Logger in Java - Using this we can generate seperate log files for each test script

package data;

import java.io.File;
import java.io.PrintWriter;
import java.util.Date;

public class PrintWriterMethods {
   
    public static String filename="";
    public static PrintWriter pw= null;
    public static File file =null;
    public static String resultsFolder = "src/results/";
   
    public static boolean startLogger()
    {
        boolean flag = false;
        try{
            Date dt= new Date();
            String dt1 = dt.toString().replace("-", "_").replace(":", "_").replace(" ", "");
            System.out.println(dt1);
            filename = "summary"+ dt1 + ".txt";
            file = new File(resultsFolder + filename);
            pw = new PrintWriter(file);                       
            flag = true;
        }
        catch(Exception oExp){
            System.out.println(oExp.getMessage());
        }
        return flag;
    }
   
    public static String getFileName(){
        return filename;
    }
   
    public static void logFailer(String message){
        Date dt= new Date();
        pw.append(dt.toString() + "--FAILURE--" + message + "\r\n");
       
    }
    public static void closeLogFile(){
        Date dt= new Date();
        pw.append(dt.toString() + "--END OF THE SCRIPT--");
        pw.close();
    }
    public static void logSuccess(String message){
        Date dt= new Date();

        pw.append(dt.toString() + "--WARNING--" + message + "\r\n");
    }
