1122：亲密数（Java代码）@@

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;
           }
       }
 }
