.asFormUrlEncoded（）从hashMap检索数据<String, String>

Question

I'm sending a video file along with some user details to my play framework application using MultipartRequest, the user details are added to a hashmap Map<String, String> myMap; on the server side I have retrieved my video file using . asMultipartFormData();

I was trying to retrieve my map using . asFormUrlEncoded(); but that uses Map<String, String[]>

So I've only been able to retrieve one value from my hash map, if I try to retrieve anymore using this code

for(int i =0; i < myMap.size(); i++){
            String param = "param" + (i + 1);
            System.out.println(myMap.get(param)[i]);    
        }

I get an arrayOutOfBounds error, is there an alternative solution to retrieve the data from the MultipartFormData, or can I implement my loop differently?

maybe I shouldn't be using .asFormUrlEncoded(); at all to retrieve the hashmap?

EDIT

I've modifed my code to use an iterator

Iterator<String> myVeryOwnIterator = myMap.keySet().iterator();
        while(myVeryOwnIterator.hasNext()) {
            String key=(String)myVeryOwnIterator.next();
            String[] value= myMap.get(key);
            System.out.println(key + " " + value);
        }

This prints my key, but returns Ljava.lang.String;@ for the values, I think this is because the .asFormUrlEncoded(); is expecting a <String, string[]> , but my hashMap uses <String, String> any solution to this?

Answer 1

This was the solution:

    Iterator<String> myVeryOwnIterator = myMap.keySet().iterator();
    while(myVeryOwnIterator.hasNext()) {
        String key=(String)myVeryOwnIterator.next();
        String[] value= myMap.get(key);
        System.out.println(key + " " + value[0]);
    }
