java log
// Java program to illustrate logging in Java
// The following code shows a basic example how logging
// works in Java
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.*;
class DemoLogger {
private final static Logger LOGGER =
Logger.getLogger(Logger.GLOBAL_LOGGER_NAME);
// Get the Logger from the log manager which corresponds
// to the given name <Logger.GLOBAL_LOGGER_NAME here>
// static so that it is linked to the class and not to
// a particular log instance because Log Manage is universal
public void makeSomeLog()
{
// add some code of your choice here
// Moving to the logging part now
LOGGER.log(Level.INFO, "My first Log Message");
// A log of INFO level with the message "My First Log Message"
}
}
public class GfG {
public static void main(String[] args)
{
DemoLogger obj = new DemoLogger();
obj.makeSomeLog();
// Generating some log messages through the
// function defined above
LogManager lgmngr = LogManager.getLogManager();
// lgmngr now contains a reference to the log manager.
Logger log = lgmngr.getLogger(Logger.GLOBAL_LOGGER_NAME);
// Getting the global application level logger
// from the Java Log Manager
log.log(Level.INFO, "This is a log message");
// Create a log message to be displayed
// The message has a level of Info
}
