问题描述

如何从.txt文件中读取和显示数据？

How do you read and display data from .txt files?

推荐答案

BufferedReader in = new BufferedReader(new FileReader("<Filename>"));

然后，你可以使用in.readLine（）;一次读一行。要读到最后，请写一个while循环：

Then, you can use in.readLine(); to read a single line at a time. To read until the end, write a while loop as such:

String line;
while((line = in.readLine()) != null)
{
    System.out.println(line);
}
in.close();
