1. (论述题) 1、自定义异常类：年龄异常 输出错误提示：非正常学生年龄 2、学生类：姓名，性别，年龄 Setter年龄，检查小于15，大于80，抛出“年龄异常”给上级 3、测试类 录入学生信息，输入年龄 捕捉非数字异常，异常时显示信息：输入年龄不是数字 捕捉年龄异常，异常时显示信息：非正常学生年龄 如果正常，getter方法输出学生信息

自定义异常类：年龄异常

public class AgeException extends Exception {
    public AgeException() {
        super("非正常学生年龄");
    }
}

学生类：姓名，性别，年龄

public class Student {
    private String name;
    private String gender;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) throws AgeException {
        if (age < 15 || age > 80) {
            throw new AgeException();
        }
        this.age = age;
    }
}

测试类

import java.util.Scanner;

public class Test {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Student student = new Student();

        System.out.print("请输入学生姓名：");
        student.setName(scanner.nextLine());

        System.out.print("请输入学生性别：");
        student.setGender(scanner.nextLine());

        try {
            System.out.print("请输入学生年龄：");
            int age = Integer.parseInt(scanner.nextLine());
            student.setAge(age);

            System.out.println("学生信息：");
            System.out.println("姓名：" + student.getName());
            System.out.println("性别：" + student.getGender());
            System.out.println("年龄：" + student.getAge());
        } catch (NumberFormatException e) {
            System.out.println("输入年龄不是数字");
        } catch (AgeException e) {
            System.out.println(e.getMessage());
        }
    }
}
