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

Question

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 ??

Answer 1

将正确类型的数组传递给List.toArray的另一个重载 ：

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

Answer 2

尝试

String resultData = CMPUtil.getStrategy((Leg [])legs.toArray(new Leg[legs.size()]));

Answer 3

Leg les [] = Legs.toArray（new Leg [legs.length]）;
