要求：输出从1-1000之间的所有水仙花数

实现代码如下：

package Java_004水仙花数;

public class main{
	public static void main(String[] args){
		System.out.println("output:please num");
		int number = 100;
		int i, j, k;
		for (int sum; number<1000; number++){
			i=number/100; 
			j=(number-i*100)/10;
			k=number-i*100-j*10;
			sum=i*i*i+j*j*j+k*k*k;
			if (sum==number) 
				System.out.println(number+" is a dafodil number! ");
		}
	}
	
}
