Suppose that you need a FullName class, which will contain a person's first name and last name.?

There are two different ways of implementing this.

A. The public variable version:

class FullName

{

public String first;

public String last;

}

B. The bean-style accessor version:

class FullName

{

private String first;

private String last;

public String getFirst() { return first; }

public void setFirst(String s) { first = s; }

public String getLast() { return last; }

public void setLast(String s) { last = s; }

}

Questions:

1. What are the benefits of using the public variable version?

2. What are the benefits of using the bean-style accessor version?

3. Add a constructor to your preferred version, that takes two String parameters and initializes first and last.
