ORID_52

从上个月开始了CS61B（伯克利大学的一门计算机课程），这次是我上课的笔记和自己犯错的地方
Argument等于参数，constructor主要是为了能让这个class跑起来，英文就是initialize the class.

做好一个function之后无法return

这里还是出现了之前的问题，就是无法把自己的结果给出来。
参考MaxArray这里的想法，哦哦哦！！！
我居然把windowPosSum 设置成了integer，这能不在反馈的时候出问题吗？？

Notes

1. Functions must be declared as part of a class in java.
   A function that is part of a class is called a "method".

2. To define a function in Java we use "public static".

class is like a file in java, it is used to get a results or called upon a function.

member of a class are accessed using dot notation. For example, d.makenoise is calling "makenoise" method in "d" class
