In this code, you create a string called

method of the Date class to get the current hour. Then you can use the
getHours()
statement to trace information to the Output panel, based on the number

that returns. For more information, see the comments in the previous code snippet.
Using a switch statement
The statement creates a branching structure for ActionScript statements. Similar to
switch
the statement, the
if
condition returns a value of
When you use a
switch
statements in that case block and jump to the first statement that follows the enclosing
statement. If a case block doesn't contain a break statement, a condition called "fall
switch
through" occurs. In this situation, the following case statement also executes until a break
statement is encountered or the
following example, where the first case statement doesn't contain a break statement and
therefore both of the code blocks for the first two cases (A and B) execute.
All statements should include a
switch
last case on a
switch
through error if another case is added. For example, if the condition in the following example
evaluates to A, both the statements for case A and B execute, because case A lacks a
statement. When a case falls through, it does not have a break statement, but includes a
comment in the
break
case A. Use the following format when you write
switch (condition) {
case A :
// statements
// falls through
case B :
// statements
break;
case Z :
// statements
break;
default :
// statements
break;
