You are to write a program that emulates an “undo” operation in programs like Word processors....
C# ONLY C# ONLY C# ONLY In this assignment you will implement the undo feature for a simple calculator. The undo feature must be implemented using a generic or template-based Stack data structure. You may utilize language supplied libraries (e.g. java.util.stack) or a stack implementation of your own design. No third-party downloads or software installs are allowed. The undo feature must allow for an unlimited number of undo operations. If the user attempts to perform an undo operation and the...
Modify the following given Java program. You are expected to modify the supplied Exercise1.java to print just the last lines of each paragraph in HTML format. Copy and paste the Sample input on the console then print the Expected output. import java.util.Scanner; public class Exercise1 { /** A simple static string for HTML & table header. */ private static final String HTMLHeader = "<!DOCTYPE html>\n" + " <html>\n" + " <head>\n" + " <title>CSE: Exercise 1</title>\n" + " </head>\n" +...
In the processLineOfData, write the code to handle case "H" of the switch statement such that: An HourlyEmployee object is created using the firstName, lastName, rate, and hours local variables. Notice that rate and hours need to be converted from String to double. You may use parseDouble method of the Double class as follows: Double.parseDouble(rate) Call the parsePaychecks method in this class passing the HourlyEmployee object created in the previous step and the checks variable. Call the findDepartment method...
Write a java class definition for a circle object. The object should be capable of setting radius, and computing its area and circumference. Use this to create two Circle objects with radius 10 and 40.5, respectively. Print their areas and circumference. Here is the Java class file (Circle.java). Compile it. public class Circle{ //Instance Variables private double PI = 3.1459; private double radius; //Methods public Circle ( ) { } //get method (Accessor Methods ) public double getRadius (...
In Java Code Needed is Below the Question Using Program 3: Encapsulating Dogs, modify this program to create a database of dogs of your own. You will also include File I/O with this program. You will create 3 classes for this assignment. The first class: Create a Class representing the information that is associated with one item (one dog) of your database. Name this class Dog. Using Lab 3, this will include the information in regard to one dog. The...
Hello, Can you please error check my javascript? It should do the following: Write a program that uses a class for storing student data. Build the class using the given information. The data should include the student’s ID number; grades on exams 1, 2, and 3; and average grade. Use appropriate assessor and mutator methods for the grades (new grades should be passed as parameters). Use a mutator method for changing the student ID. Use another method to calculate the...
PLEASE EDIT THE LAST 3 METHODS WHERE I PUT STARS AND DO WHAT THE COMMENTS SAY.

I have a little problem about my code. when i'm working on "toString method" in "Course" class, it always say there is a mistake, but i can not fix it: Student class: public class Student { private String firstName; private String lastName; private String id; private boolean tuitionPaid; public Student(String firstName, String lastName, String id, boolean tuitionPaid) { this.firstName=firstName; this.lastName=lastName; this.id=id; this.tuitionPaid=tuitionPaid; } ...
Add another public method called add to your Fraction class. This method adds another fraction to the ‘calling object’. Thus, the method will take a Fraction class object as a parameter, add this parameter fraction to the calling object (fraction), and return a Fraction object as a result. HINT: We can use cross multiplication to determine the numerator of the resultant Fraction. The denominator of the resultant Fraction is simply the multiplication of the denominators of the two other Fractions.Add...
What if you had to write a program that would keep track of a list of rectangles? This might be for a house painter to use in calculating square footage of walls that need paint, or for an advertising agency to keep track of the space available on billboards. The first step would be to define a class where one object represents one rectangle's length and width. Once we have class Rectangle, then we can make as many objects of...
