You will write the code to implement a hierarchy of the classes human, student and worker. define a class human holding a first name and a last name. define a class student derived from the human that has a field student number (6 digits). define a class worker derived from human with fields weeksalary and workhoursperday and method getmoneyperhour() which returns the payment earned by hour by the worker. define the proper constructors and methods for the classes in your class hierarchy. initialize an array of 10 students and print their last name. initialize a list of 10 workers and sort them by payment per hour in descending order.

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !
