oop三次pta总结
前言
在这学期的java课程学习当中，我已经体会到了java这门语言的重要性了，就从这三次pta题目的计划与思路来说吧（还真的有点小难），特别是每一期pta的最后一题......
《答题判题步伐》，这道题目依次迭代，难度依次上升（如果没有计划好，基本是寄了），题目不多看几遍细节是真的不能把握，如果细节忽略了，那就要付出几倍的时间和
去修正了。(别问我怎么知道的)
这道题目涵盖正则表达式，类的计划，等知识点。从复杂到更复杂，时间泯灭的越来越多，（一个测试点一天）
接下来一题一题来分析看看吧，也总结一下本身的代码计划错误
计划与分析
题目1：
计划实现答题步伐，模仿一个小型的测试，要求输入题目信息和答题信息，根据输入题目信息中的标准答案判断答题的结果。
输入格式:
步伐输入信息分三部分：
1、题目数量
格式：整数数值，若超过1位最高位不能为0，
样例：34
2、题目内容
一行为一道题，可以输入多行数据。
格式："#N:"+题号+" "+"#Q:"+题目内容+" "#A:"+标准答案
格式约束：题目的输入顺序与题号不相干，不肯定按题号顺序从小到大输入。
样例：#N:1 #Q:1+1= #A:2
#N:2 #Q:2+2= #A:4
3、答题信息
答题信息按行输入，每一行为一组答案，每组答案包含第2部分所有题目的解题答案，答案的顺序号与题目题号相对应。
格式："#A:"+答案内容
格式约束：答案数量与第2部分题目的数量相同，答案之间以英文空格分隔。
样例：#A:2 #A:78- 2是题号为1的题目的答案
- 78是题号为2的题目的答案<br>
输特别式:
1、题目数量
格式：整数数值，若超过1位最高位不能为0，
样例：34
2、答题信息
一行为一道题的答题信息，根据题目的数量输出多行数据。
格式：题目内容+" ~"+答案
样例：1+1=~2
2+2= ~4
3、判题信息
判题信息为一行数据，一条答题记录每个答案的判断结果，答案的先后顺序与题目题号相对应。
格式：判题结果+" "+判题结果
格式约束：- 1、判题结果输出只能是true或者false，
- 2、判题信息的顺序与输入答题信息中的顺序相同<br>
