Question 3:

In this question, you must write part of a "main" method to solve a problem using two classes that you can assume are provided already.

Here are the classes that are provided. The contents of the methods are omitted, because you don't need to know how they work.

class Person {

public int howManyChildren() { ... }

// returns an integer that is the number of children the Person has

public String getName() { ... }

// returns the name of the Person

}

class PersonReader {

public PersonReader() { ... }

// a constructor - creates its own Reader object, and whatever else it needs

public Person readPerson() { ... }

// reads enough input data to make an object of the class Person, and returns that object. (This is like

// Formats readLine( ) method, which reads and returns a String.

}

Complete the program below. It is intended to read the data about 20 people, storing each in an object of type Person. Then it prints the name of the Person(s) with the largest number of children. Your code should handle case where two or more parents have the same number of children (that could be highest).

public class WhoHasTheMostChildren {

public static void main (String[] args) {

.....

}

}

Question 4;

1)Write an example to demonstrate overriding of static methods?

2)How is dynamic binding useful in enabling a small executable size in Java? Explain.
