- Review the programs StringCompare and SecretWord provided with this activity. Create a project named Chap3-LoginAuthenticator, then create a program (class) named Authenticate. The program should ask the IT Manager to enter his/her username and password and then verify the credentials. Note that the username is case insensitive, but the password is case sensitive. Assume an IT Manager's username is saved in the database as ssmith and password is saved as Falcons@2023, you will create 2 String variables to store these values. Here are is the output of three individual sample runs: Enter username: SSmithEnter password: Falcons@2023Login Authenticated... Welcome! Enter username: ssmithEnter password: Falcons@2023Login Authenticated... Welcome! Enter username: ssmithEnter password: falcons@2023Invalid username or password... Access denied! No submission is necessary, but you should have your code ready to demonstrate to the instructor for credit.The backup segment should be avoided in favor of the undo tablespace for a number of reasons. Do you have any evidence to support your claims?Learn the various access control methods. Examine each option's various controls.

- Write down the commands you would use for the following tasks Bob has a vital document named `sources.list` on his computer, but he doesn’t remember theexact location. So Bob asks you to help him find the file on his computer, and also, once it hasbeen found, please change the file’s permission, so only Bob can access it.Tasks:1. Find the file (sources. list).2. Change the file owner to yourself (Bob).3. Set access authority so that only you (Bob) can write/read this file.Note: since you are working on Bob’s computer, you are working under Bob’s name and have his privilegesAssignment 3 Design a GUI for Tasks Management. The Task data is: id, title, status, added by, creation date. Do the following: Add Task manually and from a file. View Tasks. Find All Tasks titles that added by “Ali" sorted by id. Find the top four tasks sorted by creation date. Find all tasks that start with the letter 'a' and have exactly seven letters (ignore letter 'a' case). Find who added the largest number of tasks. Find the number of tasks that are closed and open. Count the tasks that added by "Sami". Notes: Id is an integer value. Status can be (open or closed) only. Validate the add form fields and display error messages. Use the appropriate collections and functional programming to find results.Create a group called Authenticated Users.
