BufferedInputStream(InputStream in) 创建一个有32字节的缓存区 BufferedInputStream(InputStream in, int size) 创建一个有size大小字节的缓存区 关键方法: read() read(byte[] buffer, int byteOffset, int byteCount) 常用使用方式: BufferedInputStream buf = new BufferedInputStream(new FileInputStream("file.jav...
where the unbuffered stream object is passed to the constructor for a buffered stream class. Here's how you might modify the constructor invocations in theCopyCharactersexample to use buffered I/O:
BufferedOutputStream BufferedOutputStream 是缓冲输出流。它继承于FilterOutputStream。 BufferedOutputStream 的作用是为另一个输出流提供“缓冲功能”。 BufferedOutputStream 函数列表: BufferedOutputStream(OutputStream out) BufferedOutputStream(OutputStream out, int size) synchronized void close() synchronized void ...
BufferedInputStream 和 BufferedOutputStream 都是在内部借助于字节数组,来实现缓存的 BufferedInputStream buf[]; 用于实际存储字节数组的值 DEFAULT_BUFFER_SIZE 表示默认缓冲区的大小 MAX_BUFFER_SIZE 表示 最大支持的缓冲区大小 这三个字段用于存储缓冲 pos 用于记录读取位置 ...

1、BufferedInputStream类可以对任何的InputStream类进行带缓存区的包装以达到性能的优化。 BufferedInputStream类的两种构造方法: (1)BufferedInputStream(InputStream in) //创建了一个带有32个字节的缓存流 (2)BufferedInputStream(InputStream in, int size) //创建一个按照指定的大小来创建缓存区 ...

JAVA分为字节流（Stream结尾）和字符流（Reader、Write结尾），再分为输入流（InputStream、Reader）和输出流（OutputStream、Write），输入输出相对于内存而言。在读字符的时候用字符流，如文本文件、XML等。在读二进制文件时候用字节流，如RAR、EXE等不是文本以外的文件。Buffered开头的流只是加了缓冲区，...
