Java provides logging APIs like: Logger, Level, Handler etc. for implementing logging features in your java application. It is a part of J2SE (Java 2 Standard Edition). To create java logging program you need a Logger object. The Logger object contains log messages. Logger has one or more handler that performs log records. Java logging provides a way to contain multiple types of message like: warning, info, severe etc. for an application. These information or messages can be used for many purposes but it is specially used for debugging, troubleshooting and auditing.
