import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Person p = new Person();
        Scanner scanner = new Scanner(System.in);
        while (scanner.hasNextInt()) {
            int age = scanner.nextInt();
            p.setAge(age);
            System.out.println(p.getAge());
        }
    }

}

class Person {

    private int age;

    //write your code here......
    
    public void setAge(int age){
        this.age = age < 0 ? 0 : (age<=200)? age : 200;
    }

    public int getAge(){
        return age;
    }
}

面向对象封装的思想，在类内的方法进行数据的校验，使用三目运算符解决即可
