class - Needing help understanding piece of Java code -


i started learn java today, following head first java, 2nd edition, , have code, confusing me. i've got experience in python, new. more specific, don't understand boolean canrecord = false; do.

class dvdplayer {      boolean canrecord = false;      void recorddvd() {         system.out.println("dvd recording");     }     void playdvd() {        system.out.println("dvd playing");    }     }   class dvdplayertestdrive {     public static void main(string [] args) {          dvdplayer d = new dvdplayer();         d.canrecord = true;         d.playdvd();          if (d.canrecord == true) {             d.recorddvd();         }     } }

on class dvdplayer chose regular dvdplayer cannot record. set false.

if want record either change variable directly, did on class dvdplayertestdrive.

the boolean canrecord = false meant show possible reproduce behaviour of objects. in case have class should represent dvdplayer , know majority of dvdplayers not record.

don't focus on code during first approach object oriented programming (i assume first oop language too).

try understand concepts , ideas behind =)

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...
