Scala error - error: not found: type -

-

i java developer trying learn class creation in scala.

i create 2 separate scala files. 1 file contains trait. second file extends trait , defines method.

cola.scala contains trait.

trait cola {         def fizz(): string }

pepsi.scala has class tries extend trait.

class pepsi extends cola {         override def fizz():string = "1 sugar" }  var p = new pepsi println( " p = " + p.fizz )

when excecute "scala pepsi.scala" following error message:

 error: not found: type cola class pepsi extends cola

both files in same folder.

please how resolve this? using scala 2.8 not using editor forced scratch. improve knowledge computers.

scala doesn't require put of traits , classes eponymous (that is, named same class) files. can put of in 1 file , work. or can specify both files on command line: scala not automatically cola in cola.scala.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
