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"));     
}   
}
