Berkeley CS 61B Data Structures(in Java) Project1 加分+讨论帖

交作业啦

终于做完了..

图1为part1的结果，图2-3为part234的结果
总共完成时间应该是4天左右，
第一个不是很难，第二个读题非常难受，半天都不明白，实际上写的时候是默认了RGB三种颜色出现的前后相同时出现的频率是一样的，然后写起来就好一些。
第三个问题不大，只是在toPixel()进行检测的时候有些小问题检测不出来。
第四个确实很难，难度都在于debug，需要考虑的情况很多，在debug时会发现新的情况和之前写过的比如break;忘了加类似的错误。总的来讲几个method有以下需要考虑的问题

4.13 上午
boxBlur()：
numIterations每一此都需要一个新的PixImage，否则n次的结果也等于1次。
需要建立一个数组引用 引用的对象必须初始化，并且第一个要设为原PixImage，这样一共有n+1个引用，注意这一点。
toString()输出的顺序，外循环应该是Height，内循环是Width，不然看起来像做了转置一样，还以为是boxBlur出错，在boxBlur里面改等于南辕北辙。

Sobel()
这个有个自己的问题大家忽略，问题出在indiceY越界，函数中把indiceY = j - (currentHei-1)写成了indiceY = j - (currentWid-1)造成。

Blur()
需要两个jai，在文件夹里面，通过package里面的buildpath创建路径，这样消除了一直显示的error，方法来源于本帖子第四页的老哥，谢谢你。
然后注释了函数中大多数print，感觉没什么用，只有最后的blurFile和次数那个fireld留下来了。
在Blur主函数里面，本来使用的是args给启动Blur的blurFile方法传递参数，这里args不太会用我直接将其改为了文件名，这里有个小细节文件名一定要有.tiff的后缀。

Sobel()
主要问题与Blur相同。

SetPixel()
首先分为(x,y)在DListNode里靠前中间靠后三种情况，另外这里忽略了一点一定要考虑DListNode里面频率为1的情况，单独讨论又分为abc变acc，abc变aac，abc变adc；或者ab变bb，ab变ac；以及类似（这里a代表了只有一个频率的节点）。
当1减为0时，这种情况需要将原节点删除（其实更简单是方法是修改原节点）。
如果使用了RunIterator，在第一个节点删除的时候需要把RunIterator切换，因为RunIterator指向的head。
用toString()来debug很方便。
最后一个bug insert方法引用少指了一个出了问题。

写了很久，也是刚刚起步，有问题对解答和对题目都不明白的都欢迎大家交流。
代码不放了，实在有需要的可以参考 https://github.com/xuanyangece/CS61B.git 里面的pj1 branch。

最后希望加个学分感谢

请问Part II里的RunIterator本质上就是造一个Node的reference吗？另外PartIV的setPixe()需要访问DoublyLinkedList 的node，这样就要把Node这个类里的变量和方法都设为public吗？（是不是一般List里的Node都应该是private?）为什么不能直接用node去访问list呢，还要造一个RunIterator？

我的解答：

欢迎讨论！

用了一整天终于做完这个project了啊啊啊好累。主要是part 4 里要仔细分析各种情况，然后每种情况里都不能有小错误。
我会说我有个地方多加了1检查了一下午吗。。。
嗯，求加分
