Different Size of Font MIDlet Example

This example simply shows the different size of font. There are three attributes are used for the different font sizes. That are:

Font.SIZE_LARGE);
Font.SIZE_MEDIUM);
Font.SIZE_SMALL);

The SIZE_LARGE is used to large size of font, the SIZE_MEDIUM is used to medium size of font and the SIZE_SMALL is used to small size of font, which shows in the mobile figure below:
