编写程序，实现以下功能：求m!+(m+1)!+...+(n-1)!+n!。m和n的值从键盘输入，且m<n。Java

以下是Java实现求m!+(m+1)!+...+(n-1)!+n!的程序：

import java.util.Scanner;

public class FactorialSum {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入m的值：");
        int m = scanner.nextInt();
        System.out.print("请输入n的值：");
        int n = scanner.nextInt();
        
        int sum = 0;
        int factorial = 1;
        
        for (int i = m; i <= n; i++) {
            factorial *= i;
            sum += factorial;
        }
        
        System.out.println("结果为：" + sum);
    }
}
