如下所示：
public static void main(String[] args) throws IOException {
/*
* 1.打开一个file
* 2.new一个InputStreamReader←FileInputStream←file
* 3.用BufferedReader（←InputStreamReader）的readLine()方法读取
* */
File ctoFile = new File("C://Users//gl//Desktop//ku//51cto.txt");
InputStreamReader rdCto = new InputStreamReader(new FileInputStream(ctoFile));
BufferedReader bfReader = new BufferedReader(rdCto);
String txtline = null;
while ((txtline = bfReader.readLine()) != null) {
System.out.println(txtline);
}
bfReader.close();
};
