How to Use FileWriter to write UTF-8

FileWriter cannot write UTF-8. I believe many new users have met FileWriter. let's solve this problem today. Let's look at the example below.

Package cn. yethyeth. sample. io;
Import java. io. FileNotFoundException;
Import java. io. FileOutputStream;
Import java. io. IOException;
Import java. io. OutputStreamWriter;
Import java. io. UnsupportedEncodingException;
/***//**
* The file name is FileWriterSubstituteSample, which is actually a replacement for FileWriter.
* When FileWriter writes a file, the encoding method seems to be System. encoding or System. file. encoding,
* In the Chinese win encoding is basically gb2312, In the win en is basically iso-8859-1, in short not UTF-8.
* Therefore, you cannot use FileWriter to create a UTF-8 file.
* Currently, you do not know how to change the encoding method used to write files. Therefore, you can use the following method to create a UTF-8 file.

New FileOutputStream (path), "UTF-8 ");

Out. flush ();
Out. close ();
System. out. println ("success ...");
