Asuperb number is an integer which is less than the sum of its proper divisors, excluding itself. thus, 12 is a superb number because 1, 2, 3, and 6 are its proper positive divisors and 1 + 2 + 3 + 4 + 6 > 12. the next superb number is 18 < 1 + 2 + 3 + 6 + 9. the next two superb numbers are 20 and 24. write a function called superb that returns true if the argument passed to it is a superb number and false otherwise.

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.
