Pastner Brands is a calendar-year firm with operations in several countries. As part of its executive compensation plan, at January 1,
2024, the company issued 480,000 executive stock options permitting executives to buy 480,000 shares of Pastner stock for $38 per
share. One-fourth of the options vest in each of the next four years beginning at December 31, 2024 (graded vesting). Pastner elects to
separate the total award into four groups (or tranches) according to the year in which they vest and measures the compensation cost
for each vesting date as a separate award. The fair value of each tranche is estimated at January 1, 2024, as follows:

Each user can borrow up to 2 bicycles at a time, specifically for families with children 18 years or below. The system must track the bicycles (name, make, type, and availability) and users (name, ID, and borrowed bicycles). The company also wants to ensure that the system uses a multidimensional array to store information about the bicycles.

This method should return the balance of the current account after the transfer, also should check for the sufficient balance in current account before proceeding the transfer and if there is insufficient balance return an error message "Insufficient balance". Modify the BankAccount Test class, so that it calls the transfer () method and prints the balance after transfer. Make sure that the transfer() method updates the balance of both the current account and the destination account.arrow_forward• Create a public method called deposit() that takes in an amount of type double as input and adds the amount to the current balance. This method should also return the updated balance. • Create another public method called withdraw() that takes in an amount of type double as input, checks if the withdrawal amount is less than the current balance, and if so, subtracts the amount from the balance. If the withdrawal amount is greater than the current balance, the method should return an error message "Insufficient balance". • Create a public method getAccountInfo() that returns the account information in the format "Account Number: xxxxx, Account Holder: John Doe, Account Type: SAVINGS/CHECKING, Balance: $xxxX.XX". • Finally, create a constructor method that takes in the account number, account holder name, initial balance and account type as input and initializes the corresponding instance variables.
