• Create a class named Decimals. • Write a static method named printDecimalDigits that takes a double as a parameter and does not return anything. • The method should print out "Digits after decimal point: ", followed by all the digits after the decimal point on one line (do not include the decimal point). • Additional rule: Your code must not contain any loops. Create a test class named DecimalsTest that contains the main method and use the sample usage below to check your code. Method Call Decimals.printDecimalDigits (37.2) Decimals.printDecimalDigits (1000) Method Output Digits after decimal point: 2 Digits after decimal point: 0 Decimals.print DecimalDigits (18.3927493038) Digits after decimal point: 3927493038

PART B: JUnit Testing Write a Java program according to the following: Create a Multiple.java class. Create the following two static methods (with return type float): SquareRoot() and CubeRoot(). SquareRoot) method should take two arguments and return the float value at the end. CubeRoot() method should take three arguments and return the float value at the end. Create a test class with the name MultipleTest.java. In this class, import the following libraries at the top of this file import org.junit. Before; import org.junit. Test; import static org.junit.Assert.assertEquals; Create an object of Calculator.java class by writing the following code in CalculatorTest.java class: private Multiple multiple; @Before public void setup() {this.multiple new Multiple():) 4. Generate the JUnit test classes for both the methods one by one. Declare and initialize the required variables to pass those to the methods. Store the expected result in one of the variables and then compare it with the…
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

Class: DoubleMethod Write a method using the header below public static double readDouble(String prompt) that displays the prompt string, followed by a space, then reads a floating-point number from the user, and returns it. Here is a typical usage: salary = readDouble("Please enter your salary:");percentageRaise = readDouble("What percentage raise would you like?");Write a test program to test the method.

//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 { //Declare variable here private Calculator calculator; //Add before each here //write test cases here }
Part-1: Write a program that includes in its class the following methods: 1. A method named printChars that takes two characters and an integer with the following header: public static void printChars (char chl, char ch2, int numberPerLine) This method prints the characters between ch1 and ch2 with the specified numbers per line. Characters are separated by exactly one space. 2. A method named getLetters that takes two characters and an integer and returns a String with the following header: public static String getLetters (char ch1, char ch2, int numberPerLine) This method returns a String that includes the uppercase and lowercase English letters between ch1 and ch2 with the specified numbers per line. Letters are separated by exactly one space. 3. In your main method, use the methods you implemented to: a. Print all characters between 1 and Z, ten characters per line. b. Print all English letters between S and j, five characters per line.
A).In order to call another method in the same class, it must be declared before (above) the method that calls it. B). Changing the order that methods are declared in a source file has no effect on the run-time behavior of the program. C). How many parameters does the main method have? D). In the following example, how many arguments are passed to the printf method? E). What is the result type of Math.round(1.2345)? F). How do you write π 5 in Java? Write the expression itself, not the value 306.02. Don't write any semicolons or extra spaces. G). What value does the hello method return to main? H). What does the following program output to the user? I). If you're truly doing incremental development, all the code you write will be part of the final solution. J). Which type of comment does Javadoc process? K). Look up the Java documentation for the Scanner class. How many of its methods begin with the word next? Be sure to count the next() method.

True or False? Arrays cannot be passed as parameters, but must be used only in the main method.

Need help with part B the decode method AND the getChoice method using try/catch The program with the main method should be called ‘LetterCode.java’ The program with the class for performing the operations should be called LetterCodeLogic.java. The class should have two static methods: Encode and Decode (both of which receive a string parameter). Part A: The part A program will be the Encode function Part B: The Part B program will be the Decode function. This is my code so far for LetterCode.java: package lettercode; import business.LetterCodeLogic;import java.util.Scanner; /** * * @author Sean Jeffries */public class LetterCode { static Scanner sc = new Scanner(System.in); public static void main(String[] args) { int choice; String msg="", result=""; System.out.println("welcome to the Letter Code Program!"); choice = getChoice(); while (choice != 0) { switch (choice) { case 1: //encode…
