 public class SocketHandler extends StreamHandler Simple network loggingHandler.LogRecordsare published to a network stream connection. By default theXMLFormatterclass is used for formatting.Configuration: By default each SocketHandleris initialized using the followingLogManagerconfiguration 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.ALL).
-    <handler-name>.filter
        specifies the name of a Filterclass to use (defaults to noFilter).
-    <handler-name>.formatter
        specifies the name of a Formatterclass to use (defaults tojava.util.logging.XMLFormatter).
- <handler-name>.encoding the name of the character set encoding to use (defaults to the default platform encoding).
- <handler-name>.host specifies the target host name to connect to (no default).
- <handler-name>.port specifies the target TCP port to use (no default).
 For example, the properties for SocketHandlerwould be:- java.util.logging.SocketHandler.level=INFO
- java.util.logging.SocketHandler.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
 The output IO stream is buffered, but is flushed after each LogRecordis written.- Since:

Constructor Detail- 
SocketHandlerpublic SocketHandler() throws IOExceptionCreate aSocketHandler, using onlyLogManagerproperties (or their defaults).- Throws:
- IllegalArgumentException- if the host or port are invalid or are not specified as LogManager properties.
- IOException- if we are unable to connect to the target host and port.
 
 - 
SocketHandlerpublic SocketHandler(String host, int port) throws IOException Construct aSocketHandlerusing a specified host and port. TheSocketHandleris configured based onLogManagerproperties (or their default values) except that the given target host and port arguments are used. If the host argument is empty, but not null String then the localhost is used.- Parameters:
- host- target host.
- port- target port.
- Throws:
- IllegalArgumentException- if the host or port are invalid.
- IOException- if we are unable to connect to the target host and port.
