In this example we will check if user sends to bot a photo, if it is, get Photo's file_id and send this photo by file_id to user.
```java
// If it is a photo
if (update.hasMessage() && update.getMessage().hasPhoto()) {
// Array with photos
List<PhotoSize> photos = update.getMessage().getPhoto();
// Get largest photo's file_id
String f_id = photos.stream()
.sorted(Comparator.comparing(PhotoSize::getFileSize).reversed())
.findFirst()
.orElse(null).getFileId();
// Send photo by file_id we got before
SendPhoto msg = new SendPhoto()
.setChatId(update.getMessage().getChatId())
.setPhoto(f_id)
.setCaption("Photo");
try {
sendPhoto(msg); // Call method to send the photo
} catch (TelegramApiException e) {
e.printStackTrace();
}
}
