编写程序打印出所有的水仙花数，水仙花数是一个三位数，其各位数字立方和等于该数

[java]代码库

方法1：
public class Main {

	public static void main(String[] args) {
		int [] a = new int[1000];
		int j = 0;
		for(int i = 100; i < 1000; i++)
		{
			int num1 = i / 100;
			int num2 = i%100/10;
			int num3 = i%100%10;
			int numall = num1*num1*num1 + num2*num2*num2 + num3*num3*num3;
			if(i == numall)
			{
				a[j] = i;
				j++;
			}
				
		}
		for(int k = 0; k < j; k++)
		{
			if(k == 0)
				System.out.print(a[k]);
			else
				System.out.print("," + a[k]);
		}
	}

}

方法2：
import java.util.*; 
public class Main{
	
	public static void main(String[] args) {
		int i, j = 0, a, b, c;
		for(i = 100; i < 1000; i++) {
			int data = i;
			a = data%10;
			data = data/10;
			b = data%10;
			data = data/10;
			c = data;
			if(i == a*a*a+b*b*b+c*c*c) {
				if(j == 0)
				   System.out.print(i);
				else
					System.out.print("," +i);
				j++;
			}
			
		}
	}
}
