ImageIO.write not working?

I'm writing a 3D paint and I found a problem in java. In one part of the code it's working: ``` try { ImageIcon savePane=new ImageIcon("save.png"); String FilePath= (String)JOptionPane.showInputDialog(null,"Enter file path and name\n Warning: Instead of one '\\' write '\\\\'", "Save",JOptionPane.PLAIN_MESSAGE,savePane,null,"C:\\\\example.png"); BufferedImage image = new Robot().createScreenCapture(new Rectangle(110,130,put.getWidth()-3,put.getHeight())); ImageIO.write(image, "png", new File(FilePath)); System.out.println(FilePath); } catch (IOException e) { e.printStackTrace(); } catch (HeadlessException e) { e.printStackTrace(); } catch (AWTException e) { e.printStackTrace(); } ``` While in another one it isn't working: ``` try { String UndoFolder= "was.png"; BufferedImage image = new Robot().createScreenCapture(new Rectangle(110,130,put.getWidth()-3,put.getHeight())); ImageIO.write(image, ".png",new File(UndoFolder)); } catch (IOException e1) { e1.printStackTrace(); } catch (AWTException e1) { e1.printStackTrace(); } catch (HeadlessException e3) { e3.printStackTrace(); } ``` Can you tell me how to make it work? Thanks Before you ask, yes it does execute that part of the code, I checked. Edit: Ohhh working fine now thanks
