Assume a class named BankAccount exists, containing the following methods: • a constructor that accepts a String containing the name of the account holder • a public method named getBalance that returns the account balance as a double • a public method named withdraw that accepts a double argument and deducts the amount from the account balance Write the definition of a class named CheckingAccount, that is a subclass of BankAccount. The CheckingAccount class should contain: • a boolean field named overdraft. (If overdraft is true, checks that are larger than the current account balance can be written.) • a constructor that accepts a String and a boolean. The String parameter contains the account holder's name and should be passed to the superclass (BankAccount) constructor. The boolean parameter should be used to initialize the overdraft field. • a public method named hasOverdraft, that returns a boolean. The method should return the value of the overdraft field. • a public method named clearCheck that accepts a double argument and returns a boolean. The argument is the amount of a check. The method should determine whether 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, the clearCheck method returns true, and also calls the withdraw method to update the account balance; otherwise, the clearCheck method returns false.

java

Assume a class named BankAccount exists, containing the following
methods:
• a constructor that accepts a String containing the name of the account
holder
• a public method named getBalance that returns the account balance as a
double
• a public method named withdraw that accepts a double argument and
deducts the amount from the account balance
Write the definition of a class named CheckingAccount, that is a subclass
of BankAccount. The CheckingAccount class should contain:
• a boolean field named overdraft. (If overdraft is true, checks that are
larger than the current account balance can be written.)
• a constructor that accepts a String and a boolean. The String parameter
contains the account holder's name and should be passed to the superclass
(BankAccount) constructor. The boolean parameter should be used to
initialize the overdraft field.
• a public method named hasOverdraft, that returns a boolean. The
method should return the value of the overdraft field.
• a public method named clearCheck that accepts a double argument and
returns a boolean. The argument is the amount of a check. The method
should determine whether 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, the clearCheck
method returns true, and also calls the withdraw method to update the
account balance; otherwise, the clearCheck method returns false.
