Java I/O:如何追加到已经存在的文本文件

Java I/O: How to append to an already existing text file(Java I/O:如何追加到已经存在的文本文件)

问题描述

您好，我在写入或附加到文件时没有问题，唯一的问题是，一旦我退出程序然后再次运行它，它会创建一个覆盖我原始文件的新文件.这是一个问题，因为我正在使用文本文件来保持运行记录.

Hi I am having no problem writing to or appending to a file, the only problem is that as soon as I quit the program and then run it again, it creates a new file overwriting my original file. This is a problem, as I am using the text file to keep a running tally.

有没有办法将已创建的文本文件作为对象获取然后附加到它?

Is there a way to get an already created text file as an object and then append to it?

提前致谢.

FileWriter 有一个构造函数，它允许您使用布尔值设置附加.javadoc
