hoose necessary patters, draw the UML and code just company class methods on paper. A car company makes a car produce application. There are diffrerent types of models that the company builds as sedan  and sport. Each model has some shared and distinguishing features. The object creation process should conduct by a central class. The second central class should not be created in the application.

1. For methods      parameters are specified in the method definition, arguments are provided during a method call     arguments are specified in the method definition, parameters are provided during a method call     arguments override parameters     parameters encapsulate arguments 2 Local variables are not automatically initialized.  True  False 3 Composition refers to an 'is-a' relationship.  True  False 4 Class constructors must be declared with a return type equal to the class.  True  False 5 Object instances are created using the “new” keyword.  True  False

Internally your program should have two Java classes: ValidatorNumeric (superclass) ValidatorString (subclass) The subclass ValidatorString extends ValidatorNumeric class, forming a hierarchy of two classes. Add a separate main class with the main() method to test all public methods in both ValidatorNumeric and ValidatorString classes. The main() method should create the necessary objects and run the user interaction as shown above. The ValidatorNumeric class is responsible for capturing user prompt and a range of valid numeric inputs. Its methods display the prompt and accept input from the user. It should provide the following public interface: // Default constructor ValidatorNumeric() // Specific constructor taking params as follows: ValidatorNumeric( String prompt, int min, int max ) // Another specific constructor taking params as follows: ValidatorNumeric( String prompt, double min, double max ) // Method that shows user prompt and gets an int from the user: public…

Create a Class Diagram and write pseudocode define each method in the class module for one of the following: 1. Submarine 2. Volcano 3. Planet You must also write pseudocode to show how objects of your <class> can be created, including the methods of the class that can be called to perform their respective tasks.

1. for this question do not write the code just explain how you would Create a class called Elevator that can be moved between floors in an N-storey building. Elevator uses a constructor to initialize the number of floors (N) in the building when the object is instantiated. Elevator also has a default constructor that creates a five- (5) storey building. The Elevator class has a termination condition that requires the elevator to be moved to the main (i.e., first) floor when the object is cleaned up. Write a finalize() method that satisfies this termination condition and verifies the condition by printing a message to the output, Elevator ending: elevator returned to the first floor. In main(), test at least five (5) possible scenarios that can occur when Elevator is used in a building with many floors (e.g., create, move from one floor to another, etc.). Hint: Termination occurs when the instance is set to null. You may wish to investigate “garbage collection” for this exercise.

What are the advantages of passing this data into a method as opposed to just passing it into the current class object?

The Factory method design pattern is useful since it can be used to create new objects of a particular type dynamically. True False

For this portion of the assignment you will need to create the Employee class * based on the instructions in the API and have implemented the Equals method for that class. * * There is one parameter being passed as to this method that you will use as part of your solution:* An Employee object reference with the identifier testEmployee* * 1) Instantiate an instance of the Employee class using the default constructor and * assign it to an object reference with the identifier defaultEmployee* * 2) Instantiate an instance of the Employee class using the alternate constructor, * passing the following arguments:* name: "Keanu Reeves"* ID: 10010* salary: 78000.00* Assign the instance to an object reference with the identifier keanuEmployee* * 3) Declare a variable of type Employee with the identifier excellentEmployee and assign it * a reference to the same object that is being referenced by the keanuEmployee object reference. * 4) Construct a selection statement that tests if testEmployee is…
