cannot read string result from MYSQL

I want to have an if else statement inside a loop when getting the results of

data from mysql .. However the if statement cannot read the result.. but the codes are perfectly

I see the problem in my if else condition.

here is my Code from my asynctask

for (int i = 0; i < markers.length(); i++) {

                    JSONObject c = markers.getJSONObject(i);

                    // Storing each json item in variable
                    Double LAT = c.getDouble(TAG_LAT);
                    Double LNG = c.getDouble(TAG_LNG);
                    String color = c.getString(TAG_STATUS);

                   String red = "ongoing"; 
                    String green = "firedout"; 

                    if (color == red){
                    LatLng position = new LatLng(LAT, LNG);
                    status.add(new MarkerOptions()
                    .title(color)
                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED))
                    .position(position));
                    // adding HashList to ArrayList
                    }

                    if (color == green){
                        LatLng position = new LatLng(LAT, LNG);
                        status.add(new MarkerOptions()
                        .title(color)
                        .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN))
                        .position(position));
                        // adding HashList to ArrayList
                        }

                }
