public class ConsoleHandler extends StreamHandler
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 toLevel.INFO
). - <handler-name>.filter specifies the name of a
Filter
class to use (defaults to noFilter
). - <handler-name>.formatter specifies the name of a
Formatter
class to use (defaults tojava.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

- 1.4
