java之IO节点流示例，其他情况举一反三都是类似的

- I/O流的一般操作流程： - 创建或者选择数据源 - 选择I/O流 - 创建操作对象 - 创建读取or存储的缓存区 - 具体操作，写入，读取，转换等等 - **出现乱码原因**：字节转字符，**字节数不够**，导致乱码；**编码不一致**导致乱码 - 注意事...

JAVA IO操作总结——节点流和处理流

JAVA IO操作总结——节点流和处理流按照流是否直接与特定的地方(如磁盘、内存、设备等)相连，分为节点流和处理流两类。节点流：可以从或向一个特定的地方（节点）读写数据。如FileReader 处理流：是对一个已存在的流的连接和封装，通过所封装的流的功能调用实现数据读写。如BufferedRea...
