  public static void main(String[] args) {

    String[][] countries = { { "United States", "New York" }, { "United Kingdom", "London" },

        { "Netherland", "Amsterdam" }, { "Japan", "Tokyo" }, { "France", "Paris" } };

 

    Map countryCapitals = ArrayUtils.toMap(countries);

 

    System.out.println("Capital of Japan is " + countryCapitals.get("Japan"));

    System.out.println("Capital of France is " + countryCapitals.get("France"));
