public class Demo {
    public static void main(String[] args) {
        
            int count = 0;            //定义初始变量为0
        for (int i = 100;i <= 999;i++) {
               
            int ge = i % 10 ;         //个位的值
            int shi = (i / 10) % 100;     //十位的值
            int bai = i / 100 % 10;        //百位的值
            if (i == (ge*ge*ge + shi*shi*shi + bai*bai*bai))

{
                count++;
                System.out.println(i);   
            }
            
        }    System.out.println(count);
        
    }
}

........

十位的值求错了，shi = i / 10 % 10;或 shi = i % 100 /10;都行

楼上正解，建议大括号好好排版
