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…

Create a file called contacts.py, implement a program that prompts the user to select a choice between these 5 options. Add contact (1), Delete Contact (2) Save Contact(3), show all contact (4), exit program (5). Contact info should be saved in a separate read/write file. If user inputs number (1) on the keyboard, then prompt them to input the name and number of the contact. If user selects (2), delete all contacts or show an error if there are no contacts saved to file. If user inputs (3) save the contact and loop the choice of the 5 options until user inputs (5) to exit. If user inputs (4) print out the saved contacts to the screen neatly, Name, Number(newline). if user inputs 5 then exit the program. If the user inputs a number not shown then give an error message and ask them to input a valid number.  Please code in python, preferably using case statements to complete
