//Lab 2
//Debugging Problem (a)

// The program is about converting temperature from Fahrenheit to Celsius and vice versa.
// 1. You are not allowed to rewrite the whole program.
// 2. After finishing debugging, comment the code.
// 3. You may need to reference the Java API page (http://java.sun.com/j2se/1.4.2/docs/api/) for explainations of some 
//    of the methods and classes used in the program.
// 4. You will be asked questions when your lab instructor/GA evaulates your work.
