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++; |
} |
|
} |
} |
