试试这个：

Hi,

Try this:

FileWriter writer = new FileWriter("file.txt");
writer.write("Some text to append...");
writer.close();

如果文件包含This is text。，并且如果执行此代码，那么您的文本文件将包含此内容：

If a file contains "This is text.", and if you execute this code, then your text file will contain this:

This is text.Some text to append...

如果你想要一个新的一行这是文本，然后使用转义序列换行：

If you want a new line after "This is text", then use the escape sequence for a new line:

FileWriter writer = new FileWriter("file.txt");
writer.write("\nSome text to append...");
writer.close();

在这种情况下，你的文本文件将包含：

In that case, your text file will contain this:

This is text.
Some text to append...

希望这会有所帮助。

Hope this helps.
