Assignment:
How to create a Java program in eclipse that should have main menu displayed to the user when the program starts run. The main menu should have options for the user to "(1) Sign-Up (2) Log-In (3) Exit.
(1) Sign-Up option - at the sign-up menua) User should have to input first Name, last Name, current User Balance, address, password and email. There should be generate random user ID # provided assigned to user. user ID must be a string - all user data are strings.
Note: user ID would need TWO parts: (1) a char 'S' for index 0 of userID, and (2) rest is a long datatype generate from a long type method called get Random Part for creating a 8 digit number between 64_000_000 & 66_000_000. So the parse would be "S65458256" for example. All user data should be collected in an array.
a) The array of user data should be sent to a method for verification of user data in the array. This technique would allow data to be "Sent-for Storing-Now and Checked-Later". Note: You must validate all user inputs
First Name and last Name should use the same method called is Name(first Name or last Name) to verify a string for a name that has length of 4-20 letters only (A-Za-z).
Current User Balance is used as pre-loaded currency, money. current User Balance value is a method called first Last Names Char Value(first Name, last Name), which returns the sum of each all characters from first Name and last Name concatenated. So if my first Name = "Bob" & last Name = "Smith" , then current User Balance = 528. By totaling character at index in a loop that cycles concatenation of first Name and last Name combine length. Send data back to user if current User Balance is not higher than "0".
So if address (for example) does not have spaces "David" then this might not be an address, so send data back to user to correct. Help, the user experience, by trying to think for the user in case that user might make a mistake.
password must be at least 8 characters, must have at least one uppercase, must have at least one lowercase, must have at least one number (0-9), and must have at least one symbol (@,#,!,$). password can not contain firstName , and can not contain lastName.
E-Mail must contain @ symbol, and there must be at least 3 letters in front and 3 letters behind the @ symbol. Email must end with 1 of these ( .com , .net , .edu and/or .org).
b) Once validation returns true for the session, the array of data should flow to store data in a file called final Data23374.txt . Each line in the file should have user data.
Make sure to handle Exceptions for input to file and output to file. So that log-in data can be retrievable. You should be able to append file if it exist already, and create if not.
(2) Log-In option - at the log-in menu
a) User should login with email and password. Data that is save from the sign-up option, should be available for user to login with email and password. If the email does not exist alert user, and if email does exist but password does not exist then alert user.
Note: Program should always have the option for the user to return to main menu. If the user enters correct email and password, alert user the good news or bad news either way.
(3) Exit option - at the Exit menu
a) The Program Ends - alert user the Program Ended.
