The goal for Lab07 is to use the provided Student class and create an array of Student objects that is stored in a School object. This program uses a Student class that is provided(picture attached!). The class is placed in its own separate file and should not be altered. This project started with Lab06a and uses the same Student class. Part one of Lab07 is similar to the Lab06b. The difference is that Lab06b used static 1D arrays and Lab07 uses dynamic ArrayList arrays. The output is the same. In part two, adds the linearSearch and the binarySearch methods. Each search method is tested with an existing search record and one that does not exist.

Create a file named Question.py and then create a class on it named Question. A Question object will contain information about a trivia question. It should have the following: A constructor, with the following parameters: 1 string to be the question itself (for example: "When was Cypress College Founded?"). A list of four strings, each a possible answer to the question (only one of them should be correct) An integer named 'answer': the index in the list of the correct answer. Example: if the third answer in the answer list is the correct one, the client should pass 2 to this parameter to signify the correct answer is in index 2. Overload the __str__ method. It should return a string made up of the question and the four possible answers. A ‘guess’ method, with an integer parameter. If the 'answer' attribute matches the int passed to 'guess', return True. Otherwise, False On Main.py, in your main function, create a list and add four Question objects to it. You may give them with…
In this laboratory work, you are expected to write a c# console application to make some operations about the customers. Operations and required featurest that you need to cover in your program are following: • Add: This function adds a new person to json file. You need to get inputs from user and adds the new one into json file. • Display: This function displays all people in your json file. • Search: This function let you search with the user id. • Create Password: This function will create a random password for the user and user may choose the length of the password. Password may include numbers and characters. • Exceptions: You need to handle exceptions as well. You should at least handle 3 of exceptional cases. For the case that file can not be found, It is mandatory to catch the exception. Sample json string: "FirstName": "Kaan", "LastName": "OZAYDIN", "EmployeeId": 101, "Email": "", "Password": "Address": ( "ZipCode": "06460", "State": "Ankara", "Country": "Turkey" "FirstName":…
A class can be thought of as a/an for creating objects. Alternative Blueprint Compressed format Both A and B
What happens if you change the definition of a class by, say, adding an extra field, and then try to read back serialized objects created from the previous version of the class?
create an image file programmatically. Your image file should be called OnTheFlyPy.ppm and the code you write to create should be in a public static void makePPM() method defined in the provided Main.java class. Your OnTheFlyPy.ppm should be be 100 pixels wide and 100 pixels tall and the PPM header lines should be correct. The first two rows and last two rows in the OnTheFlyPy.ppm should be red (Red=255, Green=0, Blue= 0). The first two columns and last two columns in the OnTheFlyPy.ppm (except for the part that overlaps with the red pixels you created in the previous part) should should be blue (Red=0, Green=0, Blue= 255). The remaining pixels in your OnTheFlyPy.ppm image should be white (Red=255, Green=255, Blue= 255). Here is a picture of what your final image should look like: import java.io.*; public class Main{ public static void main(String[] args) { makePPM(); } public static void makePPM() { } }
1. Complete the class code below and include a method named "search" that takes two String parameters, a string to search and the other a target string to search for in the first string. The search method will return an integer representing the number of times the search string was found. The string being searched is a super-string formed by joining all lines of a text file, so we might expect to get multiple hits with our method. HINT: walk the String in a loop and use .substring(start, end) to examine a target-sized segment of the input string for equality to your target word. public class WordSearch { public static void main(String[] args) { String fileName String target = "help"; Scanner fileln = new Scanner(new File(fileName)); "story.txt"; %D String story = while(fileln.hasNextLine()) { story += fileln.nextLine(); // Build a super-String } System.out.printIn("(" + target + ") found "+ search(story, target) + " times"); } /l method code here } // end of WordSearch class
The goal for Lab06b is to use the provided Student class (ATTACHED IN IMAGE) and create an array of Student objects that are stored in a School object. This program uses a Student class that is provided and shown below. The class is placed in its own separate file and should not be altered. This program sequence started with Lab06a. It is a reminder that it is the same Student file used by Lab06a. This lab will add data processing to the earlier Lab06a. This program will continue with the Lab06b program that performs some data processing on the Student records. For this lab 10 Student objects need to be constructed and placed in a students array, which is stored in a School object. You actually did this already for Lab06a. You also need to complete the School constructor, addData method and toString Method, which were in Lab06a. Feel free to just copy them over. You need to complete three bubbleSort methods; one that sorts according to the student gpa., one for age and one for name.…
