==Adding Static Methods to a Class==



<source lang="java">

/*
static publicPrivateModifier function methodName([paramList]):datatype {
// Method code goes here.
}
*/

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
Car.statcF();
}
}
}
class Car{
static public function statcF(){
trace("static");

}
}
</source>

==A simple example of a method declaration using parameters==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var averageValue:Number = average(5, 11);
}
private function average(a:Number, b:Number):Number {
return (a + b)/2;
}
}
}
</source>

==Change member variable value in member method==



<source lang="java">

class Car {

public var speed:Number;
public var direction:String;

public var onSpeedChange:Function;
public var onDirectionChange:Function;
public function Car(speed,direction) {
this.speed = speed;
this.direction = direction;
}
public function increaseSpeed() {
this.speed += 10;
this.onSpeedChange();
}
public function setDirection(direction) {
this.direction = direction;
this.onDirectionChange();
}

}
</source>

==Create a method and then call it by name==



<source lang="java">

package {
import flash.display.Sprite;
public class Main extends Sprite
{
public function Main( ) {
for(var i:int=0;i<10;i++) {
drawLine( );
}
}

private function drawLine( ):void {
graphics.lineStyle(1, Math.random( ) * 0xffffff, 1);
graphics.moveTo(Math.random( ) * 400, Math.random( ) * 400);
graphics.lineTo(Math.random( ) * 400, Math.random( ) * 400);
}
}
}
</source>

==Defining Methods for a Class==



<source lang="java">

/*
The syntax for a public method is:
public function methodName([parameterList]):datatype {
// Method code goes here.
}
The syntax for a private method is almost identical:
private function methodName([parameterList]):datatype {
// Method code goes here.
}
*/
package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var crTest:Car = new Car();

crTest.drive(true); // Displays: Car is driving.
crTest.drive(false); // Displays: Car is stopped.
}
}
}
class Car {
public function drive(bStart:Boolean):void {
if(bStart) {
trace("Car is driving.");
}
else {
trace("Car is stopped.");
}
}
}
</source>
