Java File question

Is there a better way to get a file handle w/o using File file = new File(fileName);?

Is there a way to directly delete?  or a better way to instantiate?
 take a peek at the code below

Iterator it = rynList.iterator();
            
            boolean answer=false;
            boolean file_exists=false;
            try{
            while (it.hasNext())
            {
                  RData ryno = (RData)it.next();
                  
                  
                  Iterator fileIterator = ryno.getId().iterator();
                  
                  
                  while (fileIterator.hasNext())
                  {
                        String fileName = (String)fileIterator.next();
                        
                        
                        File file = new File(fileName);
                        file_exists=file.exists();
                        if (file_exists)
                        {
                              answer=file.delete();
                        }
                  }
            }
      }
            catch(Exception e)
            {
                  e.printStackTrace();
                            
           
            }


thanks

I believe not, what is the reason You don't 'like' the File class?

not me :) another developer questioned the using new.  I've looked for another way but I dont know of one...

File file = new File(fileName);

If You wonder if the usage of new creates a lot of objects and later uses the memory, then there is no need to worry, cause the garbage collection will free the unreferrenced memory blocks automatically.

Thanks for the points.
