- Write a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbeeCreate a class “Node” which is a single node of a singly linked list. The node stores an integer datatype. The class has two data members, an integer and pointer to the same Node class.Implement the following methods:1. The default constructor: Set value of the data member to zero2. A parameterized constructor: Node(int a); takes an integer variable and assigns it to the data member of this object. Set next pointer to NULL.3. Node* GetNextPointer() const; Retun next pointer of this Node4. void SetNextPointer(Node *ptr); Set the next pointer of this node to the ptr that is passed to the function.5. void SetData(int a); Set data of this node equal to ‘a’6. int GetData() const; returns the data of this object.The data member are private whereas the methods are public. part 4 5 and 6 In c++.Create a class “Node” which is a single node of a singly linked list.

- Create a SameItem Interface: The SameItem interface will be a generic interface.SameItem will have a single method: isSameAs(T) that returns a booleanWrite a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method score() of the parent class to calculate the weighted score for both types of students. Write a driver class JavaProgramming.java which has the main method. Create one remote student object and one in-person student object. The output should show prompts to enter individual scores – midterm, finals, ...... etc. and the program will…Given the IntNode class, define the getCount() method in the CustomLinkedList class that returns the number of items in the list not including the head node.

- A linked list is built in this lab. Make sure to keep track of the head node. ContactNode.java - Class definition ContactList.java - Contains main() method (2) Build the ContactNode class per the following specifications: Private fields String contactName String contactPhoneNumber ContactNode nextNodePtr Constructor with parameters for name followed by phone number Public member methods getName() - Accessor getPhoneNumber() - Accessor insertAfter() getNext() - Accessor printContactNode() Ex: If the name is Roxanne Hughes and the phone number is 443-555-2864, printContactNode() outputs: Name: Roxanne Hughes Phone number: 443-555-2864 (3) Define main() to read the name and phone number for three contacts and output each contact. Create three ContactNodes and use the nodes to build a linked list. Ex: If the input is: Roxanne Hughes 443-555-2864 Juan Alberto Jr. 410-555-9385 Rachel Phillips 310-555-6610 the output is: Person 1: Roxanne Hughes, 443-555-2864 Person 2: Juan…Complete the Kennel class by implementing the following methods: addDog(Dog dog) findYoungestDog() method, which returns the Dog object with the lowest age in the kennel. Assume that no two dogs have the same age. Given classes: Class LabProgram contains the main method for testing the program. Class Kennel represents a kennel, which contains an array of Dog objects as a dog list. (Type your code in here.) Class Dog represents a dog, which has three fields: name, breed, and age. (Hint: getAge() returns a dog's age.) For testing purposes, different dog values will be used. Ex. For the following dogs: Rex Labrador 3.5 Fido Healer 2.0 Snoopy Beagle 3.2 Benji Spaniel 3.9 the output is: Youngest Dog: Fido (Healer) (Age: 2.0)Data structure & Algorithum java program 1) Add a constructor to the class "AList" that creates a list from a given array of objects.2) Add a method "getPosition" to the "AList" class that returns the position of a given object in the list. The header of the method is as follows : public int getPosition(T anObject)3) Write a program that thoroughly tests all the methods in the class "AList".4) Include comments to all source code.
- 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.
