Allowed to use language's json parser or have to manually create our own?

I guess it means that JSON parser (like JSON-P) should be used and there are 3 ways to implement that like object model (with common switch and tracking the value type or via tracking the type of object) or via streaming model.

public static void jsonToMap(String t) throws JSONException {

HashMap<String, String> map = new HashMap<String, String>();
JSONObject jObject = new JSONObject(t);
Iterator<?> keys = jObject.keys();

while( keys.hasNext() ){
String key = (String)keys.next();
String value = jObject.getString(key);
map.put(key, value);

}

System.out.println("json : "+jObject);
System.out.println("map : "+map);
}

Or if we don't want to use JSONObject library, we can write in the following way.

String tempJson = "{\"incomePhone\":\"213121122\",\"clientId\":\"1001\",\"clientAccountManager\":\"Gestor de Conta 1\",\"clientRetailBranch\":\"100\",\"phoneAccountManager\":\"7800100\"}";
System.out.println(tempJson);

String[] parts = tempJson.split(",");
HashMap<String,String> jsonHash = new HashMap<String,String>();

for(int i=0;i<parts.length;i++){
parts[i] = parts[i].replace("\"", "");
parts[i] = parts[i].replace("{", "");
parts[i] = parts[i].replace("}", "");
String[] subparts = parts[i].split(":");
jsonHash.put(subparts[0],subparts[1]);
}
