Java supports only the following formats for images by default,
- JPEG
- PNG
- BMP
- WEBMP
- GIF
Other than that, if we attempt to work with an image file that is different from the above-mentioned formats, your application will not be able to read or understand it and it will throw a NullPointerException when we access the BufferedImage variable. Java implements a particular type of object which is called 'BufferedImage' for images in Java and classes required in Java to perform the read and write operations. For that, we must import the file class first. BufferedImage is nothing but it is a subclass of the image class and it is used to manipulate and handle the image data. It is made up of the ColorModel of image data.
