Try this:

Map<String, String> map = new HashMap<>();        
map.put("name", "sandeep");
map.put("age", "26");

List<String> list = new ArrayList<>();

for (Map.Entry<String, String> entry : map.entrySet()) {
    String field = entry.getKey();
    String value = entry.getValue();            
    list.add("\"" + field + "=" + value + "\"");
