来个c版本

public class Flower_number {
    public static void main(String[] args) {
        int i=0;
        int m,n;
        for(int a=1;a<10;a++){
            for(int b=0;b<10;b++){
                for(int c=0;c<10;c++){
                    m=a*100+b*10+c;
                    n=a*a*a+b*b*b+c*c*c;
                    if(m==n){
                        i++;
                        System.out.println("水仙花数为"+m);
                    }
                }
            }
        }
        System.out.println("水仙花数总共有 "+i+" 个");
   
    }
}
打印结果：
    水仙花数为153
    水仙花数为370
    水仙花数为371
    水仙花数为407
    水仙花数总共有 4 个
   
谁能教我怎么显示
    水仙花数总共有 4 个
    水仙花数为153、370、371、407

            k=(p-j*10-i)/100;
            if(Math.pow(i,3)+Math.pow(j,3)+Math.pow(k, 3)==p)
                System.out.println(p);

这是我写的,就是感觉嵌套太多了

public class shuixianhua {
    public static void main(String [] args){
       Flower f=new  Flower();
       f.shuixianhua();
    }

}
   class Flower{
       int i;
       int j;
       int k;
       public void shuixianhua(){
           for(i=1;i<10;i++)
               for(j=1;j<10;j++)
                   for(k=1;k<10;k++)
                       if((i*i*i+j*j*j+k*k*k)==i*100+j*10+k*1)
                           System.out.println("水仙花数为："+i*100+j*10+k*1);
       }
   }
