Write a class definition for a subclass, CheckingAccount, that contains: a boolean instance variable, overdraft. (Having overdraft for a checking account allows one to write checks larger than the current balance). a constructor that accepts a String and a boolean. The String parameter is used in the invocation of the superclass (BankAccount) constructor, while the boolean is used to initialize the overdraft instance variable. a method, hasOverdraft, that returns a boolean. hasOverdraft returns true if the account supports overdraft. a method, clearCheck, that accepts a double and returns a boolean. clearCheck will determine if the amount (of the check) can be cashed-- this will be the case if the amount is less than the balance in the account, or if the account allows overdraft. If the check can be cashed, clearCheck returns true, and also calls the withdraw method to update the account balance; otherwise, clearCheck returns false.

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)
