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. Constructor. A no-arg constructor that sets the radius field to 0.0. 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 circle’s radius, creating a Circle object, and then reporting the circle’s area, diameter, and circumference. Temperature Class

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.
