InheritanceThe more general class is typically known as the parent class, super class, or base class. The more specific class is typically known as the childclass, sub class, or derived class.The Java keyword extends allows you to indicate that one class should be the child class of the original parent class.

Have they been declared as public or private?e. What do the access modifiers (public or private) mean for how the Student class may use the instance variable and methodsthat it inherits from the Person class?

Language/Type: Java classes Write a class of objects named Date that remembers information about a month and day. Ignore leap years and don't store the year in your object. You must include the following public methods: description constructs a new date representing the given month and day returns the number of days in the month stored by your date object returns the day returns the month advances the Date to the next day, wrapping to the next month and/or year if necessary returns a string representation such as "07/04" member name Date (m, d) daysInMonth() getDay() get Month() nextDay() toString() You should define the entire class including the class heading, the private fields, and the declarations and definitions of all the public methods and constructor.
Problem Description and Given Info For this assignment you are given the following Java source code files: IStack.java (This file is complete – make no changes to this file) MyStack.java (You must complete this file) Main.java (You may use this file to write code to test your MyStack) You must complete the public class named MyStack.java with fields and methods as defined below. Your MyStack.java will implement the IStack interface that is provided in the IStack.java file. You must implement your MyStack class as either a linked list or an array list (refer to your MyArrayList and MyLinkedList work). Your MyStack must not be arbitrarily limited to any fixed size at run-time. UML UML CLass Diagram: MyStack Structure of the Fields While there are no required fields for your MyStack class, you will need to decide what fields to implement. This decision will be largely based on your choice to implement this MyStack as either an array list or a linked list. Structure of the Methods As…

java oop languageCreate a Java class that describes a product in a store with relevant fields. A few examples of such fields would be name, brand, etc. Append the class with methods that allow a customer to buy that product and append the number of times the product is sold. The customer will be subjected to 13% tax on each buy, you will calculate the payable amount and display it on the console on each buy.
