Unix-based operating systems usually include a tool named tail. It displays the last 10 lines of a file whose name is provided as a command line argument. Write a Java program that provides the same behavior i.e. the user can specify how many lines to print from the terminal. Display an appropriate error message if the file requested by the user does not exist, or if the command line argument is omitted.

Create a main( ) java file to perform the required tasks. Validate a user’s input (a menu option) to ensure its validity. Test and document your program to make sure that all of the required tasks are met. The main( ) creates a menu for a bank manager and a bank customer. For a bank manager, he/she can add information of bank customers and display all customer records. For a bank customer, he/she can make a deposit to a bank account and withdraw money from the account. Hint: The main ( ) could have a static method that allows a bank manager to add customers’ information to a text file. The information consists of Customer ID, Name (full name), and Email Address. Note that a loop should be used to perform the manager's task. As a result from the process, a text file "BankCustInfo.txt" is created. Also, the main( ) could have another static method that allows the bank manager to display all customer records to the screen. Create a class, BankCustomer, that contains attributes such as…

Write a Python program for a simple quiz game. The questions and answers are stored in a text file named "questions.txt." Each line in the file represents a question and its corresponding options and correct answer in the format: "Question, Option1, Option2, Option3, Option4, CorrectOption." The program should load the questions from the file, present them to the user one by one, and keep track of their score. Allow the user to input their answer, and after completing the quiz, display their final score. Make sure to handle cases where "questions.txt" does not exist or has incorrect formatting. Use functions to structure your code, making it easier to understand and maintain. You can use a list or dictionary to store the questions and options. Ex: questions.txt: What is the capital of France?, Berlin, London, Paris, Madrid, 3 Who is the author of "To Kill a Mockingbird"?, Mark Twain, Harper Lee, J.K. Rowling, Ernest Hemingway, 2 What is the largest mammal on Earth?, Elephant, Blue…
