Rename logger at runtime based on user input

Question

As the title says, I have a Logger object logger, in a class classname the definition of classname contains a vararg String v. If v does exist, logger should be named that, else it should have a default. How should I do this? My code:

final Logger logger=null;
    if(globalLogger!=null){
        logger.getLogger(globalLogger);
    }
    else{
      logger.getLogger(ImportThread.class.getName());
    }

This returns:The static method getLogger(String) should be accessed in a static way. Is this possible? If not, how should I go about this?

You should specify which Logger class you are using. From the current info it seems to me the Logger logger variable should be static

static final Logger logger=null;

Note sure about the rest of the code but this should at least fix the "should be accessed in a static way" issue

This change gives an **Only one final allowed** error. – Cole Christini Dec 02 '17 at 05:43
you should not declare it as final, assign it null and then try to change the reference. Refer [this question](https://stackoverflow.com/q/15655012/1304575) and API docs on more info on the final keyword – suvartheec Dec 02 '17 at 06:41
Ok, but it also say only final allowed. – Cole Christini Dec 02 '17 at 06:44
Please post the complete error message. No way for anyone to help unless they know what is happening. – suvartheec Dec 02 '17 at 06:45
That went away, but the original error message: file: 'The static method getLogger(String) from the type Logger should be accessed in a static way' is still here – Cole Christini Dec 02 '17 at 06:49

access it statically means you call it as method of the class:

Logger logger=null;

if(globalLogger!=null){
    logger = Logger.getLogger(globalLogger);
} else{
  logger = Logger.getLogger(ImportThread.class.getName());
}

In your code, you did not use what Logger.getLogger() returned, I changed to an assignment; with this code you cannot make it final, because you cannot reassign a final variable.
