InputStream && OutputStream

InputStream OutputStream IntroductionAn important set of interfaces (actually abstract classes) in IO flow operations is InputStream and OutputStream.InputStream字节输入流其最核心的一个方法是read()方法OutputStream字节输出流其最核心的一个方法是write()方法所有字节输入输都要实现read方法,所有字节输出流都要实现write()方法。字节流可以操作任意类型的文件(二进制或文本文件)Start by understanding several concepts:01机器码:只有机器才能识别0101串字节:拿英文来说明就是英文字符所对应的ASCII码(a==>97)字符:就是我们人类能识别的字符文字备注:每种语言有自己对应的字节码比如英文一个字符只占一个字节(ASCII编码),但是中文可能就会占两个字节(gbk/gb2312)或三个字节(utf-8)取决于使用何种编码格式。InputStream Abstra

: 6c00 0000 h -- 6fff ffffh Note:Here, haddr is the internal AHB address line that needs to be converted to an external device. Each address corresponds to one byte unit. Therefore, if the address width of an external device is 8 bits, haddr [25:0] corresponds to the CPU pin fsmc_a [25:0] of stm32 one-to-one, and the maximum access space is 64 MB. If the address width of the external device is 16 bits, haddr [25] exactly corresponds to the CPU pin fsmc_a [24:0] of stm32. During application, yo

Let's take a look at the situation when * left_walk = old is executed below, * left_walk = old is equivalent to * (old-> next) = old, that is, old-> nex = old, however, the old value may not necessarily be the node pointed to by old-> next. It should be that left_walk and right_walk both point to their old nodes, but they are different. The algor
