How to do an array of hashmaps?

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;


public class testHashes {
    public static void main(String args[]){
        Map<String,String> myMap1 = new HashMap<String, String>();

        List<Map<String , String>> myMap  = new ArrayList<Map<String,String>>();

        myMap1.put("URL", "Val0");
        myMap1.put("CRC", "Vla1");
        myMap1.put("SIZE", "Val2");
        myMap1.put("PROGRESS", "Val3");

        myMap.add(0,myMap1);
        myMap.add(1,myMap1);

        for (Map<String, String> map : myMap) {
            System.out.println(map.get("URL"));
                        System.out.println(map.get("CRC"));
                        System.out.println(map.get("SIZE"));
                        System.out.println(map.get("PROGRESS"));
        }

        //System.out.println(myMap);

    }
