int

;
2. Run the loop until we reach the beginning of the array (including
position 0)
i >=
0
;
3. Decrease the value of the index at the end of each loop iteration
i--
char
[] myArray = {
'A'
,
'B'
,
'C'
,
'D'
};
for
(
int
i = myArray.

; i >=
0
; i--) {
System.
out
.println(myArray[i]);
}
Try to read through that yourself a few times to understand what each part
is doing. Then I’ll spill the beans. I hate beans.
Here’s how what we’re asking Java to do in English…
1. Create an array with 4 elements, A B C D.
2. Create a variable i (the index) and set it equal to 3 to start.
3. Specify that the loop should keep going as long as i is greater or
equal to 0.
4. Specify that at the end of each loop, we should decrease the index
by 1.
And here’s how it actually runs, step by step. If you’re confused right now,
this part should help.

[] myArray = {
'A'

0

System.

.println(myArray[i]);
}
1. Set i to 3. This is greater than or equal to 0. Run code inside loop
(Print ‘D’). Decrease i by 1.
2. i is now 2. This is greater than or equal to 0. Run code inside loop
(Print ‘C’). Decrease i by 1.
3. i is now 1. This is greater than or equal to 0. Run code inside loop
(Print ‘B’).. Decrease i by 1.
4. i is now 0. This is greater than or equal to 0. Run code inside loop
(Print ‘a’).. Decrease i by 1.
5. i is now -1. This is not greater than or equal to 0. Loop is
