public class Main {
    
    public static void main(String[] args) {
        
        for(int i = 10000 ; i <= 99999 ; i++) {
            int sum = 0 ;
            for(int j = 0 ; j < 5 ; j++) {
                int shang = i / (int)Math.pow(10,j);
                int yu = i % (int)Math.pow(10,j);
                sum += shang * yu;
            }
            if(sum == i) {
                System.out.print( i + " ");
            }
        }
    }
}

完全可以暴力求完结果之后，存一个数组数组，“自欺欺人”变快了

public class Main {
    
    public static void main(String[] args) {
        
        int[] arr = {14610, 16420, 23610, 34420, 65500};
        for(int i = 0 ; i < 5 ; i++) {
            System.out.print(arr[i] + " ");
        }
    }
}
