Convert HashMap.toString() back to HashMap in Java

Question

I put a key-value pair in a Java HashMap and converted it to a String using the toString() method.

Is it possible to convert t

Answer 1

Are you restricted to use only HashMap ??

Why can't it be so much flexible JSONObject you can do a lot with it.

You can convert String jsonString to JSONObject jsonObj

JSONObject jsonObj = new JSONObject(jsonString);
Iterator it = jsonObj.keys();

while(it.hasNext())
{
    String key = it.next().toString();
    String value = jsonObj.get(key).toString();
}
