Define a java Name class with attributes: String firstname, middle name, lastname. Include the following methods: - A constructor with 3 parameters. Initialize the 3 member variables to the parameters being passed. Also, include the default constructor. - getter and setter methods for all attributes - override toString method Define a class called DebitCard. A debit card has a card number, Name and balance. a) Include a constructor with 3 parameters. Initialize the 3 member variables to the parameters being passed. Also, include the default constructor. b) Include getters/setters for all attributes. c) Add the following member functions: float inquireBalance() float depositCash(float amount) //increases the balance with amount boolean withdrawCash(float amount) // returns true if sufficient amount is available for withdrawal and decreases the balance by amount float interest(float rate) //calculates the interest rate incurred.

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.
