
