Why am I receiving cannot refer to instance field when explicitly invoking a constructor after changing Dog constructor?

class Dog extends Animal { Dog() { super(sound: "bark"); //this line receives the error }

class Dog extends Animal { 
  Dog() { super(sound: "bark"); //this line receives the error 
}

// I removed sound:  
super(sound: "bark"); // to super("bark");

that worked for me no idea why.

Don't type "sound:" when you call the superclass. It's just a feature IntelliJ offers to show up the params which you're trying to set. It should look like this:

class Dog extends Animal { public Dog() {super("bark");} }
