- Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class. Class name BankAccount Attributes _balance float _pin integer Methods init () get_pin() check pin () deposit () withdraw () get_balance () The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin () should return the pin. check_pin (pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit (amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw (amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful.

- Assignment:The BankAccount class models an account of a customer. A BankAccount has the followinginstance variables: A unique account id sequentially assigned when the Bank Account is created. A balance which represents the amount of money in the account A date created which is the date on which the account is created.The following methods are defined in the BankAccount class: Withdraw – subtract money from the balance Deposit – add money to the balance Inquiry on:o Balanceo Account ido Date createdParent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…Fill-in-the-Blank A class may have more than one constructor, as long as each has a different_________.
- True or False An interface can be used to define a set of methods that a class must implement.Homework Assignment Chapter 10b Create a new Java Project named Chap10b Create a class named Vehicle that acts as a superclass for vehicle types. The Vehicle class contains private data fields for the number of wheels and the average number of miles per gallon. The Vehicle class contains getters and setters for the data fields. The Vehicle class also contains a constructor receiving integer parameters for the number of wheels and average miles per gallons, and a display() method that prints the required output (use get methods). Create two subclasses, Car and MotorCycle, that each extend the Vehicle class. Each subclass contains a constructor that accepts the miles-per-gallon value as an argument and forces the number of wheels to the appropriate value-2 for a MotorCycle and 4 for a Car. Use the superclass constructor to set the wheels and mpg data fields (use the super keyword). Write a UseVehicle class to instantiate one object of each subclass and calls the display method to print…Object Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is…
