原文:分享非常有用的Java程序 (关键代码)(五)---把 Array 转换成 Map

import java.util.Map;

import org.apache.commons.lang.ArrayUtils;

public class Main {

	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"));

}

}
