    String[] extended = new String[5];

    extended[0] = "0";
    extended[1] = "1";
    extended[2] = "2";
    extended[3] = "3";
    extended[4] = "4";

    System.arraycopy(names, 0, extended, 0, names.length);

    System.out.println(Arrays.toString(names));
    System.out.println(Arrays.toString(extended));
