Java Copy File

import java.io.*;
import java.util.*;
public class CopyFile{
  private static void copyfile(String srFile, String dtFile){
    try{
      File f1 = new File(srFile);
      File f2 = new File(dtFile);
      BufferedReader br=new BufferedReader(new FileReader(f1));
      BufferedWriter bw=new BufferedWriter(new FileWriter(f2,true));

     String line="";
      while ((line = br.readLine())!=null){
        bw.write(line.toUpperCase());
      }
      bw.close();
      System.out.println("File copied.");
    }

    catch(IOException e){
      System.out.println(e.getMessage());      
    }
  }
  public static void main(String[] args){
   Scanner input=new Scanner(System.in);
   System.out.print("Enter source file with path: ");
   String file1=input.next();
   System.out.print("Enter destination file with path: ");
   String file2=input.next();
   copyfile(file1,file2);
