字节流PK字符流

字节流： 顶层抽象类;InputStream OutputStream 常用子类： FileInputStream:从文件读入的输入流 FileOutputStream:从文件写入的输出流

字符流： InputStreamReader:字节流转换为字符流 //读取e盘下panda.txt的文件中字符 InputStreamReader reader = new InputStreamReader(new FileInputStream(“E:/panda.txt”));

OutputStreamWriter:字节流转换为字符流 OutputStreamWriter writer = new OutputStreamWriter(new FileOutputStream(“E:/panda.txt”)); String str = “hello panda”; writer.write(str); writer.flush(); writer.close();
