Cannot escape double quotation in JAVA

I'm struggling to escape the double quotation marks when I try to convert my Map to String

//iterate through map and append to array
    StringBuilder mapAsString = new StringBuilder("{");
    for (String key : billingDetails.keySet()) {
        mapAsString.append(key + ":" + billingDetails.get(key) + ", ");
    }
    mapAsString.delete(mapAsString.length()-2, mapAsString.length()).append("}");
    String bdResult = mapAsString.toString();

Current output

"position": [
"{2018:Element3, 2012:Element2, 2010:Element1}"

Expected output

"position": [
"{"2018":"Element3", "2012":"Element2", "2010":"Element1"}"

Following method appends the contents of the Map to String however I can't seem to figure out how to escape the quotation marks so that the expected output is correct

 mapAsString.append(key + ":" + billingDetails.get(key) + ", ");

Escaping characters in java has always been somewhat of a difficulty for me and I would appreciate it if someone with a wider knowledge would help me out

Cheers and thanks

Escape the quotes with an backslash

mapAsString.append("\"" + key + "\":\"" + billingDetails.get(key) + "\", ");
