学习小记：
1、首先要根据路径获取你的 txt 文本文件。File file = new File(path);
2、将获取到的这个字节码流读进缓存。new FileInputStream(file) ;
3、然后对刚才读进缓存的输入流进行解读，生成对应字节流。InputStreamReader(readIn)
4、再然后通过 BufferedReader 这个类进行一行一行的输出。bufferedReader.readLine()
代码：
public static void ReadTxt () {
try {
File file = new File("E:\\text.txt");
FileInputStream readIn = new FileInputStream(file);
InputStreamReader read = new InputStreamReader(readIn, "utf-8");
BufferedReader bufferedReader = new BufferedReader(read);
String oneLine= null;
while((oneLine= bufferedReader.readLine()) != null){
System.out.println(lineTxt);
}
read.close();
} catch (Exception e) {
System.out.println("读取文件内容出错");
e.printStackTrace();
}
}
