Or there are fewer people who understand this level.Yes, you have to open up some pages to introduce AWT and swing ...Forget to put this double-click execution of the small program to contrib

If a number equals its sum of all the factors that do not include itself, then this number is called the total number. For example, 6 of all factors that do not include itself are 6=1+2+3, and the 6 is a complete number.About more than 2,200 years ago, Euclid proposed: If 2n-1 is prime, then 2n-1 (2n-1) is a complete number. Would you please write down the next complete number after 6, based on this conclusion? public class Test {public static void main (string[] args) { //TODO auto-ge
