java.util.logging: Remove date time line

Question

I currently have this code in my main().

Logger logger = Logger.getLogger("My Log");
FileHandler fh;
logger.addHandler(fh);
SimpleFormatter formatter = new SimpleFormatter();
fh.setFormatter(formatter);
logger.info("Test");

This outputs 2 lines. One with datetime, and the other is test. I read many other questions on this site, but i do not get how to implement it to my current code.

UPDATE: I have created a new file called logging.properties and updated Logger logger = Logger.getLogger("logging.properties");

Inside the file i inputted these values

handlers= java.util.logging.ConsoleHandler
.level= INFO
java.util.logging.ConsoleHandler.level = INFO
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
javax.jms.connection.level = INFO
java.util.logging.SimpleFormatter.format=[%1$tF %1$tr] %3$s %4$s:  %5$s %n

But when i run i still see the date line. What am i missing?

You need to add a file called logging.properties to your Java project. In there, you can define the format to be used:

java.util.logging.SimpleFormatter.format=[%1$tF %1$tr] %3$s %4$s:  %5$s %n

The documentation here explains what the %... specifiers mean: http://docs.oracle.com/javase/7/docs/api/java/util/Formatter.html#syntax

If you want to do it programatically, you could do 2 things:

Implement a custom formatter and set to handler: fh.setFormatter(new MyCustomFormatter()); See http://examples.javacodegeeks.com/core-java/util/logging/create-custom-formatter-for-logger-handler/
If you want only 1 line, the workaround is explained here: java.util.logging: how to suppress date line
