I guess my biggest issue is actually to draw a functionable applet. Design an applet Conversion.java that converts a character to a corresponding integer, and vice versa. The integer corresponding to a character is its ASCII code. The design should look as the attached picture. The applet has to have the following functio
Define a class called Fraction, used to represent a ratio of two integers. 1. Include mutator functions that allow the user to set the numerator and the denominator. 2. Also include a METHOD that displays the fraction on the screen as a ratio (e.g., 5/9). This method does not need to reduce the fraction to lowest terms. 3.
