==A list of parameters, each of which is a new value to insert into a new element in the array==



<source lang="java">

package{

public class Main extends Sprite{
public function Main(){
// Create a new array with zero elements.
var aEmployees:Array = new Array("A", "P", "C","H");

trace(aEmployees);
}
}
}
</source>

==Arrays in ActionScript can contain any type of object:==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var time:Date = new Date();
var currentTemp:Number = 56;
var currentConditions:String = "Light Showers";
var weatherReport:Array = new Array(time, currentTemp, currentConditions);
trace(weatherReport);
}
}
}
</source>

==A single parameter specifying the number of elements creates a new array with the specified number of elements.==



<source lang="java">

package{

public class Main extends Sprite{
public function Main(){
// Create a new array with four elements.
var aEmployees:Array = new Array(4);

trace(aEmployees);
}
}
}
</source>

==Converting Arrays to Strings: by default, arrays display a comma-separated list of values.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var names:Array = ["Jenene", "Josh", "Jac"];
trace(names); // Displays: Jenene,Josh,Jac
}
}
}
</source>

==Creating Arrays: No parameters constructor creates a new array with zero elements.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
// Create a new array with zero elements.
var aEmployees:Array = new Array();
trace(aEmployees);
}
}
}
</source>

==Delete elements and insert new elements at the same time==



<source lang="java">

package{

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

var letters:Array = ["a", "b", "c", "d"];

letters.splice(1, 2, "r", "s", "t");

for (var i:int = 0; i < letters.length; i++) {
trace(letters[i]);
}
}
}
}
</source>

==Inserting Elements in the Middle of an Array==



<source lang="java">

package{

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

letters.splice(1, 0, "r", "s", "t");

for (var i:int = 0; i < letters.length; i++) {
trace(letters[i]);
}
}
}
}
a
r
s
t
b
c
d
</source>

==Is element in an array undefined==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var numbers:Array = new Array(4, 10);
numbers[4] = 1;
trace(numbers);
for(var i:int = 0; i < numbers.length; i++) {
if(numbers[i] == undefined) {
numbers.splice(i, 1);
i--;
}
}
trace(numbers);
}
}
}
// 4,10,,,1
// 4,10,1
</source>

==Set an element with an index that doesn"t exist==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var letters:Array = ["a", "b", "c"];
letters[5] = "f";

trace(letters);
}
}
}
</source>

==Use array literal notation as an alternative to the first variation of the constructor.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var aEmployees:Array = [];

trace(aEmployees);
}
}
}
</source>

==Within the square brackets you can provide a list of elements to add to the array==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var aEmployees:Array = ["A", "P", "C", "H"];

trace(aEmployees);
}
}
