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...

Please help me with these two java programs. Don’t make it complex.

JAVA. THIS IS A PROGRAMMING ASSIGNMENT NOT A WRITING ASSIGNMENT IF YOU ANSWERED BEFORE DO NOT ANSWER AGAIN PLEASE DO NOT PASTE A PAPER Design a class to store the following information about computer scientists⦁ Name⦁ Research area(s)⦁ Major contribution A scientist may have more than one area of research.⦁ Implement the usual setters and getters methods ⦁ Implement a method that takes a research area as an input and return thenames of scientists associated with that area ⦁ Implement a method that takes a word as an input and return the names ofscientists whose contribution mention that word Next, perform desktop research to find at least five prominent black computerscientists, with their research area(s) and major contribution, and store this data intoobjects of the class you designed. You can just hardcode this data. No user input needed.Define JUnit tests to check your research area and contribution search methods.

Please show your code and result to solve this.

Design and implement the class Day that implements the day of the week in a program. The program should be able to perform the following operations on an object of the type Day: Set the day.

Java program: 1. Create a class named Rectangle that has instance variables height and width. Provide a constructor that initializes the instance variables based on parameter values, getter and setter methods for the instance variables, a toString method, and a method named computeSurfaceArea(), that returns the surface area of the rectangle. 2. Create a child class named RectPrism that contains an additional instance variable named depth. Provide a constructor, getter and setter methods for the new instance variable, and a method named computeVolume(), that returns the volume of the rectangular prism. Override the toString() and the computeSurfaceArea() methods. 3. Write an application called Demo, that instantiates a rectangle and a rectangular prism, and tests all the methods. Make sure you indent and comment your code based on the examples in the textbook. Don’t forget to include your name, the course number, title of the assignment, and today’s date.
