5!(简单的了解for循环与递归的区别)

public class Five_factorial {public static void main(String[] args) {/*** 1.普通方法实现5的阶乘*/int f = 1;for (int i = 5; i >= 1; i--) {f *= i;}System.out.println(f);/*** 2.运用递归实现5的阶乘*/int n = 5;Five_factorial five_factorial = new Five_factorial();factorial fa = five_factorial.new factorial();System.out.println(fa.fact(n));}class factorial {int fact(int n) {int value = 0;if (n == 1) {value = 1;} else {value = n * fact(n - 1);}return value;}}}
