You can also use JSONObject class from json.org to this will convert your HashMap to JSON string which is well formatted

Example:

Map map = new HashMap<>();
map.put("myNumber", 100);
map.put("myString", "String");

JSONObject json= new JSONObject(map);

String result= json.toString();

System.out.print(result);

result:

{'myNumber':100, 'myString':'String'}

Your can also get key from it like

System.out.print(json.get("myNumber"));

result:

100
