Java -
All objects in a sorted list must be objects that can be compared to each other. True or False?
Step by step
Solved in 2 steps
- Write Java code Objectives •Use an abstract data type for a list •Use a method that contains an Object type as a formal parameter •Use methods in an existing class •Access data members within a class Required Files: •ListInterface.java •ListException.java •ListOutOfBoundsException.java •ListArrayBased.java Description A list is an abstract data type used to store ordered data, and contains operations that fall into the following categories: (1) add data to a data collection, (2) remove data from a data collection, and (3) ask questions about data in a data collection. The operations which ask questions about the data in a data collection may include operations that determine if a data collection is empty, determine the size of a data collection, and retrieve the item at a given position in a data collection. A list should be able to contain any type of object. The methods for the List support any object as specified in the interface. In this assignment, the objects will be S trings.…Parallel Lists JumpinJive.py >- Terminal Summary 1 # JumpinJava.py - This program looks up and prints t and prices of coffee orders. 2 # Input: In this lab, you use what you have learned about parallel lists to complete a partially completed Interactive Python program. 3 # Output: Name and price of coffee orders or error if add-in is not found 4 The program should either print the name and price for a coffee add-in from the Jumpin' Jive 5 # Declare variables. Coffee Shop or it should print the message "Sorry, we do not carry that.". 6 NUM_ITEMS = 5 # Named constant 8 # Initialized list of add-ins 9 addIns = ["Cream", "Cinnamon", "Chocolate", "Amarett "Whiskey"] Read the problem description carefully before you begin. The data file provided for this lab includes the necessary input statements. You need to write the part of the program that searches for the name of the coffee add-in(s) and either prints the name and price of the add-in or prints 10 the error message if the add-in is not…please code in python Forbidden concepts: recursion, custom classes Create a program for a used car dealership that buys and sells cars.

- Data structure & Algrothium java program Create the three following classes: 1. class containing two strings attributes first name and last name.2. class containing the name object and an ArrayList of string to store the list gifts. This class would extend the attached NicePersonInterface.java3. class containing one ArrayList of Names to store the naughty names. Another ArrayList of NicePerson to store the nice names and gifts. Add atleast 4 names in each list and display all information.A list allows retrieval of information based on the contents of the information. in java True or FalseTrue/False 6. Polymorphism literally means "many changes."
- Assignment: Enhancing Dice Roll Stats Calculator Program Introduction: The project involves creating a program to roll pairs of dice, gathering statistics on the outcomes. Probability differs in the roll of two dice compared to a single die due to varied combinations. Dice Roll Series: User greeted with "Welcome to the Dice Roll Stats Calculator!" and prompted to specify rolls. Java classes: DiceRoller, Indicator, Validator. DiceRoller: Arrays: rollSeries (captures results), statIndicators (stores statistical indicators). Constructor rolls dice as per user request. Methods collect stats and print the report. Indicator class: Contains dicePairTotal and dicePairCount. Displaying Results: Sort statIndicators array before display. Indicator objects sortable by dicePairCount (implements Comparable). Example output:-----------------------dicepair rolltotal count percent---- ------ --------7 5 50%10 2 20%4 2 20%2 1 10% Tasks:…JAVA PROGRAM PLEASE MOFIFY THIS PROGRAM SO IT PRINTS OUT THE FOLLOWING TEST CASE: Enter a name to search or type QUIT to exit:\nAnnabelleENTERThe name 'Annabelle' was not found in either list.\nEnter a name to search or type QUIT to exit:\nxavierENTERThe name 'Xavier' was found in popular boy names list (line 81).\nEnter a name to search or type QUIT to exit:\nAMANDAENTERThe name 'Amanda' was found in popular girl names list (line 63).\nEnter a name to search or type QUIT to exit:\njOrdAnENTERThe name 'Jordan' was found in both lists: boy names (line 38) and girl names (line 75).\nEnter a name to search or type QUIT to exit:\nquitENTER IT HAS TO SAY Enter a name to search or type QUIT to exit:\n THEH I PUT THE NAME ANNABELLE THEN IT PRINTS OUT: The name 'Annabelle' was not found in either list.\n THEN IT REPEATS Enter a name to search or type QUIT to exit:\n THEN I PUT THE NAME xavier THEN IT PRINTS OUT: The name 'Xavier' was found in popular boy names list (line 81).\n AND SO ON.…Part 5. Operator Overload: add Next, you will add the ability to use the addition operator (+) in conjunction with Simpy objects and floats. You will implement add such that the left-hand side operand of an addition expression can be either a simpy object or a float value using a Union type. The add_method should return a new Simpy object and should not mutate the object the method is called on. When the right-hand side of an addition expression is also a simpy object, you should assert that both objects' values attributes have equal lengths. Then, you should produce a new simpy object where each item in its values attribute corresponds to the items of the original Simpy objects at the same index added together. For example: a = Simpy([1.0, 1.0, 1.0]) b = Simpy([2.0, 3.0, 4.0]) c = a + b print(c) # Output: Simpy([3.0, 4.0, 5.0]) When the right-hand side of an addition expression is a float value, you should produce a new simpy object where each item corresponds to the item at the same…
- @6 The Reference-based Linked Lists: Select all of the following statements that are true. options: As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.For beginning Java, need help with this: " Purpose: Define class using OO approach Understand how to create and manipulate list of objects Design and create a well-structure program using basic programming constructs and classes Description: Write a program to help you to manage courses you are taking this semester. Your program provides the following options: List all courses Add a course Search word: show all the courses that has the word in the course title (ask the user for the word) List >= input-unit: show all the courses that has unit >= input-unit (ask the user for input) Exit Explanation of options: The program prints your course list. Initially, it should say “Your list is empty” The program asks the user input for a course including: course ID, number of units and title. The program asks the user to input the search word. Then, display all courses that has that word in the title. The search must be case-insensitive. For example, “computer” and…PYTHON: Code a traversal in python.
