Academic research System is composed of Member accounts and researches. The member accountsinclude name and ID of member and can do the following borrow, return and renew upto 4 researches. A research can have title, Bio and subscriber name and subscriber date. The researchclass can update the status of the research and store number of subscribers. Use the Visitor DesignPattern to visit these classes and retrieve some statistics about the objects, for example:The Leader can do the following when receive update from any subject:1. You can visit each research and assign return date to the end of next month.2. You can visit each member and empty list of subscribed researches.• Build class diagram using Visitor design pattern for this problem?• Implement your work in java?

Association (Reflexive) Association (Bidirectional) Association (Directed A to B) Association (Directed B to A) Composition (A as the whole and B as the part) Composition (B as the whole and A as the part) Aggregation (A as the whole and B as the part) Aggregation (B as the whole and A as the part) O Inheritance None of the given

Brainstorm below how you want to organize a game state class. This class keeps track of all information required to run the game. Remember, a class is composed of: State (data that is stored about an object) Behavior (behaviors of an object) For example, if you were to represent a Wordle game as a class, what data is stored within the game you’d want to have as member variables? What actions/behaviors can be taken?
2 part question I am using eclipse! Create a class Circle, which - has a field radius (double) It should have appropriate accessor and mutator. If the Circle instance is created without parameter, the radius should be set to 1.0. Otherwise the radius should be set to the specified value. The Circle class should have a class level (not instance level) field called Pi. Since Pi is a known constant (3.14159), this field should be a constant. This variable can be accessed directly by outside objects. This Circle class should have a getArea() method and getPerimeter() method. You need to decide their return value and access level. Note: Area = Pi * radius * radius Perimeter = 2 * Pi * Radius part 2 Create a subclass of Circle class ColoredCircle by implementing the ColoredShape interface. It should have a field color of type enum ShapeColor. ColoredShape.java ShapeColor.java ColoredCircle should have two constructors. One will takes one parameters radius and set the color to…
Follow the instructions from your instructor to accomplish the following in-class lab assignment. The Problem to Solve: The user needs a program to interact with employee records. The kinds of interactions are "Add an Employee" (Create record), "Show All Employees" (Read records), "View an Employee" (Read one record), "Update an Employee" (Update or change a record), and "Delete an Employee" (Delete a record). These interactions form the standard data processes in much of business software Create, Read, Update, and Delete, which are known by the acronym CRUD. The user needs to continue working with records until they are ready to tell the program. To do this, the program will present a menu of CRUD options and an option to Quit. The user will choose an option and the program will react accordingly. For this lab, the program will only print out which option the user chose. In later labs, we will add more functionality. Questions: What are the inputs needed to solve this…
Create your own UML diagram — similar to the below UML diagram — for a Pet class that meets thespecification below.1. Create the fields indicated below. Use these names exactly as given for your fields. Define them inexactly this order.• name — The name of the pet, e.g., “Rufus”, “Mittens”, “Smelly”, etc.• animal — The type of pet, e.g., “dog”, “cat”, “asparagus”, etc.• age — The (integer) number of years the pet has been alive, e.g., 1, 2, 3, etc.2. Create a mutator for each of the above in the order listed. Use the standard Java naming conventionfor mutators.3. Create an accessor for each of the above in the order listed. Use the standard Java naming conventionfor accessors

TODO 2 Complete the TODO by finding the locations of the data samples for each iris flower type. Hint: Use the code for how we found all the setosa_locs as an example! Using iris_df, find the location of all the data sample locations for the versicolor class which has a label of 1. To do so, use NumPy's np.where() function. Using iris_df, find the location of all the data sample locations for the virginica class which has a label of 2. To do so, use NumPy's np.where() function. setosa_locs = np.where(iris_df['class'] == 0)[0] # TODO 2.1versicolor_locs = # TODO 2.2virginica_locs = todo_check([ (type(versicolor_locs) is np.ndarray, "'versicolor_locs' is not type np.ndarray.

7. When a class contains objects of another class, the relationship is called a whole-part relationship or composition. The relationship created is also called a has-a relationship. Discuss some of the possible issues with composition, such as the long statement: Outputsales.getHighestPaidEmployee().getHireDate().getYear().

Add 2 constructors to the Course class. One that takes no arguments and initializes the data to all 0’s and “” (empty strings). And one constructor that takes all 4 arguments, one argument for each property and then sets the properties to these arguments that are passed in. Lastly change the main to use these new Constructors. You will not need to call the set functions any more, but do not remove the set functions from your class.
