Boiling temperature is 212o Fahrenheit; 100o in Celsius.
Let's design and implement a GUI application that converts a temperature expressed in Fahrenheit into Celsius. As usual, there are three parts to the design:
Let us first look at the application methods. The formula for converting fahrenheit into Celsius is this:
celsius = (fahrenheit - 32) * 5/9
This is algebra, not Java. Although the algebra looks much like Java some more design decisions are needed.
