1.把 二维数组(Array)转换成 Map

import java.util.Map;   
import org.apache.commons.lang.ArrayUtils;   
	   
public class ArrayToMap {   
	  public static void main(String[] args) {   
	    String[][] countries = { { "United States", "New York" }, { "United Kingdom", "London" },   
	        { "Netherland", "Amsterdam" }, { "Japan", "Tokyo" }, { "France", "Paris" } };   
	     //循环遍历数组中的每个元素  
	    for (int i = 0; i < countries.length; i++) {      
            for (int j = 0; j < countries[i].length; j++) {               	
                System.out.print((String)countries[i][j]);
                System.out.print(" ");//输出空格
                //将数组中的元素输出  
            }  
            System.out.println();//回车，转入下一行                              
        }  	    
	    
	    Map countryCapitals = ArrayUtils.toMap(countries); //ArrayUtils数组工具类的使用！
	   
	    System.out.println("Capital of Japan is " + countryCapitals.get("Japan"));   
	    System.out.println("Capital of France is " + countryCapitals.get("France"));   
	  }   
}

2.输出结果：
