Inheritance is used in the decorator pattern to make the decorator have the same type of the component and to inherit its methods
Step by step
Solved in 2 steps
- Design and implement a class called Bulb that represents a light bulb that can be turned on and off. Initially, a Bulb object will be off. Create a driver class called Lights, whose main method instantiates and turns on some Bulb objects.When using an analogy involving a blueprint and a tree house, the ____________ is the class, and the ____________ is an object created from it. a. blueprint, tree house b. tree house, blueprintNote: write a java program given below. Q1: Create a class Component with properties width, height and color. Define the public methods draw, paint. Now, define few child classes of Component i.e. RadioButton, Checkbox, Button and List. Override the base methods and provide appropriate behaviors. Now create few instances of child components, call the methods paint and draw with these child classes
- Create a Visible interface with two methods: makeVisible and makeInvisible. Both methods should accept no parameters and return a boolean value. Explain how a class may implement this interface.Create a VisualCounter class that supports both increment and decrement operations. Take the constructor inputs N and max, where N indicates the maximum number of operations and max specifies the maximum absolute value for the counter. Create a plot that shows the value of the counter each time its tally changes as a side effect.In Netbeans: Create a JavaFX program that solves a multilayered problem using 4 to 5 or more related classes with commentation. ( please create UML diagrams for the classes)
- PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. PLEASE DONT EDIT THE TEST CLASS. Simulate a circuit for controlling a hallway light that has switches at both ends of the hallway. Each switch can be up or down, and the light can be on or off. Toggling either switch turns the lamp on or off. Provide methods public int getFirstSwitchState() // 0 for down, 1 for up public int getSecondSwitchState()public int getLampState() // 0 for off, 1 for onpublic void toggleFirstSwitch() public void toggleSecondSwitch()Which is NOT true of the decorator design pattern? It requires modification of the way an object is used It allows us to detach new methods to an object at runtime It allows us to attach new methods to an object at runtime It allows us to combine several features in a scaleable mannerWhen using an analogy involving a blueprint and a tree house, the _____________________ is the class, and the _____________________ is an object created from it. a. blueprint, tree house b. tree house, blueprint
- Create a new class called AdvancedMath that implementmyMath interface, which have following methods like sqr(),round(), floor(). These methods have to be implemented byAdvancedMath class.Design for the user without considering their interface. Create a catalog of the top methods.Classes – Write a class to represent a AlternativeEnergyCar. Select the fields and methods that fit the modeling of an alternative energy car. Make sure to include code for the constructors, set/get methods, a toString() method.
