//Todo write test cases for SimpleCalculator Class
// No need to implement the actual Calculator class just write Test cases as per TDD.
// you need to just write test cases no mocking // test should cover all methods from calculator and all scenarios, so a minimum of 5 test
// 1 for add, 1 for subtract, 1 for multiply, 2 for divide (1 for normal division, 1 for division by 0)
// make sure all these test cases fail
public class CalculatorTest {

method does not need to return anything.
Add a method called isCone that takes in a true or false value of whether or not the ice cream is on a cone or
not. This method does not need to return anything.

- Cs101: Lab #12 Writing Classes II In this lab you will write three classes: Die, PairofDice, and Player. The Die class mimics the rolling of a die. Specifically, this class will implement the following methods: A default constructor initializing the number of sides of a die to 6. An overloaded constructor that takes an integer number of sides (assume greater than 1). roll which generates and returns a random number between 1 and the number of sides (inclusive). An accessor method to read the value of the face on the die. A tostring method returning the string representation of the face value. The maximum number of sides should be stored as a private constant in the Die class. Also use the Random class for the random number generator. The PairofDice class mimics the rolling of two dice.

Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3.

This is a cell that should alternate between being alive and dead with each generation. Add one or more of your AlternatingCells to your ConwayWorld. You can see how to add a cell in line 15 - 20 of Main.java. Give your AlternatingCell a unique display character when it is alive so that you can see it in your conway world. 2.
