Answer 1

public class Tester01 {
    public static void main(String[] args) throws Exception {
        int a = 8;
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("请输入一个数字");
        String input = br.readLine();
        int b = Integer.parseInt(input);
        if (b > a) {
            int sum = b / a;
            System.out.println(sum);
        } else {
            System.out.println("输入错误");
        }
    }
}

结果，是这样吗
