Hi.

I have a method in class with 6 parameters. 2 of them are float types, one is string. The other 3 are classes. Not all the time I pass the 6 parameters, like this:

particula.add(10,10,"brilho_moeda",Null,moeda)

And when I try to pass one of the classes as Null or do not pass at all I got this error:

I/[Monkey]( 1907): Monkey Runtime Error : java.lang.NullPointerException
E/AndroidRuntime( 1907): FATAL EXCEPTION: main
E/AndroidRuntime( 1907): java.lang.NullPointerException

In other situation, I pass only the 3 first parameters (Float,Float,String) and it works fine, like this:

particula.add(10,10,"neve")

How do I handle this?

Method:

Method add(px:Float,py:Float,ptipo:String,pbalao:Baloes=Null,pmoeda:Moedas=Null,pbalao2:Baloes=Null)

Well you don't get this because you pass a Null as parameter but you get a null pointer exception because you obviously try to access this instance then in your method.
