What will be the result of compiling and running the given code?
class A{intb=10;
private A(){this.b=7;
}int f(){
return b;
}
}class B extends A{intb;
}public class Test{public static void main(String[] args){
A a = new B();
System.out.println(a.f());
}
}
The code does not compile because the constructor of class A is declared as private. This creates a problem when the subclass constructor makes an implicit super() call to the parent class constructor at the time B is instantiated.
Since the code does not compile, all the other choices are incorrect. If the constructor of A had not been private, the output would have been 7.
