Question

Java编程题，求解

编写程序,计算并输出n的阶乘的结果(n>=100)。注意,100阶乘超出了整数的最大取值范围

Answer 1

public class Yttt {

public static void main(String[] args) {
int n = 60;
int mult;
try{
mult = mult(n - 1, n);
}catch (Exception e){
mult = Integer.MAX_VALUE;
}
System.out.println(mult);
}

public static int mult(int n,int m){
if(n==0){
return 1;
}
int mult = mult(n - 1, n);
if(mult<0){
throw new RuntimeException("");
}
return mult*m;
}
}
