How to convert an Object[] type to Userdefined array type

I am creating the Leg Objects this way 

List<Leg> legs = new ArrayList<Leg>(legdata.length);

I need to pass this legs to an method with the below signature as shown :

 public static String getStrategy(Leg[] leg)

when i did the below way i am getting an error .

String resultData = CMPUtil.getStrategy(legs.toArray());

Also tried this way 

Leg les[] = (Leg)legs.toArray();  ( It says cannot cast from Object to Leg)

could anybody please let me know , how to resolve this ??

Pass in an array of the right type to the other overload of List.toArray:

Leg[] legsArray = legs.toArray(new Leg[0]); // Or new Leg[legs.size()]
