package java.util.logging;

This Handler publishes log records to System.err. By default the SimpleFormatter is used to generate brief summaries. 

Configuration: By default each ConsoleHandler is initialized using the following LogManager configuration properties where <handler-name> refers to the fully-qualified class name of the handler. If properties are not defined (or have invalid values) then the specified default values are used. 

 <handler-name>.level specifies the default level for the Handler (defaults to Level.INFO). 
 <handler-name>.filter specifies the name of a Filter class to use (defaults to no Filter). 
 <handler-name>.formatter specifies the name of a Formatter class to use (defaults to java.util.logging.SimpleFormatter). 
   <handler-name>.encoding
       the name of the character set encoding to use (defaults to
       the default platform encoding). 

 For example, the properties for ConsoleHandler would be: 

   java.util.logging.ConsoleHandler.level=INFO 
   java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter 


For a custom handler, e.g. com.foo.MyHandler, the properties would be:

   com.foo.MyHandler.level=INFO 
   com.foo.MyHandler.formatter=java.util.logging.SimpleFormatter
