C语言训练-亲密数 （Java代码）

解题思路:





注意事项:





参考代码:

public class Main {

public static void main(String[] args) {

int sum1 = 0;

int B = 0;

for (int A = 1; A <= 3000; A++) {

for (int i = 1; i < A; i++) {

if (A % i == 0)

B += i;//把A的因数赋值给B

}

for (int i = 1; i < B; i++) {//把B的因数赋值给sum1

if (B % i == 0)

sum1 += i;

}

if (sum1 == A & A != B & A < B) {//如果sum1等于A则输出

System.out.print("(" + A + "," + B + ")");

}

sum1 = 0;

B = 0;

}

}

}
