Make sure to type c++ in different files like Main.cpp, Person.cpp, Person.j, AddressBook.cpp, and AddressBook.h This small project is geared to test your understanding of File IO. AddressBook Exception Create an AddressBookException class that you can use to throw exceptions in your address book. Your class should have a constructor that will allow you to set the particular message that corresponds to the error. You should use your custom exception class to throw an error in the findPerson method if the person being searched for cannot be found, in the getPerson method if the AddressBook is empty. You should also throw an error any time that the addressbook file that…arrow_forwardHow did you decide to handle the possibility of queue underflow in java? A.

- How to answer the following questions screenshot shows the ArrayBoundedStack class and StackUnderflowException code The following expression is balanced: ( ( ( [ ) ] ) ) True or False Our StackUnderflowException code essentially consists of two simple constructors and "packages" and "extends" statements and nothing else. True or False which of these statements is the best representation of the current status of a Stack ADT in the Java Standard Library? A. There is no support for stacks in the library. B. The library provides a Stack class. C. The library does not provide a Stack class, but does provide other classes that can be used for the same functionality. D. The library provides a DeQue class that supports stack operations. E. The library provides a legacy Stack class, but it is better to use the DeQue class for stacks. the ArrayBoundedStack the topIndex variable holds the index of the elements array where the current top of stack is stored.

- In this assignment, you will implement the shell “engine” as the “group” component, where all members are responsible for the following functionality: • A Command-Line Interpreter, or Shell Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. 1. Interactive Mode In interactive mode, you will display a prompt (any string of your choosing) and the user of the shell will type in a command at the prompt.arrow_forwardWrite a java GUI program stacking Student objects of a class.

- OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly and provide the code with the screenshot of the output. Make sure to have the following methods below: -Push integers, strings, and names on the stack -Push booleans -Pushing an error literal or unit literal will push :error: or :unit:onto the stack, respectively -Command pop removes the top value from the stack -The command add refers to integer addition. Since this is a binary operator, it consumes the toptwo values in the stack, calculates the sum and pushes the result back to the stack - Command sub refers to integer subtraction -Command mul refers to integer multiplication -Command div refers to integer division -Command rem refers to the remainder of integer division -Command neg is to calculate the negation of an integer -Command swap interchanges the top two elements in the stack, meaning that the…arrow_forwardin my code there is a syntax error. i am trying to take out each character from inputted string and store each character into a linked list. i keep getting a syntax error stating that "non static method insertFirst(char) cannot be referenced in a static context" I have no idea why this is happening and i need help.
