Write a program that reads in an integer greater than 1 in from the user. the program then computes and print out the factorial of the number read in. the factorial of a number is the product of all the natural numbers less than or equal to the number itself. that is the factorial of n is 1*2*3* (n-2)*(n1)*n. your program should stop if the user enters a negative number. design you will probably want to make a class called integer which has a single instance variable of class int. this class would also have an accessor method for the value and a method factorial, which will compute the factorial. this separates the input and output from the computation. sample output enter a number: 5 the factorial of 5 is 120. enter a number: 8 the factorial of 8 is 40320. enter a number: 12 the factorial of 12 is 479001600. enter a number: -1 you and bye.

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
