convert Map Values into String Array

Question

Here ,I am trying to convert map values into String array but i am getting

Error

ERROR/AndroidRuntime(23588): Caused by: java.lang.ClassCastException: [Ljava.lang.Object;

Code

Map<String,String> contactNumber = new HashMap<String,String>(); 

String results [] =  (String[]) contactNumber.values().toArray();

Answer 1

You should use the other toArray(T[] a) method.

String[] result = contactNumber.values().toArray(new String[0]);

Answer 2

You can't perform the cast like this. Instead, call the other toArray method:

String[] result = contactNumber.values().toArray(new String[0]);
