打印出100—999之间的所有"水仙花数",所谓的"水仙花数"，
是指一个3位数其各位数字立方和等于该数本身。
例如:153=1^3+5^3+3^3------>153=1+125+27

我的思路是:   (错的。请大家帮忙)
package exercises;

public class Shuixian {
    public static void main(String[] args) {
        for (int i = 100; i <= 999; i++) {
            int x = i / 100;
            int y = x / 10;
            int z = i % 10;
            int no = 100 * x + 10 * y + z;
            int Shui = x * x * x + y * y * y + z * z * z;
            if (Shui == no) {
                System.out.println(no);
            }

        }

    }

}

该成这样就可以了public class Test1 {
 
    public static void main(String[] args) {
         int x,y,z;
         for(int i=1;i<999;i++){
            
             x=i/100;
             y=(i/10)%10;
             z=(i+10)%10;
             int all=x*x*x+y*y*y+z*z*z;
             if(all==i){
                 System.out.println(i);
             }
            
         }

    }

}

        int a, b, c;
        for (int i = 100; i < 999; i++) {
            a = i / 100;
            b = i / 10 - a * 10;
            c = i % 10;
            if (a * a * a + b * b * b + c * c * c == i) {
                System.out.println(i);
            }
        }

不错，不错。  哈哈。
   搞定
     感谢
