Access Util.logger from multiple classes

Question

I'm new to util.logging so this might seem a trivial question to some but anyway here goes..I'm using Java's Util.logger to log messages. I'm trying to declare a logger in a single class and accessing it from other classes for logging messages.

Logger class

package util;

import java.util.logging.*;

public class Logger {

public Logger LOGGER = Logger.getLogger(Logger.GLOBAL_LOGGER_NAME);

 }

I'm trying to access this logger in other class as follows..

package mycode;

import util.Logger;

public class MYcode{

private void test(){
 LOGGER.fine("Sample message");
}
}

Compilation Error message..

error: cannot find symbol
[javac]LOGGER.fine("Sample message");

When I'm declaring logger in Mycode class then I'm not getting any error but when declaring it another class I'm getting an error. Any idea where I'm going wrong??

`LOGGER` is not static here so you can't call it that way. If it were you'd either need to do a static import of `util.Logger.LOGGER` (`import static ...`) or access it via `Logger.LOGGER`. — Thomas, Mar 04 '16 at 12:18

Just keep using in all classes needing the logger the same line:

public Logger LOGGER = Logger.getLogger(Logger.GLOBAL_LOGGER_NAME);

This way you are creating many references to one instance of logger identified by the global name.

I need to use the above line only once to simplify the code..any idea how to do it? – Lucy Mar 04 '16 at 12:26
make `LOGGER` `static` and `final` and you can use it by calling `Logger.LOGGER.fine("msg")` – diginoise Mar 04 '16 at 12:28

The problem is your 'LOGGER' is NOT static, so you are NOT able to access.

Logger class:

package util;

import java.util.logging.*;

public class Logger {

public static final Logger LOGGER = Logger.getLogger(Logger.GLOBAL_LOGGER_NAME);

 }

Accessing logger in other class:

package mycode;

        import util.Logger;

        public class MYcode{

        public void test(){
         LOGGER.fine("Sample message");

        }    
    }

By mistake I made test method public in my question.It's actually private, I've edited my question accordingly..will your answer work then also?? – Lucy Mar 04 '16 at 12:32
