Question
[画像:You will develop a client side and a Servlet program that will work with a database. 1. The client (front end) should have a title "NJIT Credit Union", centered. 2. The client should have a background color. 3. The client should have a text field with label 'UserID' where user will enter userID (integer) and a Submit button with text "Submit". 4. An unsuccessful authentication should have a message printed on the screen, in red, stating that "Your authentication has failed, please try again." (no pop up message). At this point the text field should get cleared and ready to accept a new input. Your program should not exit. 5. A successful authentication should be followed by a message on the screen, in green, stating that "Your authentication is successful" (no pop up message). 6. There should be two other text boxes with label "Deposit" and "Withdraw" where user will enter an amount (you should accommodate for decimals). These two text boxes should only be enabled after successful authentication and the initial values will be blank. You have the choice to use either text boxes or radio buttons or check boxes - whatever is suitable for you. 7. If a deposit is made, there should be a message on the screen, in green, with the current balance which should include the deposited amount. 8. For withdrawal, you must check if the amount is available, if not available, print a message on the screen, in red, stating that "There is insufficient funds, please try a smaller amount". The text field should clear and be ready to accept a new amount. If fund is available, go ahead with the transaction and print current balance on the screen, in green. 9. Database info: A. Create a database "ATM" B. Create a table accountInfo" in that database with the following: Name Balance Jane 2270.25 John 903.65 userID 101 102]
