参考链接: Java InputStreamReader类 主要通过BufferedReader的readLine()方法按行读取字符串,如下代码所以 读取完毕后记得关闭文件流,最好统一放在finally中关闭 public void readLine(String path) { InputStreamReader isr = null; BufferedReader br = null; try { isr = new InputStreamReader(new FileInputStrea...

因此,建议用 BufferedReader 包装所有其 read() 操作可能开销很高的 Reader(如 FileReader 和 InputStreamReader)。例如: BufferedReader in =newBufferedReader(newFileReader("foo.in"))//将缓冲指定文件的输入。 返回目录 3.InputStreamReader InputStreamReader 是字节流通向字符流的桥梁:它使用指定的 charset 读取...
而BufferedReader则是让你高效“吃饭”的高级勺子。两者结合，就能让你在Java的世界里，优雅而高效地处理...
InputStreamReader reader = new InputStreamReader(in); // 这个构造方法只能传一个字符流。不能传字节流。 // reader是节点流。br是包装流。 BufferedReader br = new BufferedReader(reader);*///合并BufferedReader br =newBufferedReader(newInputStreamReader(newFileInputStream("Copy02.java"))); ...
BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); 3、规范用法 总结以上内容,得出比较好的规范用法: 1) File file = new File ("hello.txt"); FileInputStream in=new FileInputStream (file); 2) File file = new File ("hello.txt"); ...

而BufferedReader只是解析流数据并组成一行一行的String。"而InputStreamReader是Reader的一个子类 。 InputStreamReader中通过StreamDecoder这个辅助类来完成的。 "An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset"...
