class Vehicle {
int x;
Vehicle() {
this(10); // line n1
}
Vehicle(int x) {
this.x = x;
}
}
class Car extends Vehicle {
int y;
Car() {
super(); // line n2
this(20);
}
Car(int y) {
this.y = y;
}
public String toString() {
return super.x + ":" + this.y;
}
}
And given the code fragment:
Vehicle v = new Car();
System.out.println(v);
What is the result?
