The client needs a program to store data on sandwiches, including bread name, filling name, and calories (cal) Testing values for get and set methods are bread name: “whole-wheat”, filling: “tuna”, and calories 250.50 Testing values for overloaded constructor are bread name: “rye”, filling: “chicken”, and calories 300.25 Using the word problem above, design a class with the needed fields, a no parameter constructor, an overloaded constructor with three parameters, and needed methods (gets sets). Document your design using a detailed UML Class diagram. Part 2 Write the Java code for the class Follow your UML class diagram and code the class you designed. Use Java coding conventions for identifiers: class, constructor, field, variable, and method names Mark fields private, constructor and methods public. Select and use appropriate data types for the fields as well as method parameters as needed. Comment your code as requested and demonstrated in the course. Part 3 Test the…
So RolePermission does not allow Static methods so I cannot create a findOrCreate() method in this class. And the addPermissions in RolePermissionServiceImpl requires a static method and not non-static. I am really confused here. And can you help with the body for findOrCreate method. May be that will help understand a little more:public static findOrCreate(Long roleId, Long permissionId){}
Which of the following statements are false? (All that are not true). Group of answer choices A reference of type super class can refer to an instance of type subclass. A reference of type subclass can refer to an instance of type super class. A method in the super class can be overridden two different ways in two different subclasses. A method in the super class can be overridden by changing its signature in the subclass.
in Java, 1. Write a class called Counter that has the following:- Data field counterIndex- Default constructor: initializes data field to zero- Overloaded constructor: parameter passed to initialize the data field- Write a getCounterIndex method: returns the counterIndex - Write a setCounterIndex method: sets the counterIndex to some value that is passed to the method- increase method: increase the data field by 1- decrease method: decrease the data field by 1 2. Write a CounterTest programWrite a main method that contains the following:- Create a Counter object called counter1 using the default constructor- - Create a Counter object called counter2 using the overloaded constructor and pass the value 5- Get the counter index for each object and store the values in integer variables a and b- Test if a is greater than b increase counter1, otherwise decrease counter1- Print the counter1 value after the test
Allow the user to automatically flip a coin 500 times. Keep track of the number of times heads and tails appear. Also, keep track of "heads" winning streaks and "tails" losing streaks. That is, keep track of how many times 1 head in a row occurs, 2 heads in a row, 3 heads in a row and so on, and the same for tails. Be sure to separate all functions and methods (if you chose to use a class or structure) into both the prototype and an implementation below the main. 1. Write a regular c-type function that returns a random bool 1 = "heads" and 0 = "tails". Use the following prototype: bool coinFlip(void); 2. When the user plays the game, flip the coin 500 times automatically. Keep track of the number of "tails that come up", "heads that come up", the number of "heads" winning streaks as well as the "tails" losing streaks. The output may look something like this, where the code was only run 100 times: You flipped a coin 100 times:Number of heads = 54Number of tails = 46Heads winning…
Create a class Divide with the following fields, constructors and methods:Fields: create two double fields called numerator and denominator Constructors:- a no-argument constructor- a constructor with two parameters Methods:- write a getter to return the result of numerator divided by denominator- Create 4 overloaded calculate methods. Note: Division would be numerator divided by denominator 1. method receives two double parameters and returns the result of the division as double 2. method receives two integer parameters and returns the result of the division as double 3. method receives one integer parameter and another as double parameter and returns the result of the division as int 4. method receives two String parameters and returns the result of the division as int Create a demo class to test the two constructors, all the methods and display the returned values. You can hard code the parameters values when calling the constructor and the methods.
If you don't decalre a method as public or private, would the method be defaulted to public, private or something else? Here's a portion of my code that ties to this question:static int HCPTracker(ListInterface<Card> hand) { //Method detects if a hand contains an Ace, King, Queen, or Jack int HCPCount = 0; Card aceRef = new Card(Rank.Ace,null,null); //Allows the method to detect Aces, Kings, Queens, and/or Jacks Card kingRef = new Card(Rank.King,null,null); Card queenRef = new Card(Rank.Queen,null,null); Card jackRef = new Card(Rank.Jack,null,null);
In the class definition, initialize the private fields owner (string), rating (integer), and state (string) with the default values "Unstated", -1, and "Undefined", respectively. Ex: If the input is Ken 4 NY, then the output is: Default values: Name: Unstated's Food Truck, Rating: -1, State: Undefined After mutator methods: Name: Ken's Food Truck, Rating: 4, State: NY Note: The class's print() method is called before and after the input is passed to the setters. Eatery.java public class Eatery { private /* Your code goes here */ private/* Your code goes here */ private/* Your code goes here */ publicvoidsetOwner(StringeateryOwner) { owner=eateryOwner; } publicvoidsetRating(inteateryRating) { rating=eateryRating; } publicvoidsetState(StringeateryState) { state=eateryState; } publicvoidprint() { System.out.println("Name: "+owner+"'s Food Truck, Rating: "+rating+", State: "+state); } }
1) Through BlueJ, the class must define a method called isSpace that allows the book club staff to determine whether there is enough capacity for a group to attend. This method must take a single integer parameter representing the size of the group, and return a boolean result. The method must work as follows: If the value of the parameter is less-than or equal-to 0 then the method must return false. This case has priority over those following. If the value of the parameter is less-than or equal-to the space left in the book club (use the capacity and occupancy values in the to work this out) then the method must return true. Otherwise (i.e., if there is not space in the book club for the whole group) then the method must return false. 2) This method must not change the state of the BookClub object. In other words, both the current number of occupants and the capacity of the club must be exactly the same after it is called as it was before (Note that the return type of this method…
Write the definition of a class Player that has the following methods: • An __init__ method that initializes the following attribute variables: o An attribute variable named name , initialized to the empty string. o An attribute variable named score , initialized to the value 0. • A method named set_name that accepts one argument that is assigned to the attribute variable name . • A method named set_score that accepts one argument that is assigned to the attribute variable score . • A method named get_name that accepts no arguments, and returns the value of the attribute variable name . • A method named get_score that accepts no arguments, and returns the value of the attribute variable score .
Given the class declaration and instance method definitions and based on what you learned about separate compilation, what would be a good name for the header file containing the declaration, and what would be a good name for the source file containing the instance method definitions? // This is the class declaration class Rectangle { public: Rectangle(double width, double height); double get_height() const; double get_width() const; double get_area() const; private: double _width; double _height; }; // This is the instance method definition Rectangle::Rectangle(double width, double height) { _width = width; _height = height; } double Rectangle::get_height() const { return _height; } double Rectangle::get_width() const { return _width; } double Rectangle::get_area() const { return _width * _height; }
