If the Javagochi feels well, its skin has a bright yellow color. The difference between Display and Displayable is that the Display class represents the display hardware, whereas Displayable is something that can be shown on the display.

The drawImage method in Graphics requires an Image object, the coordinates, and an integer cojrs the alignment as parameters. For initializing the Listthe lcdui packages offers constructors. For that reason, another static create method, createImage Image imageis provided that creates an immutable cours j2me from cours j2me image.
