The original file is CRLF, but I wanted it to be LF only. The character code is UTF-8 for both input and output.

environment

OS：Windows8.1 Pro Java Version: jre1.8

Prerequisites

See this article for file input / output.

//At the end of the record\Grant LF.

    bf.append(msg);
    bf.append("\n");

Supplementary explanation

• You can revert to the Windows line feed code by changing \ n to \ r \ n.
• If you search on the net, there are various methods such as replacing with replaceAll or using a regular expression, but it seems that it can be realized even with the above. Is it strictly this method?
