(This exercise should be used in combination with Exercises 2 and 3.) Write a definition for a

Point

class. Provide two

double

instance variables,

x

and

y.

Provide a two-parameter constructor that initializes

x

and

y.

Provide a

shiftRight

method that shifts the point in the

x

direction by the value of the method’s

double

parameter,

shiftAmount.

Provide a

shiftUp

method that shifts the point in the y direction by the value of the method’s

double

parameter,

shiftAmount.

Make each of these methods return values that enable chaining. Provide accessor methods to retrieve the values of the two instance variables.
