import java.util.Arrays;


public class Main {

    public static void main(String[] argv) throws Exception {

        String[] arr = new String[] { "1", "abc", "level", null,

                "nowjava.com", "asdf 123" };

        System.out.println(java.util.Arrays.toString(copyArray(arr)));

    }


    public static String[] copyAr
