Consider the following class:
public class FrozenDesert{
public FrozenDesert()
{
System. out. println("Yum");
}
}
You write a class, FrozenYogurt, which extends FrozenDesert. Which of the following is a correct implementation of the constructor for FrozenYogurt?
I. public FrozenYogurt() { System. out. println("I'm the new ice cream"); super(); }
II. public FrozenYogurt() { super(); System. out. println("I'm the new ice cream"); super(); }
III. public FrozenYogurt() { super(); System. out. println("I'm the new ice cream"); }

a. I only
b. II only
c. III only
d. I and II
e. I, II and III

Option c is the correct answer for the above question.

Explanation:

The super is a keyword in java which is used to call the parent class constructor from the child class constructor, but the only one thing is important to write the super is the constructor that the super keyword needs to be written as a first-line where it is used.The above question has three option which holds the constructor, in which option 1 and 2 holds the super keyword as the last line. So this option is not to hold the correct constructor.But option 3 will hold the Super as the first line, Hence this is the correct use of the constructor.And Only option c states about option 3 while the other is states about the other option. Hence option c is the correct answer.
