1、java.io.BufferedReader和java.io.BufferedWriter类各拥有8192字符的缓冲区。当BufferedReader在读取文本文件时,会先尽量从文件中读入字符数据并置入缓冲区,而之后若使用read()方法,会先从缓冲区中进行读取。如果缓冲区数据不足,才会再从文件中读取,使用BufferedWriter时,写入的数据并不会先输出到目的地,而是先存储至...
Java IO (3) - Reader 前言 JavaIO一共包括两种,一种是stream,一种是reader/writer,每种又包括in/out,所以一共是四种包。Java 流在处理上分为字符流和字节流。字符流处理的单元为 2 个字节的 Unicode 字符,分别操作字符、字符数组或字符串,而字节流处理单元为 1 个字节,操作字节和字节数组。
Java IO之Reader与Writer对象常用操作(包含了编码问题的处理) 涉及到文件(非文件夹)内容的操作,如果是纯文本的情况下,除了要用到File(见之前文章),另外就必须用到字符输入流或字符输出流。 字符输入流:该流处理时,数据由外部流向程序(内存),一般指代“读取字符”,更清晰点地说:从外部读取字符数据到内存中。
