As3 defines classes in the package

In as3, you can define other classes outside the package of a class and reference the package class in this class:

Package com. Custom. utils
{
Public class tfunction
{
Public var minus: function;
Public static const M: Int = 10;
Public const N: Int = 20;

Public Function tfunction ()
{
VaR test1: test1 = new test1 ();
VaR Test2: Test2 = new Test2 ();
}

Public var alert: function = function (M: int, N: INT): void
{
Trace ("tfunction is create:" + (m + n ));
}

Public Function show (... ARGs ):*
{
If (ARGs. Length = 2)
{
Trace ("tfunction minus show:" + (ARGs [0]-ARGs [1]);
}
Else if (ARGs. Length = 3)
{
Trace ("tfunction chongzai:" + (ARGs [0] + ARGs [1] + ARGs [2]);
}
}
}
}

Class test1 {
Public Function test1 (){
Trace ("now is Bao nei Lei test1 ");
}
}

Class Test2 {
Public Function Test2 (){
Trace ("now is Bao nei Lei Test2 ");
}
}
