Variables:

The Dinosaur class must have these variables:

$$ name $$ the name of the dinosaur. This should be a String. It should be visible to subclasses of

Dinosaur. An invalid value should default to $$Dino$.$ The value is invalid if name is an empty

String, blank String, or null. This value cannot be changed once set and should be visible to any

descendant classes. Think about what modifiers fit best for this!

$$ height$$ a double representing the height of the dinosaur in feet.

$$ width$$ a double representing the width of the dinosaur in feet.

$$ weight$-$a double representing the weight in pounds.

$$ totalEnclosures $$ an int representing the total number of dinosaurs that have an

enclosure at the park. Think about what reserved word you need to use for this variable. It

should be visible to subclasses of Dinosaur.
