Java Console Output with UTF-8
Update - for newer versions of Java (17 onwards), things are a bit different. See The NetBeans Output Window - Revisited for details.
Remember:

Also, using StandardCharsets.UTF_8
rather than the literal string “UTF-8” avoids the need to handle an UnsupportedEncodingException
.
In some cases, you may also need this Java command line option:
-Dfile.encoding=UTF-8
If it’s the console used by NetBeans, add the option to the default options in:
.../netbeans/etc/netbeans.conf
Something like this (with the additional -J in this case):
netbeans_default_options="... -J-Dfile.encoding=UTF-8"
An alternative approach in NetBeans is to go to Project Properties > Run > VM Options, and add this:
-Dfile.encoding=UTF-8
After that, the System.out.println("
读写汉字")
command should work without needing the PrintStream
code.
To check what default encoding the JVM is using, use:

One final item: If you are using Windows and you want to change the command console to use UTF-8 for output, then run this command:
CHCP 65001
And make sure you are using a font which can actually display the characters you need to show.
