使用throw抛出年龄异常

实现代码:

/**
 * @author Administrator
 *    用户信息
 */
public class User {
    private String name;
    private int age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    //setAge设置输入年龄,并判断是否符合条件,不符合就使用throw抛出异常
    public void setAge(int age) throws Exception {
        if(age > 0 && age <= 100) {
            this.age = age;
        }else {
            //抛出异常信息
            throw new Exception("年龄必须在1到100之间!");
        }
        
    }
    
}

import java.util.Scanner;

public class UsreDome {
    static Scanner input = new Scanner(System.in); 
    public static void main(String[] args) {
        User user = new User();
        System.out.println("请输入姓名:");
        user.setName(input.next());
        System.out.println("请输入年龄:");
        //捕获setAge抛出的异常信息并处理
        try {
            user.setAge(input.nextInt());
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}


 

运行结果:
