==Initialize the index variable to Array .length -1 and loop until it reaches 0 by decrementing the index variable==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var letters:Array = ["a", "b", "c", "d", "a", "b", "c", "d"];

var match:String = "b";

for (var i:int = letters.length - 1; i >= 0; i--) {
if (letters[i] == match) {
trace("Element with index " + i +
" found to match " + match);
break;
}
}
}
}
}
</source>

==Looping Through an Array==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){

var letters:Array = ["a", "b", "c"];
for (var i:int = 0; i < letters.length; i++) {
trace("Element " + i + ": " + letters[i]);
}
}
}
}
</source>

==loop through the elements of the array starting with the last element and working backward==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){

var aEmployees:Array = ["A", "P", "C", "H"];
for(var i:Number = aEmployees.length - 1; i >= 0; i--) {
trace(aEmployees[i]);
}
}
}
}
//H
//C
//P
//A
</source>

==Searching for Matching Elements in an Array==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var letters:Array = ["a", "b", "c", "d", "a", "b", "c", "d"];

var match:String = "b";

for (var i:int = 0; i < letters.length; i++) {
if (letters[i] == match) {
trace("Element with index " + i + " found to match " + match);
break;
}
}
}
}
}
</source>

==Use a for statement that loops backward from Array. length -1 to 0, decrementing by one each time.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var letters:Array = ["a", "b", "c"];

for (var i:int = letters.length - 1; i >= 0; i--){
trace("Element " + i + ": " + letters[i]);
}
}
}
}
