Java -- handler class

I have never been clear about Java handler and Android handler. Today I leave it empty. I have read the API and the source code, and I will write it at random.

The handler class in Java directly inherits from the object class. The JDK 1.6 API describes handler as follows:

Public abstract classHandlerExtends object

java.lang.Object  java.util.logging.Handler

Directly known subclass:

Memoryhandler, streamhandler

HandlerObject slaveLoggerAnd export the log information. For example, it can write the information to the console or file, send the information to the Network Log service, or forward it to the operating system log.
