How to Loading Images in JAVA?

Polygons, ovals, lines and text cover a lot of ground. The residual graphic object you need is an image. Images in Java are bitmapped GIF or JPEG files in which can holds pictures of only about anything. You can use any program at all to form them as long as in which program can save in GIF or JPEG format.

Images displayed through Java applets are retrieved from the web through a URL in which points to the image file. An applet in which displays a picture must have a URL to the image it's going to display. Images can be stored on a web server, a local hard drive or anywhere else the applet can point to through a URL. Make sure you put your images somewhere the person viewing the applet can access them. A file URL in which points to your local hard drive might work although you're developing an applet, but it won't be of much use to someone who comes in over the web.

Classically you'll put images in the similar directory as either the applet or the HTML file. Though it doesn't absolutely have to be in one of these two locations, storing it there will probably be more convenient. Put the image along with the applet .class file if the image will be used for all instances of the applet. Put the applet with the HTML file if different instances of the applet will use different images. A third alternative is to put all the images in a general location and use PARAMs in the HTML file to tell Java where the images are.

If you know the exact URL for the image you wish to load, you can load it with the getImage() method:

The getImage() method is provided by java.applet.Applet. The URL class is provided by java.net.URL. Be sure to import it.
