Run Log4J program without Properties file

How run Log4j program without using Properties file?

We will write programs in two ways.

Type 1:
package com.log.appender;

import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import java.util.Properties;

public class Log4jPropr{
 static Logger log = Logger.getLogger(Log4jPropr.class);

 public static void main(String[] args) {

 Properties log4jProperties = new Properties();
 log4jProperties.setProperty("log4j.rootLogger", "INFO, myConsoleAppender");
 log4jProperties.setProperty("log4j.appender.myConsoleAppender", "org.apache.log4j.ConsoleAppender");
 log4jProperties.setProperty("log4j.appender.myConsoleAppender.layout", "org.apache.log4j.PatternLayout");
 log4jProperties.setProperty("log4j.appender.myConsoleAppender.layout.ConversionPattern", "%-5p %c %x - %m%n");
 PropertyConfigurator.configure(log4jProperties);
 log.setLevel(Level.DEBUG);

 log.debug("This is a debug message");
 log.info("This is an info message");
 }
}

Output:

DEBUG com.log.appender.Log4jPropr  - This is a debug message

INFO  com.log.appender.Log4jPropr  - This is an info message

Type-2:

package com.log.appender;

import java.io.IOException;

import org.apache.log4j.DailyRollingFileAppender;
import org.apache.log4j.FileAppender;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.PatternLayout;

public class Log
{
    public static Logger as_looger;
    public static void main(String[] args) {
    as_looger = Logger.getLogger("articles logging");
        as_looger = Logger.getLogger(Log.class.getName());
        FileAppender as_appender = null;
            try {
as_appender = new DailyRollingFileAppender(new PatternLayout("%d{dd-MM-yyyy HH:mm:ss} %C %L %-5p: %m%n"), "path of file where to write logs","'.'dd-MM-yyyy");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
        as_looger.setLevel(Level.DEBUG);
        as_looger.addAppender(as_appender);
}

}
