Parsing a string A string is a sequential object that has zero, one or many characters. This lab asks you to ask the user for a string and then count the number of digits in the string.

NOTE: You must do this with a WHILE loop, not a FOR.

How can you tell if a character is a digit? If you have a string variable named str, you. can make a Boolean expression that will be True by doing this: str. isdigit() So if I code: str="spam" then str. isdigit() will be False But if I code: str =. "1984" then str. isdigit() will evaluate to True.

The strings will have digits and non-digits mixed. You must look at each character of the string by itself. You do this by indexing the string. If i is an index variable, then str[i] will give you the character at the i-th position in the string (remembering that it is indexed from zero).

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.
