Java: How to change the language of java.util.logging to English?

Question

I have java.util.logging to print output to a file. It works fine. However, the messages contain chinese characters which correspond to the log level and the time the messages are logged.

How can I make it print english instead of chinese characters ?

This is what the current messages look like

you can use Locale.setDefault(Locale.ENGLISH); to change the log level languages – Submiss

Answer 1

Start your application by passing the language on the command-line to override the current default language of the OS.

java -Duser.language=en MyApplication

Is there a way that I override it permanently ? I am using Eclipse to compile and run the applcation. – Evadnee

You can define an environment variable called _JAVA_OPTIONS=-Duser.language=en to make it the default value for the JVM. – Neuropathy

If you want to set it programmatically, you can put System.setProperty("user.language", "en") in a static block at the beginning of your main class (class containing the main method) – Tho

interesting blog post about it blogs.oracle.com/CoreJavaTechTips/entry/… – Tho

Locale.setDefault(new Locale("en", "EN")); works for me (and System.setProperty does not). – Swearingen
