用Java编写文件 [英] Writing to a File in Java

问题描述

我对Java真的很陌生，因为某些原因，我无法写入文件，我的代码如下所示：

  FileWriter fstream; 
尝试{
 fstream = new FileWriter（fileLocation）; 
 BufferedWriter out = new BufferedWriter（fstream）; 
 log.info（测试应该被写入文件）; 
 out.write（test）; 
 
 out.flush（）; 
 out.close（）; 
 $ b $ catch（IOException e）{
 log.error（File not created，e）; 
} 
  

当我进入fileLocation时，我看到我的文件，但是它是空的。我的日志确实说测试应该被写入文件

我在这里做错了什么？

谢谢！

更新：我的FileLocation变量是一个字符串：

  private String fileLocation =/ Users / s / out.txt;

解决方案

代码很好。你正在检查正确的文件位置？也许你已经创建了你之前检查的文件;而你的程序可以在其他地方写。

I'm really new to Java, and I can't write to a file for some reason, my code looks like this:

FileWriter fstream;
    try {
        fstream = new FileWriter(fileLocation);
        BufferedWriter out = new BufferedWriter(fstream);
        log.info("test was supposed to be written to the file");
        out.write("test");

        out.flush();
        out.close();

    } catch (IOException e) {
        log.error("File not created ", e);
    }

When I go to the fileLocation, I see my file, but it's empty. My log does say "test was supposed to be written to the file"

What could I be doing wrong here?

Thanks!

UPDATE: My FileLocation variable is a string:

private String fileLocation="/Users/s/out.txt";

I'm using a Mac

解决方案

Code is fine. Are you checking the right file location? Perhaps you had created the file you're checking before; while your program could be writing elsewhere.
