public static void main(String[] args) throws InterruptedException{        List list = new ArrayList();        for (int i = 100; 1<2;i++ ){            int h = i/100;            int t = (i-100*h)/10;            int a = (i-10*t-100*h);            if (Math.pow(a,3)+Math.pow(t,3)+Math.pow(h,3)==i){                list.add(i);                System.out.println(list);            }//            Thread.sleep(1000);        }    }这样是有问题的，只能读到1001，因为会有千位出现，完善后：public static void main(String[] args) throws InterruptedException{    List list = new ArrayList();    for (int i = 100; i<100000;i++ ){        String tt = i+"";        int a =Integer.parseInt(tt.substring(tt.length()-3,tt.length()-2));        int t =Integer.parseInt(tt.substring(tt.length()-2,tt.length()-1));        int h =Integer.parseInt(tt.substring(tt.length()-1,tt.length()));        if (Math.pow(a,3)+Math.pow(t,3)+Math.pow(h,3)==i){            list.add(i);            System.out.println(list);        }    }}
