abc=a的三次方+b的三次方+c的三次方,问这样的abc共有几个?

public class Test ...{
    public static void main(String[] args) ...{
        int i,j,k;
        for(i=1;i<=9;i++)...{
            for(j=0;j<=9;j++)...{
                for(k=0;k<=9;k++)...{
                    if(100*i+10*j+k==i*i*i+j*j*j+k*k*k)...{
                        System.out.println(i+"   "+j+"    "+k);
                    }
                    
                }
            }
        }

    }

}
