Write a class name FileDisplay with the following methods:
Constructor: takes the name of a file as an argument
displayHead: displays only the first five lines of the file’s contents. If the file contains less than 5 lines, it should display the file’s entire contents.
displayContents: displays the entire contents of the file, the name of which was passed to the constructor.
writeNew: displays the contents of a file, the name of which was passed to the constructor. Each line should be preceded with a line number followed by a colon. The line numbering should start at 1. As each line is displayed it should also be written to a new file, the name of which is passed in as a parameter.
I have provided a test file called “testfile.txt”. I have also provided a driver for the application called “filedisplaytest.java”. This file is complete and should not be altered.
Test File:
This is line one.This is line two.This is line three.This is line four.This is line five.This is line…
Rules:
Corner cases. Throw the specified exception for the following corner cases:
Throw an IllegalArgumentException if the client calls either addFirst() or addLast() with a null argument.
Throw a java.util.NoSuchElementException if the client calls either removeFirst() or removeLast when the deque is empty.
Throw a java.util.NoSuchElementException if the client calls the next() method in the iterator when there are no more items to return.
Unit testing. Your main() method must call directly every public constructor and method to help verify that they work as prescribed (e.g., by printing results to standard output).
Performance requirements. Your implementation must achieve the following worst-case performance requirements:
A deque containing n items must use at most 48n + 192 bytes of memory, not including the memory for the items themselves.
Each deque operation (including construction) must take constant time.
Each iterator operation (including construction) must take…
JAVA PPROGRAM ASAP
Please Modify this program ASAP BECAUSE IT IS HOMEWORK ASSIGNMENT so it passes all the test cases.
The program must pass the test case when uploaded to Hypergrade. Also, for test cases 1-4 it wants only to input Please enter the file name or type QUIT to exit: then input the file and display the Total number of words. For test cases 5 and 7 it wants to only to input Please enter the file name or type QUIT to exit then input input5.txt and then display File: input5.txt does not exist.\n then display Please enter the file name again or type QUIT to exit:\n then type input1.txt to display the total number of words or type quit to exit the program. For test case 6 it wants only to Please enter the file name again or type QUIT to exit:\n then type quit to exit the porgram.

Write the application SwimmingWaterTemperature containing a variable that can hold a temperature expressed in degrees Fahrenheit. Within the class, create a method that accepts a parameter for a water temperature and returns true or false, indicating whether the water temperature is between 70 and 85 degrees and thus comfortable for swimming. If the temperature is not between 32 and 212 (the freezing and boiling points of water), it is invalid, and the method should throw an ArgumentException. In the Main() method, continuously prompt the user for data temperature, pass it to the method, and then display the following messages indicating whether the temperature is comfortable, not comfortable, or invalid: X degrees is comfortable for swimming.

- In python Add the following four methods to your Crew class: move(self, location): This takes in a location as a string, along with self, and attempts to move the crew member to the specified location. If location is one of the five valid location options ("Bridge", "Medbay", "Engine", "Lasers", or "Sleep Pods"), then this should change self.location to that new value. Otherwise, the function should print out the message: Not a valid location. repair(self, ship): first_aid(self, ship): fire_lasers(self, ship, target_ship, target_location): The above three methods represent tasks that a basic Crew member is not capable of (but one of its derived classes will be able to accomplish). So each of them should simply print out a message of the form: <Name> doesn't know how to do that.

This class should also have an additional method for calculating the modulo. The modulo method should only be seen at the sub class, and not the base class! Include exception handling for instances when dividing by 0 or calculating the modulo with 0. You would need to use throw, try, and catch. The modulo (or "modulus" or "mod") is the remainder after dividing one number by another.Example: 20 mod 3 equals 2Because 20/3 = 6 with a remainder of 2 CODE TO COPY: #include <iostream> using namespace std; class Calculator{public:Calculator(){printf("Welcome to my Calculator\n"); } int addition(int a, int b);int subtraction(int a, int b);int multiplication(int a, int b);float division(int a, int b);}; int Calculator::addition(int a, int b){return (a+b);} int Calculator::subtraction(int a, int b){return (a-b);} int…arrow_forwardUse method which take a string parameter.
