What type of data goes into your program? Could the user get this data incorrect? For instance, what if they put letters instead of a number? What if they used negative numbers? It’s time to start building exception code for your program. What do you need to anticipate potential crashes in your program? You should now be writing the code for your program and adding in error handling. It will help to plan out the exception handling. Consider that the program should not crash if the following occurs:  What protects bad user inputs? (numbers instead of letters and vice versa) What if nothing is entered? How is that handled? Can the user cause your program to divide by zero? What if the user inputs lower case instead of uppercase and vice versa? (for instance, "y” instead of “Y” for yes response) With the considerations above clarified, use any program that has UML capability to make your flowcharts in UML.

I have an idea and would appreciate some help. Here is my idea:

What is my program supposed to do: . I want to be able to create a program that can extract a player's name based on the sport I decide to choose (either football, basketball, or baseball) and have them be placed on the user's team where they can choose to keep them or remove them from said team. As the season progresses the user will go into the program and input the stats of their players and the program will calculate their fantasy performance based on what the user inputs. The user may also be able to put in, take out, or adjust any stats that are calculated at any time during the season. The user will also take the players and be able to choose from a number of options on what to do with them. I hope to either make it so that multiple users can "play" at the same time against one another with the program, if not then I may try to input at least one other team controlled by the program so that there would be some competition. If not, then the program will be utilized more as a database for the user to input and compare whatever statistical categories they want and compare players using it

1. You should now be writing the code for your program and adding in error handling. It will help to plan out the exception handling.
2. Consider that the program should not crash if the following occurs: 
   • What protects bad user inputs? (numbers instead of letters and vice versa)
   • What if nothing is entered? How is that handled?
   • Can the user cause your program to divide by zero?
   • What if the user inputs lower case instead of uppercase and vice versa? (for instance, "y” instead of “Y” for yes response)
3. With the considerations above clarified, use any program that has UML capability to make your flowcharts in UML.
