What is 212o fahrenheit in celsius?

A good answer might be:

Boiling temperature is 212o fahrenheit; 100o in celsius.

Design of an Application

We will design and implement a GUI application that converts a temperature expressed in fahrenheit into celsius. Two things have to be designed:

  1. The actual application.
  2. The user interface to the application.
Let us first look at the application. The formula for converting fahrenheit into celsius is this: 
celsius = (fahrenheit - 32) * 5/9
This is algebra, not Java. Although the algebra looks a lot like Java some more design decisions are needed.

QUESTION 2:

Should the Java program use integer variables or floating point variables to implement the formula?
