Question 27 / 297: Will the following code compile correctly?

abstract class AirPlane {

	abstract void fly();

	void land() { // line 5
		System.out.print("Landing..");
	}

}

class AirJet extends AirPlane {

	AirJet() {
		super(); // line 14
	}

	void fly() {
		System.out.print("Flying..");
	}
}

A Yes, it will compile with no errors

B No, because at line 5 method land() must be abstract since class AirPlane is abstract

C No, because class AirJet must override method land()

D No, because at line 14 AirJet constructor is calling the super() while AirPlane has no constructor
defined
