A bank wants you to create a GUI application that will allow bank employees to view the clients information. The application interface should have four labels and four textboxes, which are used to display first name, last name, account number and account balance respectively. The interface should also have two buttons: previous and next, which allow the bank manager to search through each client’s information backward and forward respectively. Create a customer class to represent the client with first name, last name, account number and account balance. When the GUI application is loaded, create an array of customer objects, and then display the first client’s information to the manager. (Hint: Use object initialize in the array’s initialize to create each customer object.) If the current client is the first in the array, the last client in the array is displayed when the manager clicks the previous button. If the current client is the last in the array, the first client in the array is displayed when the manager clicks the next button.
