原来static就是不用建立新的object，直接调用就可以了。
Head first java p275
The difference between regular(non-static) and static methods
Java is object-oriented, but once in a while you have a special case, typically a utility method (like the Math methods), where there is no need to have an instance of the class. The keyword static lets a method run without any instance of the class. A static method means "behavior not dependent on an instance variable, so no instance/object is required. just the class."

新增计划

定了新的计划，那就是争取5月之前把udemy的project做完，然后通过leetcode来丰富自己的面试经验，然后争取能拿到暑假的coop，这样开学重新回到学校不仅有经验，还不愁新学期的生活费和学费了。
