Working with Conditional Statements
• To test a single condition, use the construction
if (
condition
) {
commands
}
where
condition
is a Boolean expression and
commands
is a command block run if
the conditional expression is true.
• To test between two conditions, use the following construction:
if (
condition
) {
commands if condition is true
} else {
commands if not true
}
• To test multiple conditions, use the construction
if (
condition 1
) {
first command block
} else if (
condition 2
) {
second command block
} else if (
condition 3
) {
third command block
…
} else {
default command block
}
where
condition 1
,
condition 2
,
condition 3
, and so on are the different condi-
tions to be tested. If no conditional expressions return the value
true
, the
default
command block
is run.

ing task involves writing out the table cells containing the calendar days so that they're
organized into separate rows. You'll complete the calendar app in the next section.
