the factors of each perfect number to confirm that the number is indeed perfect. Challenge the computing power of your computer by testing numbers much larger than 1000. Display the results.*/ import java.util.Scanner; import java.util.Date; public class PerfectNumber { public static boolean is...
Write a Java program that categorizes integers between 1 and 10,000 as Abundant, Deficient, and Perfect.In number theory, an abundant number is a number for which the sum of its proper divisors is greater than the number itself. Example : The first few abundant numbers are: 12, 18, 20...

We consider a positive integer perfect, if and only if the sum of its digits is exactly 10. Given a positive integer k, your task is to find the k-th smallest perfect positive integer. Input A single line with a positive integer k (1≤k≤10000). Output A single number, denoting the...
In Java, checking whether a number is a perfect square or not is a common task. A number is called a perfect square if it can be expressed as the product of an integer with itself. For example, 16 is a perfect square because it is the result of multiplying 4 × 4. ...
定义Perfect Number是一个正整数,它等于除了它自己之外的所有正除数的总和。现在,给定一个整数n,编写一个函数,当它是一个完美数字时返回true,否则返回false。 解法:直接解就可以。注意处理num是1的时候。还有技巧是,只计算num/2就可以,如果能整除就把除数和结果都累加。
Write a Java program to find the next perfect square that is greater than a specified number. Write a Java program to count the number of perfect squares within a specified numerical range. Write a Java program to determine if a number is a perfect square without using built-in square root...
