''Parent p = new Child()''
..... Pretty much the same thing.
Declaration of a variable named p and type Parent.
On the same line this variable is initialized. The value it's initiliazed with is an instance of class Child, by calling the constructor new Child()
It has the implicit requirement that class Child is a subtype of type Parent (probably a class too, so Child is a descendant class of Parent, probably a direct subclass that extends Parent.)
The names strongly suggested that requirement.
