关于java:Java中的IO流

Java 中的 IO 流分类

  • 输出 IO 流

    • 输出字节流(InputStream

      • 解决流

        • 缓冲流(BufferedInputStream
        • 转换流
        • 数据流(DataInputStream
      • 规范流(System.inInputStream))
    • 输出字符流(Reader

      • 解决流

        • 缓冲流(BufferedReader
        • 转换流(InputStreamReader
        • 数据流
      • 规范流

UML 关系图如下所示

PantUML 语法
A <|-- B // B 继承 A
C <|... D // D 实现了 C 
@startuml

abstract class InputStream{
}

class BufferedInputStream{
}

class FilterInputStream{
}

class DataInputStream{
}

interface DataInput{
}

abstract class Reader{
}

class BufferedReader{
}

class InputStreamReader{
}

FilterInputStream <|-- BufferedInputStream
InputStream <|-- FilterInputStream

FilterInputStream <|-- DataInputStream
DataInput <|.. DataInputStream

Reader <|-- BufferedReader

Reader <|-- InputStreamReader

  • 输入 IO 流

    • 输入字节流(OutputStream

      • 解决流

        • 缓冲流(BufferedOutputStream
        • 转换流
        • 数据流(DataOutputStream
      • 规范流(System.outPrintStream))
    • 输入字符流(Writer

      • 解决流

        • 缓冲流(BufferedWriter
        • 转换流(OutputStreamWriter
        • 数据流
      • 规范流(PrintWriter
