java languageCreate a class with following attributes: The car's make The car's model The car's year Now let's identify the class's methods. Specifically, the actions are: Constructor of Car class Set and get the car's make Set and get the car's model Set and get the car's year Now create few instance of the Car in a Test class. Use getter and setter to set the instance variables. Create a class with following attributes: The car's make The car's model The car's year Now let's identify the class's methods.

A. Create a program by using OOP concept 1. Create a 1 Parent class and implement it to 2 Child class 2. Inside the parent class create 4 methods and 3 abstract methods. 3. Inside the child class create at least 2 unique methods and constructor with at least 2 parameters. 4. Call all the methods from the Parent and child class by using object. 5. Call also the constructor of the child class.
The ACTION and METHOD attributes allow for various actions to be taken in both code and forms.
Discussion: Advantages of Methods This discussion has 2 parts: What are the advantages of using methods? Name at least 2 advantages and how you benefit from each. List at least 1 scenario you would want to use methods instead of having the code in the main class.
- Simple factory is not considered a design pattern because it does not decouple the client from concrete classes Select one: True False 2- structural patterns provide guidance on the way in which classes interact to distribute responsibility Select one: True False 3- The Simple factory is used when you want to limit the instantiation of classes to one implementation Select one: True False 4- When a class A is composing a reference to another class B, then we say that class A has-a class B relationship Select one: True False
Design a class named CustomerRecord that holds a customer number, name, and address. Include separate methods to 'set' the value for each data field using the parameter being passed. Include separate methods to 'get' the value for each data field, i.e. "return" the field's value. Pseudocode:
1. Create a class called Plant with the data member plant name and color. 2. Create a child class called Tree with data member tree name, tree number and color. Inherit all the properties and behaviors from the base class to the child class. 3. Find the total number of times, character ‘a’ available in the plant name and tree name and display the method name as compare. 4. Use display method in both the classes to display“I am Plant” in parent class, and “I am Tree” in child class with all inputs needs to be displayed. Note: Get all the inputs through scanner class.
Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc.  Then create characteristics (breed, age, size, color) can form a data member for your object. Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.

Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member to represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. The constructor should validate the initial balance to ensure that it is greater than or equal to 0. If not, set the balance to 0. Provide three member functions:- credit($amount) should add amount to the current balance- debit($amount) should ensure that amount does not exceed the current balance and then reduce the current balance by amount. The balance should not change if amount exceeds the balance.- getBalance() should return the current balanceNote: Create a set of test data and then write a program to test the class.
Design a class named octopus that holds attributes for an octopus named weight and color. Include methods to set and get each of these attributes. Create the class diagram and write the class pseudocode that defines the class. Create a small program that declares two octopus objects and set the octopus's name weight and color attributes the program must also output each octopus's name weight and color after they are set. Please write out the pseudocode. I have a hard time with this.
