本文整理了Java中java.io.BufferedReader.read()方法的一些代码示例，展示了BufferedReader.read()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。BufferedReader.read()方法的具体详情如下：
包路径：java.io.BufferedReader
类名称：BufferedReader
方法名：read

BufferedReader.read介绍

[英]Reads a single character from this reader and returns it with the two higher-order bytes set to 0. If possible, BufferedReader returns a character from the buffer. If there are no characters available in the buffer, it fills the buffer and then returns a character. It returns -1 if there are no more characters in the source reader.
[中]从该读取器读取单个字符，并返回它，其中两个高阶字节设置为0。如果可能，BufferedReader将从缓冲区返回一个字符。如果缓冲区中没有可用字符，它将填充缓冲区，然后返回一个字符。如果源读取器中没有更多字符，则返回-1。

代码示例

BufferedReader br = new BufferedReader(new InputStreamReader(System.in, Charset.forName("ISO-8859-1")),1024);
 // ...
    // inside some iteration / processing logic:
    if (br.ready()) {
      int readCount = br.read(inputData, bufferOffset, inputData.length-bufferOffset);
    }
