Logger logger = Logger.getLogger("com.example.myapp"); logger.setLevel(Level.FINER); if (logger.isLoggable(Level.FINER)) { logger.finer("This is a finer level log message"); }
Logger logger = Logger.getLogger("com.example.myapp"); logger.setLevel(Level.FINER); try { // some code that throws an exception } catch (Exception e) { logger.log(Level.FINER, "Exception caught", e); }This code creates a logger for the com.example.myapp package and sets the log level to finer. The log() method is used to write a log message with the finer level, along with the exception that was caught. Overall, the java.util.logging package library provides a powerful and flexible logging framework that can be used to effectively manage logging information in Java applications.
