BufferedWriter没有写入文本文件 [英] BufferedWriter not writing to text file

问题描述

所以我正在使用 BufferedWriter ，并希望将一些文本写入文本文件。

So I'm using a BufferedWriter and would like to write some text to a text file.

try {
   BufferedWriter b = new BufferedWriter(new FileWriter ("/home/usr/Desktop/logger/logs.txt"));
   b.write("hello");
} catch (Exception e1) { e1.printStackTrace(); }

由于某种原因，正在创建文本文档但没有写入任何内容，为什么这样？

For some reason the text document is being created but nothing is being written to it, why is this?

推荐答案

您需要关闭 BufferedWriter ，或使用 try-with-resource

BufferedWriter b = new BufferedWriter(
new FileWriter ("/home/usr/Desktop/logger/logs.txt"));
b.write("hello");

//After writing close the resource
b.close();
