One thing we might want to know, given an input to a chatbot, is if the input is a question.
We are going to use a very simple heuristic to check this: we will consider any input that has a question mark ('?') in it to be a question.
To do so, write a function called is_question.
This function should have the following inputs, outputs, and internal procedures:
Input(s): input_string - string
Output(s): output - boolean
Procedure(s): if there is a '?' in input_string, set output to True
otherwise, set output to False.
return output

Match the items with their respective descriptions.

File account.java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
