Change this :

FileHandler fh = new FileHandler("C:/temp/test/MyLogFile.log");

to this 

FileHandler fh = new FileHandler("C:/temp/test/MyLogFile.log", true);

If you read the documentation you will see that the second argument specifies the optional append argument. When true you will write at the end of the (existing) file, without overwriting it.

See documentation
