A sub class has an 'is a' relationship with its superclass. This means that a sub class is a special kind of its super class. When we talk in terms of objects, a sub class object can also be treated as a super class object. And hence, we can assign the reference of a sub class object to a super class variable type. However, the reverse is not true. A reference of a super class object may not be assigned to a sub class variable. The following statements illustrate this concept by creating a Student object and assigning it to a Person variable. However, when we try to assign the reference of a Person object to a Student variable, we get a compilation error.
Innovators - Venturesome; innovators are the first to adopt a new product. They are willing to pay a high price to be the first to have something new.

Early majority - Value shoppers; the early majority do not adopt new products until they are sure the new product will have value for them.
Also, neither parent must be older than 45 years. In the case of adoption of older children, the age of the parents may be relaxed accordingly.

For a child who is less than a year old, the adoptive parents can have a maximum combined age of 90 years.
