Not what you're looking for?
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?
