I wrote a sample code to work with the log4j library, but I encountered an error as mentioned below. Additionally, a new log4j file isn't being created. Can anyone help me understand why this error is occurring?

What I have tried:

This is my class file

package log4j_testing;

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;

public class log4jexample {
static Logger logger=Logger.getLogger(log4jexample.class);
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		logger.debug("this is a debug");"this is an info");
		logger.warn("this is a warning");



and this is my log4j.propertiesfile

log4j.rootLogger=INFO , file

log4j.appender.file.File=D:\1.SUBJECTS\SEMESTER 07\SELF_QA\LOg4jExamplefiles\logging.log
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
