Error with ImageIO

This is my code for encryption and to load image. i got this error while compiling

ImageIO.write(images, "png", bin);

Code:

Anyone can help????

what was the error message?

encrypt.java:128: cannot find symbol
symbol : method write(java.io.File,jav
location: class javax.imageio.ImageIO

it means the method 'write' doesn't exist, or maybe it does but you used it with incorrect parameters so Java didn't recognise the method signature.

Code:

---

ImageIO.write(images, "png", bin);

---

Code:

---

static boolean write(RenderedImage im, String formatName, File output)
          Writes an image using an arbitrary ImageWriter that supports the given format to a File.
static boolean write(RenderedImage im, String formatName, ImageOutputStream output)
          Writes an image using the an arbitrary ImageWriter that supports the given format to
          an ImageOutputStream.
static boolean write(RenderedImage im, String formatName, OutputStream output)
          Writes an image using an arbitrary ImageWriter that supports the given format to an OutputStream.

your variable 'images' is of the type java.io.File, but what you need is a RenderedImage type
