以前看java书,都将IO作为一个大的章节甚至模块来编写,可见IO在java语言中的重要性. java的流按功能和处理的目标数据不同可以分为字节流和字符流.字符流处理的基本数据单元是字符:字节流处理的基本数据单元是字节.类关系结构图如下: 图片转自:https://blog.csdn.net/weixin_44411569/article/details/88788085 IO本身就是输入输出的意思,从上图可以看出,无论字符还是字节流,都是分为输入和输出两大块. 并且不管是输入还是输出流.字符流…

首先介绍下这3个文件的关系:可以说INPUT1.C的函数粒度最大,它的函数getdata()就完成了整个INPUT文件数据的读入,该函数又调用了INPUT2.C中的部分函数,INPUT2.C文件中的函数分为两类,一类是解析INPUT文件的函数:另一类是工具函数,包括将节点.管段数据存入哈希表中,构建哈希索引.字符串的匹配,从哈希表中查找数据等,该文件的粒度中等.而INPUT3.C的粒度是最细的,他是用于解析单行INPUT文件的对象内容并保存到内存中.INPUT3.C的组织结构也很简单,各个函数具…
