Berkeley CS 61B Data Structures(in Java) Lab2 讨论帖

调用方法不同 frac产生的数也不同 一开始死活搞不出0/1 后来发现时toString（） 和 gcd的问题  就加了俩个if

lab2 finished!

总结一下学到的知识：
1.Reuse code whenever possible to i)make the programme shorter  ii)make it easier for locating and fixing bugs.
2.The use of the keyword "this" in a constructor to invoke other constructors.
3.Convert other data types to string by simply concatenating the object with a string object.
4.The recursive algorithm for finding the greatest common divisor.

想了很久那个numberOfFractions的问题，抱着试下的心理加了static，得了。加深了对Static的理解。感恩！

学到的知识点:
1) use this to reuse the code, have reduced duplicate code
2) the knowledge of static key word
3) the greatest common divisor (GCD) of two positive integers
4) override toString() method

嗯，还得加深对static的理解！

Lab2, Fraction:

期末考完了，继续跟课

打卡交作业~
