- Create a class Course to describe a course according to the following requirements: A course has three attributes: courseName, courseCode, fees. Create a constructor without parameters to initialize all the instance variables to default values (0 for numbers and "" for a string). Create a constructor to initialize all the attributes to specific values. Add all setter and getter methods Create a tester class with the main method. The tester class must be named using your first and last In this class performs the following: Create a course object c1 using the default constructor. Create a course object c2 with the following information: courseName =” object oriented programing”, courseCode = “CS230” , fees = a value from your choice. Change the course fees of c2 to your age. Print the course information of c2 using getter methods I attached Typical run of the programWhich of the following does NOT apply to the strategy design pattern?

Game class instructions:• Game class has three attributes: points (which represent the number of points awarded when winning the game), status (false if the game has not been played and true if the game has been played), and description (which is a text description of the game). Note that description attribute is a read-only variable. • In the constructor, initialize points to zero, status to false, and description to the given parameter.• isPlayed method returns true if the game has been played, and false otherwise.• getPoints is a getter method for points attribute.• play method is an abstract method.• Override toString method to return the game description.• Override equals method so that two games are the same if their descriptions are the same. :instructions class ) HangMan• HangMan is a game in which a player tries to guess a word based on a given hint. For example, if the given hint is…a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).Q# A program that has no graphical user interface and only takes input through the command line only has a model and a controller. It does not have a view. The answer: is FALSE. Please explain with example. Q# What is NOT an effect of the SOLID principles? The answer: A high-level class depends on specific low-level classes and not interfaces. Please explain why. Q# Assume you are considering writing a method and are deciding what should happen when given input that is outside of perfect input. Which of the following is not a way to handle this?

RobotFriend is a new toy just on the market. Copy the starter class and the tester from Codecheck. A RobotFriend has a name and replies to various commands Provide a constructor that takes the name of the RobotFriend as a parameter. Remember that a constructor has the same name as the class. What does the class need to remember? That is the instance variable. Provide the following methods: public String getName () gets the name of this RobotFriend • public void setName (String newName) sets a new name for this RobotFriend • public String whatDoYouNeed () returns a string consisting of name + needs a battery charge" where name is the name of this RobotFriend (which was supplied in the constructor) public String doCommand (String whatToDo) returns a string consisting of "Your friend " + name + does not + whatToDo where name is the name of this RobotFriend and whatToDo is the parameter
- Description what the JAVA should execute: Create a new project called Family. Add a person class with name, birthDate, and sex private instance variables. Create the public getter and setter methods for each. Create an overloaded constructor that initializes all of the instance variables. Create the default constructor. Override the toString() method to show the Person's info. Create the Person in the main method, and display that person's info. Now add a new instance variable to the Person class of type Person with the identifier spouse. Spouse should be private with setter and getter methods. If you try to instantiate spouse in the contructor, you will get a stack overflow error. Each Person, creates a Person, creates a Person, and so on forever.
