OO第三次博客作业

OO第三次博客作业

前言：

1、知识点总结：

① 字符串操作，正则表达式的训练及应用。

② 类与对象的设计，继承与多态，接口，内部类，抽象类

2、题量：不多

3、难度分析：

题目集8：难在7-1 电信计费系列1-座机计费：①理解题目的意思②理解类间关系③正则表达式

题目集9：难在7-1 电信计费系列2-手机+座机计费混合拨打

题目集10：相比前两个题目集较为简单

一、212016/71-题目集08——7-1 电信计费系列1-座机计费

　　1.题目（如下图）

 

 

 

　　2.源码设计与分析：

 

　本题肯定是要先理解清楚题目的意思，再去理解题目所给的类图，然后根据类图写好所需的类，之后在主类里写好方法

正则表达式：

String regex = "u-([0-9]){11,12} 0|t-[0-9]{11,12} [0-9]{10,12}( [0-9]{4}.([1-9]|10|11|12).([0-9]|[1-3][0-9]) ([0-9]|[0-2][0-9]):([0-5][0-9]):([0-5][0-9]))+|end";

二、212016/71-题目集09——7-1 电信计费系列2-手机+座机计费

 　　1.题目（如下图）

 

　　2.源码设计与分析：在上一个题目集的基础上添加手机用户，考虑接电话和市外，省外漫游的情况

　　正则表达式：

　　　　String regex = "u-([0-9]){10,12} (0|1)|u-1([0-9]){10} (1|3)|t-[0-9]{11,12}( [0-9]{3,4})? [0-9]{10,12}( [0-9]{3,4})?( [0-9]{4}.([1-9]|10|11|12).([0-9]|[1-3][0-9]) ([0-9]|[0-2][0-9]):([0-5][0-9]):([0-5][0-9])){2}|m-1[0-9]{10} 1[0-9]{10} ([0-9]|[a-zA-Z]|\\ |\\,|\\.)+|end";

总结:

 

学会了什么：

 

1.通过对本阶段综合性总结，我对Java的基础语法（选择、函数、字符字符串相关操作、循环、方法、数组）有了更深层次的理解

 

2.对类与对象的设计原则有了更深层次的理解，了解了继承原则和多态特性，抽象类和接口，并能在实际编程加以应用

 

3.了解了什么是接口、抽象类，并能熟练应用

 

还需要改进加强的地方：

 

1.考虑问题不够全面

 

2.主函数不能做到完全解耦

 

3.算法不够精确不够简单
