Create a JAVA Code:

Create a JAVA code to display an image inside a frame. Add four buttons to the frame and use the buttons to move the image within the frame. The image should not go outside the frame. The image should be able to move left, right, up, down. Use repaint() to redraw the image after you have moved it.
