Java - Copying one file to another

Here is function called copyFile  which takes 2 strings – source and destination. It copies source to destination.

 

private static void copyFile(String srcFile, String dstFile){

  try{

    File f1 = new File(srcFile);

    File f2 = new File(dstFile);

    InputStream in = new FileInputStream(f1);
 
//Append the file
    OutputStream out = new FileOutputStream(f2,true);
//Overwrite the file.
    OutputStream out = new FileOutputStream(f2);


      byte[] buf = new byte[1024];

     int len;

     while ((len = in.read(buf)) > 0){

        out.write(buf, 0, len);

   }

   in.close();

    out.close();

   System.out.println("File copied.");

  }

  catch(FileNotFoundException ex){
    
       System.out.println(ex.getMessage() + " in 
                          the specified directory.");
       return false;
       
  }

 catch(IOException e){

  System.out.println(e.getMessage());  
  return false;
  
  }
    return true;
}
