Java-如果字符串以“ <”开头，则无法将字符串写入文件

Question

If I use the following code:

try {
        writer = new BufferedWriter(new OutputStreamWriter(
              new FileOutputStream(fileName), "utf-8"));


        writer.write("<title>");




    } catch (IOException e) {

      throw new RuntimeException(e);

    } finally {

       try {
           writer.close();
       } catch (Exception e) {
           throw new RuntimeException(e);
       }

    }

nothing shows up in the file, but if I remove the "<" , and try to output "title>" it works fine. How can I get around this?

Answer 1

The problem isn't in your code, it's in the viewer (editor) that you're using to view the output. Instead of showing you the plain plain text, it's interpreting the data in the file, and showing you its interpretation. Use a plain editor such as notepad or vi to see what is in the file.

Answer 2

Try flushing your writer after you write:

writer.write("<title>");
writer.flush();
