JUnit5 JAVA. Need help to make a unit test of my GenericStack.java code below. Feel free to change the code below to fit the task better. thanks :) Assigment Create a new version of GenericStack (Have started on the code below) that uses an array instead of an ArrayList (this version should also be generic). Be sure to check the size of the array before adding a new item; - if the array becomes full, double the size of the...

Start a new project in NetBeans that defines a class Person with the following: Instance variables firstName (type String), middleInitial (type char) and lastName (type String) (1) A no-parameter constructor with a call to the this constructor; and (2) a constructor with String, char, String parameters (assign the parameters directly to the instance variables in this constructor--see info regarding the elimination of set methods below) Accessor (get) methods for all three instance variables (no set methods are required which makes...
For this In-Class Exercise, you are asked to build a MATLAB code that makes a few assignment statements and a logical test with random numbers. To answer this ICE, you will need to upload a screenshot of your successful run showing ALL of the outputs. Remember to use good programing skills for the code. For your outputs: If your output for a step below is a single value, use a command similar to:fprintf(‘Question 5 answer: %4.3f \n,A) or fprintf(‘Question 5...

How should I refactor these code? We're supposed to refactor 5 things. Here's the conditon: A minimum of 5 refactoring operations must be performed. The refactoring operations must preserve the program’s functionality. For each refactoring operation, you must insert comments to -Give the refactoring operation a number, -describe what refactoring operation was performed, -give the rationale for your choice of the refactoring operation you have applied, and -put the original code (i.e. before refactoring) inside the comments public class StringOperations...
