Description
Parent class has protected int x as instance variable.
Parent's data method returns x value.
Parent's compute method returns x multiplied by the given dx
value.
A child class is a child of the parent class.
Child class has protected int y as instance variable other than
inherited.
The data method of the child class returns x + y.
Child class compute method receives dx and dy as arguments and
returns x * dx + y * dy.
Complete class Parent and class Child so that the given output
is produced.
[CONDITIONS]
1) Do what is necessary for overloading and overriding, but do
not do what is not necessary.
2) In toString of Child, toString of Parent must be used.
3) [Important] equals exists only in Parent, and cannot be
overridden or overloaded again in Child.
4) [Important] Equals must receive object type argument.
5) The main class of the code template cannot be changed at
all.
