Mass and weight
scientists measure an object’s mass in kilograms and its weight in newtons. if you know the amount of mass that an object has, you can calculate its weight, in newtons, with the following formula:

weight = mass x 9.8

write a program that asks the user to enter an object’s mass, and then calculate its weight. if the object weighs more than 1000 newtons, display a message indicating that it is too heavy. if the object weighs less than 10 newtons, display a message indicating that the object is too light.

note: you must use the joptionpane class to read input (input dialog box) and display output (message dialog box). also, remember that the public class and the filename of the source code file must match.
