*I just need "Flowchart" and "Pseudo code" for this problem*:

9. Circle Class Write a Circle class that has the following fields: * radius. a double PI. a final double initialized with the value 3.14159 The class should have the following methods: Constructor. Accepts the radius of the circle as an argument setRadius. A mutator method for the radius field. getRadius. An accessor method for the radius field. getArea. Returns the area of the circle, which is calculated as area = PI * radius * radius getDiameter. Returns the diameter of the circle, which is calculated as diameter = radius , 2 getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * PI * radius Write a program that demonstrates the Circle class by asking the user for the circles radius, creating a Circle object, then reports the circle's area, diameter, aci ircumference
