## java.util.logging
Class ConsoleHandler

    java.lang.Object
      java.util.logging.Handler
          java.util.logging.StreamHandler
              java.util.logging.ConsoleHandler

    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. If properties are not defined (or have invalid values) then the specified default values are used.

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

Constructor Detail

### ConsoleHandler

    public ConsoleHandler()

  Create a `ConsoleHandler` for `System.err`.

  The `ConsoleHandler` is configured based on `LogManager` properties (or their default values).

Method Detail

### publish

    public void publish(LogRecord record)

  Publish a `LogRecord`.

  The logging request was made initially to a `Logger` object, which initialized the `LogRecord` and forwarded it here.

  Overrides:
    `publish` in class `StreamHandler`
  Parameters:
    `record` - description of the log event. A null record is silently ignored and is not published

### close

    public void close()

  Override `StreamHandler.close` to do a flush but not to close the output stream. That is, we do not close `System.err`.

  Overrides:
    `close` in class `StreamHandler`
