Write a Java program that manages students and their marks. Create a class called Student with the following attributes and methods: studentId name grades[] gradeCount getStudentId() addGrade(double grade) getAverageGrade() hasGradesAbove(double threshold) displayStudentInfo() Create two subclasses of Student: RegularStudent and HonorsStudent. The RegularStudent class should have an additional attribute: major. The HonorsStudent class should have an additional attribute: honorsProgram. Both subclasses should override the displayStudentInfo() method. In the Main class, create instances of the RegularStudent and HonorsStudent classes, and prompt the user to enter the details for each student. Add grades to each student by prompting the user to enter the grades.   Show all screenshots of all outcomes

In this question, we will bake a class. Create a class Cake , with the following instance attributes: • name (a string) • ingreds (a list of strings) • price (a float) The Cake class has also the following methods: • Write a constructor that takes as input a string indicating the cake name, and a list of strings indicating the cake ingredients. (No docstring needed.) The constructor uses these values to initialize the attributes accordingly. Note that each cake should be assigned a random price between $10.00 (inclusive) and $15.00 (exclusive). You may import random . Moreover, a cake must contain at least three or more ingredients. If this is not the case, the constructor should raise a ValueError . For this constructor, do not worry about making a copy of the input array. You can simply copy the reference received as input into the corresponding attribute. 1 • Write a method (including docstring) called __str__ which returns a string containing the name of the cake and its price…

Which is true? Group of answer choices A class can implement multiple interfaces A class can inherit from multiple classes A class can implement only one interface An interface can implement multiple classes

In Java!!!!!This is a multi-part question. Consider the following UML diagram on attached image: 1.Write Java classes corresponding to the UML diagram. 2. Write getters and setters for all classes 3. Write non-default constructors for each class that initializes all instance variables to values passed as arguments to the constructor 4. Write toString method for each class 5. Modify Vehicle class to maintain inventory (list of all vehicles created) and print the list. What variable(s) you need to add? What additional method(s) you need? What else needs to be modified in the Vehicle class? Do you need to modify any of the descendant classes and explain your answer (if not: why not; if yes, describe what changes).
