Do not cheat. 填空题 The JDK command to compile a class in the file Test.java is The main method header is written as Suppose a Scanner object is created as follows: Scanner input = new Scanner(System.in); What method do you use to read a double type number? What is y after the following statement is executed? x = -1; y = (x < 0) ? 10: -10; What is the index variable for the element at the first row and first column in array a? 1. 2. 3. 4. 5.PythonComputer Science Consider a look-up service for the television shows on a given date. A file contains information about these shows. Each show’s data appears on two lines. The first line gives the name of the station, the channel, the name of the show, and a rating. These entries are separated by tildes (~). The second line briefly describes the show. Write pseudocode for a method with the header public void readFile(Scanner data) to read the file into a dictionary that will be searched. Decide what data should be the search key and what should be the associated value. Design any classes needed for the key and the value. Write pseudocode for the method Do not write any code for the answer. Use UML, pseudocode, and written Description.

- In java language Class Design – Date V0.0 & V1.0 Create a new project for this lab and create a new class inside called Date. If you created a Date class last week, you may use it as a base. What does it mean to be a Date? What data items (called “state”) do you need to keep track of? Alternatively, what does a date have? (“has a” == composition) What can a Date do? What are the actions and verbs that can be applied to a date? Come up with one or two. These become the class’s methods. Try adding 3 data items to your Date to manage the month, day and year. Should these be local variables? Class-level (or instance) variables? Now let’s build a method to set the date This function should take 3 integers as input and assign these to your instance variables declared in the previous step. public void setDate(int m, int d, int y) { And, let’s build a method to report the date This function takes no input and uses the console to output the Date in the format…import bridges.base.ColorGrid;import bridges.base.Color;public class Scene {/* Creates a Scene with a maximum capacity of Marks andwith a background color.maxMarks: the maximum capacity of MarksbackgroundColor: the background color of this Scene*/public Scene(int maxMarks, Color backgroundColor) {}// returns true if the Scene has no room for additional Marksprivate boolean isFull() {return false;}/* Adds a Mark to this Scene. When drawn, the Markwill appear on top of the background and previously added Marksm: the Mark to add*/public void addMark(Mark m) {if (isFull()) throw new IllegalStateException("No room to add more Marks");}/*Helper method: deletes the Mark at an index.If no Marks have been previously deleted, the methoddeletes the ith Mark that was added (0 based).i: the index*/protected void deleteMark(int i) {}/*Deletes all Marks from this Scene thathave a given Colorc: the Color*/public void deleteMarksByColor(Color c) {}/* draws the Marks in this Scene over a background…PATTERNS: Shapes Using Python, recreate (as close as possible) the pattern given using only one class - the Pattern class. You are only allowed to use PIL.Image and PIL.ImageDraw from the Pillow Library, and pi, cos, and pi. Its data attributes are as follow: width_height – 2-digit tuple containing the width and height of the image space – Image object (with 8-bit RGB color space, specified size, and background color) draw – Image object that performs as the drawing context of the space background – 3-digit tuple of the 8-bit RGB background color of the image or picture
- Complete the searching and sorting algorithms in ModuleOne and ModuleTwo of the modules package. Test all sorting algorithms in AlgorithmsTest. You must build everything from scratch and cannot use any methods in other Java packages to make your algorithm. Restrictions : All classes/methods must be made by you. You are ONLY allowed to use java.util.Arrays.toString method You are NOT allowed to use any other the Java API Library classes/methods.Take the following list of methods: Student () { // Creates a student object with all fields blank Student (String name) { // Creates a student object with a set name } Student (String name, Array []) { } power (int x) { // returns x^2 } power (int x, int y) { // returns x^y } greet (String name). { // returns "Hello, + name + " !"; } "1 a) What are your options if you want to find the value of a number squared? Which would you choose if you wanted the method to say something to the user? b) What 'Student' would you call if you want to create a student when you don't have any input? c) What 'Student' would you call if you had a whole array of data to input into the student object? d) Why do you think this is a capability that Java has? What uses can you imagine for it?Exercise 2. Create a Book class where: Each book contains the following information: book title book Author name, barcode (as fong integers), and book topic. o Implement an appropriate constructor(s) and all necessary get/set methods. Test Book class: o Create diffcrent book objects (at least 5 hooks) and store them in a LinkedList sorted by book barcode value Generate a unique random integer value for the barcode. Iterate through the LinkedList and print out the books' details O Create a second LinkedList object containing a copy of the above LinkedList, but in reverse order.
