I am using java.util.logging package to create log files.
I have to generate log files and append to the file based on the condition.
When i am writing message to single log file it it updated to all the log files.
Code
==========================
//To create error_0.log file
import java.util.logging.FileHandler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;
public class NetLogger
     private String pattern = "./log/error_%g.log";
     private int limit = 1000000; // 1 Mb
     private int numLogFiles = 300;
     private FileHandler fh = null;
     private Logger logger =null;
public NetLogger()
     try
          fh = new FileHandler(pattern, limit, numLogFiles);
          fh.setFormatter(new SimpleFormatter());
          logger = Logger.getLogger("com.netenforcers");
               logger.setUseParentHandlers(false);
          logger.addHandler(fh);
          //logger.setLevel(Level.ALL);
     catch(Exception ex)
          ex.printStackTrace();
public Logger getLogger()
     return this.logger;

// To create whoIs_0.log
import java.util.logging.FileHandler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;
public class WhoIsLogger
     private String pattern = "./log/whoIs_%g.log";
     private int limit = 1000000; // 1 Mb
