CODE IN JAVA 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.

Create a flowchart and modify the code. INSTRUCTION: Create a new class called CalculatorWithMod. This class should be a sub class of the base class Calculator. 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…
