Computer Science (Java programming practice question)

Please help to answer thank you 

Complete the following tasks: (i) Create a CompareCircle interface, with a single method compare (Circle circle)that returns an integer value. Create an abstract class named Figure. The class has a double field radius to store the radius of a figure. Include a constructor that takes the field. The class has an abstract computeArea () method that should of the (ii) figure computeCircumference () method that should return the return the area and an instance circumference of the circle. (iii) Create a subclass of Figure named Circle. Implement the compare (Circle circle) method such that the method returns one (1) if the area of current circle is larger than the area of the input circle, zero (0) if the two areas are the same, and negative one (-1) if current circle is smaller than the input circle.
