if
(numGiraffes >
500
) {
System.
out
.println(
"Please send help."
);
}
That line of code that prints to the system only happens if we have more
than 500 giraffes.
Another example:
Scanner userInputReader =
new
Scanner(System.
in
);
int
userInputNumGiraffes = userInputReader.nextInt();
if
(userInputNumGiraffes <=
0
) {
System.
out
.println(
"Where they at?"
);
}
That line of code prints to the system only if the user typed in a 0. Or a
negative number. I’m going to skip explaining how to 
get input via a
Scanner
 , OK? Really, really dull stuff.
Anyway, does the 
if
part make sense? It’s pretty similar to English, really. 
If
this, do that.

Now, what if we also want to do something when the user types in an actual
value? If you remember the comparison operators, you could add something
like this below that conditional:
if
(userInputNumGiraffes <=
0
) {
System.
out
.println(
"Where they at?"
);
}
if
(userInputNumGiraffes >
0
) {
System.
out
.println(
"I shall add them at once."
);
}
Two 
if
statements, back-to-back. Could work, right? But that’s stupid. Why
check the value of 
userInputNumGiraffes
in two places? Don’t do that.
Instead, add an else block to the original 
if
statement, as follows:
if
(userInputNumGiraffes <=
0
) {
System.
