Answer the following and code in Java

Thank you

Pre-Condition: Reuse the code of Point and Circle classes from the previous exercises. Update
the toString() of Circle to display the String representation of the object as follows:
Center Point: (1,2)
Radius: 1.5
a. Implement a class called Cylinder. A cylinder has a circle and one additional data member
for representing the height (type float).
b. Create appropriate constructors for your Cylinder class.
c. Encapsulate it.
d. Include methods for finding the volume and area of your Cylinder. Use float as return type
of each method.
area = 2 * (area of the circle in this cylinder) + (circumference of the circle in this cylinder) *
height
volume = (area of the circle in this cylinder) * height
e. Override the toString method of the Object class. Use the toString() of the Circle class then
concatenate the remaining values of the Cylinder object. Make sure the expected output in the
test cases are followed.
