    String [] countriesArray = countryList.toArray(new String[countryList.size()]);
    

    I have assumed that your country List name is countryList.

    So to convert ArrayList of any class into array use following code. Convert T into the class whose arrays you want to create.

    List list = new ArrayList();    
    T [] countries = list.toArray(new T[list.size()]);
