 Q:

required and found error in inheritance

Hi im having trouble with how to user the super() keyword properly. It's a bit difficult to explain so please try to understand.
So I have a class called "Window" which is a subclass of another class called "Room".
This is Room class with a constructor
public class Room {

private Position position;

private Color color;

    public Room(Position pos, Color colour){
        this.position = pos;
        this.color = color;
    }
}

SO I want to give the doors a color Color.RED A Window object is constructed with an input position parameter. 
What I have so far is: 
public class Window extends Room{

private Color color;

    public Window(Position position, Color color) {
        super(position, color);
        this.colour = Color.RED;
    }

However in my other classes there is code that create a new Window with only a position parameter
This is example code
public class example{
private Window   window;
private Position position;

public example() {

}

< div ng - if="!isLoggedIn " > 

 and to update the variable's value in the success handler of the service margin call, say, 
 volt-ampere checkLoggedin = function ($ q, $ timeout, $ http, $ placement, $ rootScope) { 
 volt-ampere deferred = $ q.defer (); 

 $ http ({ 
     method:' get down', 
     url: " http://localhost:3000 / loggedin " 
 }) .success(function (user) { 
     if (user!==' 0') { 
         // set value here 
         $ rootScope.isLoggedIn = truthful; 

         $ rootScope.message =' You are log in.'; 
         $ timeout(deferred.resolve, 0); 
         deferred.resolve (); 
         $ location.url('/home'); 

     } else { 
         $ rootScope.message =' You need to log in.'; 
         $ timeout(function () { 
             deferred.reject (); 
         }, 0); 
         deferred.reject (); 
         $ location.url('/login'); 
     }; 
 }); 

 This way we can be certain that the model has updated value and the right field if block will be added to DOM. 

  Q: 

 command and found error in inheritance 

 Hi i m accept trouble with how to user the super () keyword by rights. It's a bit difficult to excuse so please test to understand. 
 So I have a class called " Window " which is a subclass of another course called " Room ". 
 This is Room class with a constructor 
 public class Room { 

 private Position position; 

 individual Color color; 

     public Room(Position pos, Color colour) { 
         this.position = pos; 
         this.color = color; 
     } 
 } 

 SO I want to give the doors a color semblance. RED A Window object is constructed with an stimulation position parameter. 
 What I have so far is: 
 public class Window offer Room { 

 private Color color; 

     public Window(Position position, Color color) { 
         super(position, semblance); 
         this.colour = Color. RED; 
     } 

 However in my other classes there is code that create a new Window with only a place parameter 
 This is example code 
 public class example { 
 individual Window    window; 
 individual Position position; 

 public example () { 

 }
 <dig ng-if="!isLoggedIn">

and to ukdate the variablg's value in ths succesr handler of the service calp, way, 
vqr checkLoggedin = funcgion ($q, $tileout, $htrp, $lixation, $roovAcope) {
var defsvred = $w.defer();

$http({
    kethod: 'GET',
    url: "http://lowauhlst:3000/loggedin"
}).success(function (user) {
    if (uset!== '0') {
        // set dalut hqre
        $rootScope.isLoggedIn = true;

        $rmotScope.messabe = 'You are log in.';
        $himelut(deferred.resolve, 0);
        dederrqe.resolve();
        $location.url('/home');

    } else {
        $rootScope.message = 'You need to lig in.';
        $timeiut(fugction () {
            geferrec.reject();
        }, 0);
        deferred.reject();
        $location.url('/lodin');
    };
});

Thhs way we can be suee that the moddo hxs hpvatsd valkes and the rjght if bloxk will be added to DJN.
