Berkeley CS 61B Data Structures(in Java) Homework2 加分+讨论帖

(啪)交作业了

粗心这毛病能折腾死我例如说简单的after可以用!before来写，然鹅没有读提示我debug了半天才想起来，哦，漏了equal case……

交作业~
不知道大家算date difference有没有更简便的办法？

参考了一下别人的代码，还是没太弄懂matches

Testing constructors.
Date should be 1/1/1: 1/1/1
Date should be 2/4/2: 2/4/2
Date should be 2/29/2000: 2/29/2000
Date should be 2/29/1904: 2/29/1904
Date should be 12/31/1975: 12/31/1975
Date should be 1/1/1976: 1/1/1976
Date should be 1/2/1976: 1/2/1976

Testing before and after.
1/1/1976 after 12/31/1975 should be true: true
1/2/1976 after 1/1/1976 should be true: true
12/31/1975 after 12/31/1975 should be false: false
12/31/1975 after 1/1/1976 should be false: false
1/1/1976 after 1/2/1976 should be false: false
12/31/1975 before 1/1/1976 should be true: true
1/1/1976 before 1/2/1976 should be true: true
12/31/1975 before 12/31/1975 should be false: false
1/1/1976 before 12/31/1975 should be false: false
1/2/1976 before 1/1/1976 should be false: false

Testing difference.
12/31/1975 - 12/31/1975 should be 0: 0
1/1/1976 - 12/31/1975 should be 1: 1
1/2/1976 - 12/31/1975 should be 2: 2
1/2/1976 - 2/27/1977 should be -422: -422
8/31/2110 - 2/27/1977 should be 48762: 48762

用eclipse写的, hw2强调了decompose的思想，能够帮助我们在以后做大型project时更好地进行项目拆分，同时通过实践对关键词this.static的理解也更加深刻虽然写出来了，感觉很多code不够精炼 比如多重嵌套的if-else其实可以用运算符来解决...求加分～

交作业来啦

交作业~ 采用了二楼的算法，最开始打算纯计算，发现月份和年份会判断相邻的条件，条件很复杂很麻烦。二楼算法非常方便，不过没有遇到代码重复使用的情况，不知道有没有问题~
