Simple factory is not considered a design pattern because it does not decouple the client from concrete classes
Step by step
Solved in 2 steps
- Static class members are exactly what they sound like. When and how can they be used?- Simple factory is not considered a design pattern because it does not decouple the client from concrete classes Select one: True False 2- structural patterns provide guidance on the way in which classes interact to distribute responsibility Select one: True False 3- The Simple factory is used when you want to limit the instantiation of classes to one implementation Select one: True False 4- When a class A is composing a reference to another class B, then we say that class A has-a class B relationship Select one: True FalseWhen a concrete class inherits from an abstract class, you have to implement all abstract methods declared in the super class before you can instantiate it (the concrete class). True False
- PLZ help with the following IN JAVA When defining an inner class to be a helper class for an outer class, the inner classes access should be marked as: Public Private Protected Package accessTo implement an interface, a concrete class must implement AT LEAST ONE method heading.What does it mean that a method or class is abstract?
- Code the StudentAccount class according to the class diagramMethods explanation:pay(double): doubleThis method is called when a student pays an amount towards outstanding fees. The balance isreduced by the amount received. The updated balance is returned by the method.addFees(double): doubleThis method is called to increase the balance by the amount received as a parameter. The updatedbalance is returned by the method.refund(): voidThis method is called when any monies owned to the student is paid out. This method can onlyrefund a student if the balance is negative. It displays the amount to be refunded and set thebalance to zero. (Use Math.abs(double) in your output message). If there is no refund, display anappropriate message.Test your StudentAccount class by creating objects and calling the methods addFees(), pay() andrefund(). Use toString() to display the object’s data after each method calledIn Java programming (Lesson: Objects, Classes, and Constructors) Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class. False or True Please provide an explanation for the answer. Thank you!Design a new Triangle class that extends the abstract GeometricObject class: Draw the UML diagram for the classes Triangle and GeometricObject Implement the Triangle class Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled: The program should create a Triangle object with these sides and set the color and filled properties using the input The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not
- Write a constructor for the IceCreamCup class. The constructor takes the name, and a List of Flavor s (name it fList) as parameters. It initializes the instance variables with the parameters. Use shallow copy for initializing the list of Flavor s. (Throw an IllegalArgumentException if the name is null, or the Flavor list is null or empty.) Note that successful instantiation should increase nCups by 1.Example in Java Write and use classes with instance variables and their getters and setters. static and/or constant data default and overloaded constructors methods and overloaded methods toString() equals() 7. aggregationUsing c++ Design a Wacky class that can be used to generate a message based on the information passed to it. The class should have a single integer private member variable: int num; Design the complete class so that if: an object is created with no parameters; num is initialized to 10. an object is created with 1 parameter that is an integer; num is initialized to the integer that is passed *2 an object is created with 1 parameter that is a double; num is initialized to the double *4 an object is created with 2 parameters, a char and a string; it prints the message "That's WACKY!"
