java课堂作业（十二）

题目：自定义一个学生类和相应异常类，属性有：姓名、年龄。如果用户在给学生年龄赋值时，如果年龄小于0 则抛出一个AgeLT0Exception，如果年龄大于150 抛出一个AgeGT150Exception

package com.zhuoyue.ch12;

public class AgeLT0Exception extends Exception{

    /**
     * 
     */
    private static final long serialVersionUID = -3655506382017253195L;
    
    public AgeLT0Exception(){
        super();
    }
    
    public AgeLT0Exception(String message){
        super(message);
    }

}

package com.zhuoyue.ch12;

public class AgeGT150Exception extends Exception {

    /**
     * 
     */
    private static final long serialVersionUID = -2518423261295977881L;
    
    public AgeGT150Exception(){
        super();
    }
    
    public AgeGT150Exception(String message){
        super(message);
    }

}

package com.zhuoyue.ch12;

public class TestException {

    public static void main(String[] args) {
        //要么捕获异常，程序员处理。要么抛出异常，有上一级处理
        try {
            Student s1 = new Student("小明",-1);
        } catch (AgeLT0Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (AgeGT150Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        try {
            Student s2 = new Student("小红",156);
        } catch (AgeLT0Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (AgeGT150Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
